    Hello, I just started learning C

    Sorry for being a noob but I just started first C tutorial today, I have an experience in Perl Ruby, Perl VB and Pascal but not C, I would check out all of other tutorial on the site but it is mid night at me so here is what I want to know, when you print and scan a integer variable, you use
    Code:
    whatever("%d", &x);
    So what do you implement for %d when useing a Char, float etc.? Sry for being noob

    There's a nice little list - when you need a reference for stuff like that, Google's usually really good at finding what you need.

    And also, printf does not need the address of what you want to print (with the exception of strings), so...
    printf("%d", &myvar);
    ...is wrong.
    It should be
    printf("%d", myvar);
