how to convert a long int to an int in C

Question

Mostly just the title, I want to know how I can put the random value which is a long int into an int variable address.

void SpinReel(int *a, int *b)
{
    long int reela = random() % 40;
    a= (int) reela;
    printf("&d\n", a);
    long int reelb = random() % 40;
    b= (int) reelb;
    printf("&d\n", b);

}

I am fairly new to C so I may just be misunderstanding the problem as well.

Just dereference `a` and `b`. You're 2 characters away from success. — ForceBru, Feb 26 '17 at 18:40

The parameter a is not an int but a pointer to an int. To assign a value, you need to dereference the pointer.

*a = (int) reela;

What dereferencing a pointer means

`a*` - > `*a`.. – ForceBru Feb 26 '17 at 18:41
