You know, I've been messing around with arrays and I discovered that you can create an even cooler RNG program using arrays. All you have to do is create a for loop where the value of each element in the array is assigned to a seeded random number. Here's an example: #include #include #include using namespace std;void romba(int Input[], int Size);int main() { cout > y; int fofo[y]; srand(time(0)); for(int x = 0; x < y; x++){ fofo[x]= rand()%y; } romba(fofo, y); return 0; }void romba(int Array[], int Size){for(int x = 0; x < Size; x++){ cout
This guy really knows what he's teaching...Two topics in C++ that I found difficult to understand(Multidimensional array and this right here- passing arrays into Functions), he really demystified it all...Even in an easy to understand manner...10x bro...
Actually, the reason you don't pass bucky with square brackets is because it is a pointer to the first element of the array. You cannot pass the whole block of an array as an argument (mainly because it's very slow to copy the entire array), so you just pass the address of the first element.
yes you have to tell the computer that the elements in the array are integers, it makes sence too since array is nothing but a variable that can have different values at different time depending on the input, we treat x[ ] the same way we treat x
as an options, you can use a vector for this sort of thing, so you won't need to use second variable "sizeofarray". but probably it is more advanced lvl.
FYI (not sure if anyone else has mentioned this yet) if you don't want to worry about the array sizes or don't know the array sizes, look into using vectors.
use sizeof(nameOfArray) to determine the size of an array. This gives you the size in bytes so just divide it by the size of each element in your array, e.g int, float, long = 4 and double = 8. I'll throw in an example: int myArraySize = sizeof(myArray)/4;
the best way to explain why you don't need to label it as an array is because in your prototype you are calling for an array so it will automatically look for an one.
NICE TUTORIALS BUCKY! BUT INSTEAD OF PROTOTYPING FUNCTIONS YOU CAN JUST WRITE THEM BEFORE THE MAIN FUNCTION SO YOU DONT NEED TO COPY THE HEADER,IT WORKS FINE THAT WAY TOO.
I'm trying to make a card game and shuffle the cards, then deal them (3 cards will be dealt per play), but I keep getting multiple duplicate values for the shuffled and dealt cards. The values in the array are 0 - 51, each of which represent one of the 52 cards. Here are the two functions. top is the top card in the deck array and numCards keeps track of how many cards have been dealt. void shuffle(int numCards, int deck[ ]) { for (int top = 0; top < 52; top++) { int r = rand() % 52; int temp = deck[top]; deck[top] = deck[r]; deck[r] = temp; cout
Apparently there is no function to return the length of an array in C++. If you want to use the length of an array, you need to use sizeof(*name of your array*) / sizeof(*name of your array*[0]). Sizeof() returns the number of bits a variable has, so if you had an array consisting of integers, and your array had 20 elements, the size of your array would be 80 as the size of an integer is 4.
I have one question. When I define the function printArray before main function, I don't really need to prototype printArray (i.e. Declaration). The program run fine and I got no error or warning messages. How does that even work? Thx!
computer programs read the code from top to bottom, the reason why you need to prototype a function is because the function is defined after the main function, so the computer would have no idea what the function is since it hasn't read the function yet, that's why you need to prototype the function to let it know beforehand that this function will be defined later after the main function. if you define the function before the main function then there's no need to prototype it because the function has already been read before the main function.
No, an array has all of the same type of data. Hence, here the datatype is integer. If you wanted to do the alphabet you would probably use char array[] etc, but it can't mix numbers and characters. Hope this helps@Zakareya Alatoli
You aren't wrong when you state that "the reason why an array when called within main isn't using square brackets, is because the name of the array is "Jessica", That was just a little vague,More over it is because the function has taken the parameter of an array first. ex: "void blahblah(int whatever[ ], int sizeofarr)" so when called it will expect the first parameter you type to be the array. If you had passed the size and then the array ex:"(size, arr)"the program most likely not know what you are referring too. Correct me if i am wrong, if this helped Then You're Welcome.
C++ arrays don't have a Length property (or properties in the C# sense at all). For known sizes, it's best to use std::array, and for dynamic arrays, it's best to use another standard container, std::vector being a good one for general use.
@Chriscs7 Its better programming practice to write a prototype away from the body of the function, you'll see later on, it makes the code easier to read as well as makes the function more encapsulated which is very important as a programmer.
when calling the function, do you put the position of a value in the array in the square brackets when you want to pass the position instead of the whole array ?.
Why parameters in the void function are separated by a comma and not by a semicolon? I though parameters are as statements and need to be separated each by a semicolon as in case of a for loop. I Am now confused as when to use comma and when semicolon when separating parameters of different functions!!!
Making prototypes above the main function and then writing a code of that prototype is redundant action. You just can write the function above the function main and it will work perfectly without making a mess in code by typping additional lines.
After 3 months I admit that making prototypes is even better. When you don't make prototypes you have to plan your code so that inner functions have to be above outer ones. By pointing out making prototypes compiler knows about existence inner functions so they don't have to be above the outer ones. Quite helpful, isn't it ?
Not exactly. Commenting can be helpful, but has no effect on compiling. Declaring prototypes of your function tells the compiler that such function exists when is brought out without defining it above. This way compiler knows that there is no reason to panic since it reckons that if declaration was provided, definition will also be provided later.
When I make sizeOfArray bigger than it actually is, it steals the value of arrays that were declared before. example: int amazingArray[5] = {16,19,22}; int unrealArray[2] = {69,96,666}; realityBreakingFunction(unrealArray, 7); output: 69 96 666 16 19 22 WHAT"S GOING ON GUYS?
These C++ lessons are awfull and it uses OLD C++. Nobody in the right sense uses regular Arrays. Everybody uses STD::ARRAY It's an containered array. It's safer, got more handy futures build in and just as quick. I defined the size of the array in an oldfasioned way like this: int bucky[3] = { 2,95,304 }; int jessica[6] = { 45,46,78,34,45,2 }; printArray(bucky, sizeof(bucky) / sizeof(bucky[0])); printArray(jessica, sizeof(jessica) / sizeof(jessica[0])); // Number of elements are total size of array divided by the individual sizes of the elements, because different types use different memory sizes.
Hello Sir, Array can be overloaded or not,that means if we take two array with same name but different number of parameter,and we pass it through function call then it was not working.
They're just the names of the local variables. Think about it like this. say you have myArray[5] that you pass into function x(int localArray[], int arraySize) localArray is now a carbon copy of myArray, but they're not the same exact array, if you change something in localArray and don't return it, it WON'T change in myArray. same with arraySize, if you're using it in a for loop there isn't a function or command that allows you to access the array size off localArray, so you have to provide it for the function.
Actually, you don't have to write things like bucky[5] anymore... C++ can count how many elements in your array, so your initialization no longer needs the [5].
Somehow, I think it's a good practice to make sizeOfArray a const, just to avoid future changes into, that is to avoid getting funny things from compiler if you change by mistake the size of array in your external function. void foo( std::string name[ ], const int n) { ... }
Ok when I do it they change my array values to extreme values I changed the array from double to integer and still with the changing values What do you think is up with that
I know this is an old video but how would I create a function that takes a single-dimensional array, modifies it (for example, adds 1 to each element), and returns the modified array? It doesn't seem to be as easy as i would have thought.
i'm pretty sure you would just add 1 to each element by going through it in the for loop, like myArray[n] = myArray[n] + 1, then print that element using myArray[n] or something
hi, i want to implement an application that reads a file, modify its content and write the modification back to the same file? how i can do that? would u please give me some hint?
the prototype needed if function is defined under the main(), also you can just definde the function above the main() and dont use prototype. maybe i am a little bit late with it
Why do we need the parameter int sizeOfArray in the void function, and is the loop function "really" doing any calculation(i.e. the increment statement x++)? Because when we run the code it just print out the elements of the array as they are.
No it isnt doing any calculations, all the loop does is print out the contents of that specific element. The reason you need the sizeOfArray parameter is so that your loop can know how many times to run but also to make sure you don't go out of bounds. (which is when you try to loop an index which does not exist. Possible reason for a crash.) Hope i helped, Happy coding :)

