Free() Function in C++
How is free() used in C++?
is used to free the memory pointed by the pointer back to the memory heap. This function should be called on a pointer that was used either with "calloc()" or "malloc()", otherwise the function will destroy the memory management making a system to crash.
void *free(void *ptr);
int main ()
int * ptr;
ptr = (int*) malloc (80*sizeof(int));
In the above example the first the memory is allocated using the "malloc()" then using the free() function the memory is freed.
