Memory management

you will have to create such function yourself

Zia sahebi But closing the program does not automatically free allocated data so the program will leak memory (which may or may not be reclaimed by the operating system) and even if it does, it's a bad practice and not something you can expect if you want your program to be portable.

i say instead of doing many free(..) is it a function in standard library can do that once. exemple : function_delete(ptr1, ptr2...)

yea i can do it but i would be sure that he doesn't exist

In C++, you could do this quiet easily with template parameters: https://code.sololearn.com/c0C849P8kr3z/?ref=app

No there is no way to free all of your alloced heap memory at once except closing your programm!
