Nice. But structure array will reduce the redundant lines of your code. Try using that. Here is my code for reference. #include using namespace std; int score; struct Quiz{ string question; int answer; }; struct Options{ string option1; string option2; string option3; }; void results(Quiz *questions,Options *options){ for(unsigned int i=0;i
If I were you, instead of writing (or coding) "question1", ..., "question5", I would have code an array of questions for 5 elements, and thus your code could be more compact.

For last 5 day I am just searching out your channel and you even write a comment to me this morning. It is finally feeling me like "I CAN UNDERSTAND!" thanks for everything, you are the best teacher ever!
I am actually writing an ORM to abstract my SQL statements. One of the thing I did was create a way to map my C structures into the ORM like a virtual structure. Heavy use of pointers to the structure elements was used and became very helpful in the abstraction.
You are amazing, but you forgot to answer the most important question of all - what is the difference between a struct and a class... the answer is: The only difference between a struct and class in C++ is the default accessibility of member variables and methods. In a struct they are public; in a class they are private (at least per my understanding).
Most programming classes or structured college courses teach to always specify access modifiers explicitly in your code anyways, which somewhat makes the point moot to people with formal classes. But for beginners who do not take formal classes, you do have a point.
1) Well you can not have methods/functions inside a structure. 2) Structur is used for small stuff and class is used for big stuff 3) In struct members are public by default whereas in class they are private by default.
@@yashsonawane905 Structs can be large and complex. Remember, they existed before the concept of classes came to be. Which is why you rarely pass a large struct to a function by value, but rather a pointer to the struct.
Structures are stored in stack memory while classes use heap memory. A major difference which tells us about the time complexity and memory complexity.
I did the quiztest project and it was beautiful, I applied what you suggested with structures and nesting with "for", it took me 3 weeks to do it and I used the knowledge I acquired from you in the 10 hour course, Thank you very much! ❤️🤗

One thing i have learned is not to use single letter variables. The reason is that it is sooo tedious to search for a single-letter variable in a larger program. Just using 'ps' as 'person' instead of 'p' can save you from a lot of grief. Loop-Iteration-vars like 'i' is an exception, from that recommendation.

Hi Saldina, what are the main advantages to learn C++ that cannot be done or achieved with or via python. In other words, what are the main motive for a python expert to seriously dedicate time to master C++. And I wonder if there is extra specific advantages to master C++ as the only language for someone with a computational neuroscience background. Will be grateful for your reply. Thanks
C++ is faster, python is slower and Python is mostly used for data science and numbers calculations while C++ is used for application development more than data manipulation.
wow !!! thanks for the exercise, it wasn't easy for me but I did it :) at least it works, I don't know if the path taken is the right one but it's already a satisfaction tanks again.
structs are usually used as data containers, that is, without methods, and classes where you need to attach behaviour to your type altho you can make attributes private/public and have methods so it all depends on the style; usually that's the case
Generally spoken, both are they same. The difference is that with "struct" all members of a struct are public by default, whereas with "class" all members of a class are private by default.
I found myself wondering what the differences were between struct vs using class, meaning when it is important to use one vs the other. I went searching on youtube on the question, and the only pragmatic use difference I could find out is that struct is public by default, while class is private by default, otherwise don't they pretty much do the same things as each other? Sorry for asking what is probably a dumb question.
Perfect tutorials, good day everyone I'm struggling to create n make a delete function for an employment management system ..if there is any help I could upload it here if yall don't mind
Samsung used to be better both at performance and price but since last 3-4 years they raised their prices to match these of apple , which is crazy overpriced. Great lessons 👍 keep going
I have seen a few of your TH-cam videos on C++ and found them very well presented, easy to follow and informative in detail. However, on this occasion I found this to be a bit difficult to follow; seemingly a ramble through the process, lacking in explanatory detail. But, in the end, I had learned little. Nevertheless thanks for the stunning effort. Thanks.
Although at the first sight they appear almost the same they function differently At the base struct is a data type. Think of it as a special array with key value pair . Note that in C++ you can have methods in a struct. Class is not a data type. The first difference you will see is in a struct the data are by default public but data of a class are private. There are some differences in memory allocation. Use struct when you have a bunch of data that act like they stick together. As an example. Student as a struct. (Name grade major) Use a class when you have to do something more. Some computation or you need encapsulation of the data. Struct in C++ are kept to be backward compatible with C. ( that's just my opinion. You can write C style in C++ but that defeats the purpose of writing C++ code) But you can find use for them even if you write OOP like code.
ma'am please make videos on Data Structures & solution of this quiz problem. Ma'am really love your way of teaching. Just keep going.❤ You are the only one who focus more on foundation. Thank you ma'am.
I am watching the tutorial in june 2022 and the i phone cost is $699 right now. Greetings CodeBeauty. Thanks for your videos they've helped me a lot. I wanna become a software engineer.
Yes!!!!!!!!!!!!!!!!!! Make a video we go through it and also add one more example in that video showing how we can store the structures in case we are making lets say a project on cars...whereby at the end we will need to output a kind of form for all cars. Thank Youuuuuu

