Objective C basics

Can someone explain this code to me and what it accomplishes. I don't get it.

    char h = 'h';
    char i = 'i';
    char j = 'j';

    char letter = 'i';
    if (letter == h) printf("letter %c is %c\n", letter, h);
    else if (letter == i) printf("letter %c is %c\n", letter, i);
    else if (letter == j) printf("letter %c is %c\n", letter, j);
    else printf("letter %c is %c\n", letter, j);

It checks if the variable "letter" is equal to h,i or j. In your case, "letter" is equal to "i" which means that it will print the message from the first "else if".

Let me know if I'm wrong.

I think you are right but I'm a long long way from designing an iOS app here. I guess I just have to be more patient. Baby steps....

Thanks for taking the time to answer my question. I would answer some questions but I don't know anything so I'm not much help to anyone yet.
