malloc in c

// Let's allocate enough space on the heap for an array storing 4 ints

intArray = (int *) malloc(4 * sizeof(int)); // A pointer to an array of ints

intArray[0] = 10;
intArray[1] = 20;
intArray[2] = 25;
intArray[3] = 35;

    {
        exit(0); // On arrête immédiatement le programme
    }

    // On peut continuer le programme normalement sinon

    return 0;

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.