Hi Saldina!
How do structures compare to classes?
definitely, you are a very good teacher.
#include
using std::cout;
using std::cin;
using std::string;
using std::endl;
struct Question{ // ** Struct with question + 3 answer and a int for the correct choice **
string questionText;
string answer[3];
int correctAnswer= NULL;
};
bool correctAnswer(int correct) { // ** ask and check if the answer is correct or not with a bool **
int answer;
cout > answer;
while (answer > 3 || answer < 1) { // Check if the user enter a not valid number
cout > answer;
}
if (answer == correct) { // check if the answer is correct
cout
thanks! I learned a lot about function-bool-struct features from this one.
Just use ''using namespace std;'' at this poiint lol
Good but you could have used structure array
Nice. But structure array will reduce the redundant lines of your code. Try using that. Here is my code for reference.

string question;
int answer;

The output (cout) examples tied everything together; clean, succinct and paced very well with focused instruction and description (treatment).
You should do a video about c++ applications in real world , it will be so interesting your perspective!
I can't believe that u r back 😊😊
Back to stay 🤗💗💗
Hi ! Saldina .
i hope you are doing fine ?
i watchcd this tutorial yeasterday 29/august/2023 and i understood what is structure
and how they work. thank you about that .
the quiz of last part of lesson i was did, but i don't use loops b/c .l don't know how to use loops
in that more and different questions.
i only use array, structure, and cout, cin .
So much better than my professor 🥰😍
You should do a video with a counter to see how many requests for comments are possible in one lesson... (I was resisting commenting as hard as I could too! Well earned.)
I am new to programming dont whether this is the correct way to do this or not, but somehow this works
#include
#include
using namespace std;
struct questionOptions
{
string OptionA{};
string OptionB{};
string OptionC{};
int correctAnswer{};
};
questionOptions que;
void assignAns(string opt1,
string opt2,
string opt3,
int CorrectAnswer)
{
que.OptionA = opt1;
que.OptionB = opt2;
que.OptionC = opt3;
que.correctAnswer = CorrectAnswer;
}
int main(){
vector questions{
"Largest Country in the world?",
"How many states are there in India?",
"Biggest animal?",
"Non Rectangular flag of the country",
"Prime Minister of India"
};
int queSize = questions.size() - 1;
for (int i = 0; i
Hi Saldina, what are the main advantages to learn C++ that cannot be done or achieved with or via python. In other words, what are the main motive for a python expert to seriously dedicate time to master C++. And I wonder if there is extra specific advantages to master C++ as the only language for someone with a computational neuroscience background. Will be grateful for your reply. Thanks
C++ is faster, python is slower and Python is mostly used for data science and numbers calculations while C++ is used for application development more than data manipulation.
C# is easier than C++
wow !!! thanks for the exercise, it wasn't easy for me but I did it :) at least it works,
I don't know if the path taken is the right one but it's already a satisfaction
tanks again.
In what scenario it is better to use Struct and better to use class(OOP) in C++?
structs are usually used as data containers, that is, without methods, and classes where you need to attach behaviour to your type altho you can make attributes private/public and have methods so it all depends on the style; usually that's the case
Generally spoken, both are they same. The difference is that with "struct" all members of a struct are public by default, whereas with "class" all members of a class are private by default.
Thank you so much..... Your content is really Fricking cool❗❗
Congratulations for the 30K subs, u surely deserve more....keep making 😊💯
Thank you so much! I'm very happy and grateful for every single person who watches and likes my videos! 🤗🧡🧡
