    What does -> do?

    I am learning how to program in C, and I'm wondering what some things do in my tutorial program.

    Code:
    printf("%c -> ", i);
    What does this do?
    Here it is in context.
    Code:
    int main()
    {
        int u = 65;
        int l = 97;
        
        for(int i = l; i < (l + 26); i++)
        {
            printf("%c -> ", i);
            for (int j = u; j < (u + 26); j++)
            {
                if (j == (u + 25))
                {
                    printf("%c", j);
                }
                else
                {
                    printf("%c,", j);
                }
            }
            
            printf("\n");
        }
        return 0;
    }
    Thank you.

    So have you compiled and run this example?
    All problems in computer science can be solved by another level of indirection,
    except for the problem of too many layers of indirection.

    In this context, it's just two characters that are printed as-is to the screen in the first printf statement. They don't do anything special; most characters passed to printf are just printed directly.
    You ever try a pink golf ball, Wally? Why, the wind shear on a pink ball alone can take the head clean off a 90 pound midget at 300 yards.

    Thank you. I'm surprised I missed that when I ran the program.
