what does malloc do code example

Example 1: malloc c

int main(int argc, char *argv[])
{
    int* memoireAllouee = NULL;

    memoireAllouee = malloc(sizeof(int));
    if (memoireAllouee == NULL) // Si l'allocation a échoué
    {
        exit(0); // On arrête immédiatement le programme
    }

    // On peut continuer le programme normalement sinon

    return 0;
}

Example 2: how to use malloc in c

int* a =(int*)malloc(sizeof(int))

Example 3: Malloc

ptr = malloc(size); //You dont need to cast

Example 4: how to use malloc in c

ptr = (castType*) malloc(size);

Example 5: malloc syntax

ptr = (cast-type*) malloc(byte-size)

Example 6: what is the use of malloc in c

In C, the library function malloc is used to allocate a block of memory on the heap. The program accesses this block of memory via a pointer that malloc returns. When the memory is no longer needed, the pointer is passed to free which deallocates the memory so that it can be used for other purposes.