I found myself wondering what the differences were between struct vs using class, meaning when it is important to use one vs the other. I went searching on youtube on the question, and the only pragmatic use difference I could find out is that struct is public by default, while class is private by default, otherwise don't they pretty much do the same things as each other? Sorry for asking what is probably a dumb question.
Perfect tutorials, good day everyone I'm struggling to create n make a delete function for an employment management system ..if there is any help I could upload it here if yall don't mind
Another very good tutorial! Thanks!
best video ever !!!!!!!!!!!!!1 rarely ppl do functions use them in the argument they just spoke of.
super stoked mql5 is based on c++ haha // CB you rock!
Salina please do vectors; and how they interact with objects and pointers.
Samsung used to be better both at performance and price but since last 3-4 years they raised their prices to match these of apple , which is crazy overpriced. Great lessons 👍 keep going
hey saldina, what a different of the struct and union and how and when we use both of them? please explain in another video.
Beautiful video. My question is, what coding do you teach in your paid course ma'am ?
how do you decide when you should use a struct and some functions or an object an methods?
Very good and useful video...Task to test our knowledge is the best portion here....it would be good if u can provide the test after each video....
Ma'am please make a series on DS & Algo :)
In progress... 🤞😊
you're strong 💪 thank you
You're brave! Thanks 😃🤗
Is there a difference between a class and a struct?
#include
using namespace std;
void answerChecker(int input, int i) {
int correctAnswers[] = {2, 3, 1, 2, 3};
if(input == correctAnswers[i]) {
cout
So basically Records in Delphi... but I think it's important to mention that these structures represent a *heterogeneous* set of elements
I have seen a few of your TH-cam videos on C++ and found them very well presented, easy to follow and informative in detail. However, on this occasion I found this to be a bit difficult to follow; seemingly a ramble through the process, lacking in explanatory detail. But, in the end, I had learned little. Nevertheless thanks for the stunning effort. Thanks.
You explain things in great detail which is appreciated. What determines if you should use a struct or a class?
Although at the first sight they appear almost the same they function differently
At the base struct is a data type. Think of it as a special array with key value pair . Note that in C++ you can have methods in a struct. Class is not a data type.
The first difference you will see is in a struct the data are by default public but data of a class are private. There are some differences in memory allocation.
Use struct when you have a bunch of data that act like they stick together. As an example. Student as a struct. (Name grade major)
Use a class when you have to do something more. Some computation or you need encapsulation of the data.
Struct in C++ are kept to be backward compatible with C. ( that's just my opinion. You can write C style in C++ but that defeats the purpose of writing C++ code)
But you can find use for them even if you write OOP like code.
What a great and amazing definition!!!
Thank you very much 🤗🤗🤗
ma'am please make videos on Data Structures & solution of this quiz problem. Ma'am really love your way of teaching. Just keep going.❤ You are the only one who focus more on foundation. Thank you ma'am.
How do I do it with an user Input? For example the user should input his name, age and so on...and then the console should output the list
dislikers gonna dislike coz they suck at it! thank you ma'am for providing such quality content for free
Hey Saldina. How about you make a video for the solutionof the quiz app. Please 🙏
I am watching the tutorial in june 2022 and the i phone cost is $699 right now. Greetings CodeBeauty. Thanks for your videos they've helped me a lot. I wanna become a software engineer.
Congratulations for getting 63.1K subscribers, keep going on
Yes!!!!!!!!!!!!!!!!!! Make a video we go through it and also add one more example in that video showing how we can store the structures in case we are making lets say a project on cars...whereby at the end we will need to output a kind of form for all cars. Thank Youuuuuu