the same way we treat x
Little tip for you guys: you can get the length of an array by using this:
int length = sizeof(array) / sizeof(/*arraytype eg.:*/ integer)

use sizeof(nameOfArray) to determine the size of an array. This gives you the size in bytes so just divide it by the size of each element in your array, e.g int, float, long = 4 and double = 8.
I'll throw in an example:

You're accessing memory after that array. All sorts of shit can happen :)

int bucky[3] = { 2,95,304 };

printArray(bucky, sizeof(bucky) / sizeof(bucky[0]));

OMG you saved me! very useful!
Hello Sir, Array can be overloaded or not,that means if we take two array with same name but different number of parameter,and we pass it through function call then it was not working.
When I run jessica with a size greater than the functions size, it starts showing bucky's integers, but the reverse does not happen. What causes this?
Is theArray[] a build-in function or so? How does it know it's Bucky or Jessica? Same goes with sizeOfArray.
They're just the names of the local variables. Think about it like this.
say you have myArray[5] that you pass into function x(int localArray[], int arraySize)
localArray is now a carbon copy of myArray, but they're not the same exact array, if you change something in localArray and don't return it, it WON'T change in myArray. same with arraySize, if you're using it in a for loop there isn't a function or command that allows you to access the array size off localArray, so you have to provide it for the function.

I believe you need that so you can check if x is less than sizeofArray
No it isnt doing any calculations, all the loop does is print out the contents of that specific element. The reason you need the sizeOfArray parameter is so that your loop can know how many times to run but also to make sure you don't go out of bounds. (which is when you try to loop an index which does not exist. Possible reason for a crash.) Hope i helped, Happy coding :)
