    Code:
    char var = 'A';
    
    printf("%c", var);  //not d
    
    //or
    
    int i;
    char string[] = { "How far to Andromeda?" };
    
    stringLength = strlen(string);
    
    for( i = 0; i < stringLength + 1; i++)
       printf("%c", string[i]);

    thanks Adak
    so if I wanted to create a program that outputted a letter that the user inputted, would it look like this:
    Code:
    printf ("Please input letter: ");
    int %c
    printf ("The letter you have inputted is: "%c);
    if that is true say I want the user to input a speific letter, would it look like this:
    Code:
    printf ("Please input letter: ");
    int X=A
    int X=B
    
    if X=A printf ("The letter you have inputted is A")
    if X=a printf ("Please input letter in captials") 
    if X=B printf ("The letter you have inputted is A")
    if X=b printf ("Please input letter in captials")

    So... if you want to create a program that output a letter that the user inputted you can do smthg like this:

    Code:
    char letter;
    printf ("Please input letter:\n");
    do {
    letter = getch();
    printf ("\nThe letter you have inputted is: ");
    putch(letter);
    }
    while (letter != 27);
    You can do this in many other ways.

    No, %c basically means printf will attempt to print a character (c for character) and %d means printf will attempt to print a decimal number.

    Code:
    char myCharacter;
    myCharacter = 'A';
    printf("%c", myCharacter);
    That would print "A".
    Thank you, anon. You sure know how to recognize different types of trees from quite a long way away.

    geekrockergal, you need to hit the books or tutorials to understand the basic syntax of C before proceeding.

    No. It has nothing to do with the length... 27 is the zecimal value of the ESC ASCII char. So that means do that until "ESC" is pressed.

    so is it possiable to do this (I want the user to input a speific character A or B)
    Code:
    char letter;
    printf ("Please input letter:\n");
    if {
    letter = getch(A);
    printf ("\nThe letter you have inputted is: A ");
    putch(letter);
    }
    else{
    letter = getch(a);
    printf ("\nPlease input a captial A ");
    putch(letter);
    }
    if {
    letter = getch(B);
    printf ("\nThe letter you have inputted is: B ");
    putch(letter);
    }
    else{
    letter = getch(b);
    printf ("\nPlease input a captial B ");
    putch(letter);
    }
    Im sorry people I really am trying my hardest to get my head around this

    Code:

    If WHAT? If you have an if, then you have then what, too, no?

    getch takes 0 arguments.
