I can't believe the real badger from breaking bad gave up selling meth-amphetamine and decided to teach me how to use the c++ standard library. true hero :)
Thanks it worked for me. But i am kinda confused--> in the while loop u just used "FILE" as a length and u inserted the values in the vector "FOODS" using ""FOOD". How did it entered the values? I am not getting that part.
He didn't use file as the length, he used file >> food. Which evaluates to true so long as there is stuff to fetch from the file. That's what the condition is. it checks to see if you can read from the file, if the check is successful, the while loop iterates, and the push_back() function adds the food item into foods. If it is not successful, we exit the while loop and then the rest of the program continues.
Hi, I just want to create a file in cpp. I will update the contents of the file later. Can anyone share me the code for only creating a file? Sorry, I am actually confused with the C style file handling.
You would probably need to create a function that will alphabetize a bunch of strings, then feed the contents of the file through it. You would probably need to save them to a new file, or find a way to delete the contents of the first file and reupload them to it.

You explained this so simply and yet so effectively. Singlehandedly saving my course grade here. Thanks lots
thanks now i can create some kind of load and save system
Me too lol
I hope you sleep every night with sweet dreams. You explained it better than my professor did.

I don’t know if it’s me or you over complicated the c++ language this video made me forget c++ xd
loveyouuuu u help me to my problem

@@abdul4515 Ohhhhh that makes more sense! Thankyou!
Well explained
Please, do not use string or the bloat amount of libraries except for and . This is about new programmers learning C++.
I never saw someone eat lemons.
Good man.
if anyone can help, after I output something to a file I want to save the file, what do I do?
the file should automatically save when you close it and have the information you outputted to it
lemons
How to check if file exists?
check the cpp file
and you will see the txt file beside it
Hi, I just want to create a file in cpp. I will update the contents of the file later. Can anyone share me the code for only creating a file? Sorry, I am actually confused with the C style file handling.
#include
#include
int main()
{
std::ofstream file("filename.txt"); //change "filename" to whatever name you want.
file.close();
}
Say you make this file, and it’s to read names. How would you get the file to sort the names in alphabetical order?
You would probably need to create a function that will alphabetize a bunch of strings, then feed the contents of the file through it. You would probably need to save them to a new file, or find a way to delete the contents of the first file and reupload them to it.
You would have to create your own sorting algorithm and have some form of temporary string storage, as Sara said.
how would I use a function that writes its output as a string to a file
file
