    What is the effect of the simple code?

    Code:
    int n;
    n=7;
    printf("%c\n", n);
    i said it will print out the character '7' but i was wrong i guess.
    The correct answer is it will print out the character whose internal code is 7. Now when i see this is it telling me it printed out the ASCII code for 7 which is 7. Not alot of sense is being made here?
    can anyone please explain briefly why the correct answer is correct, please?

    It's printing a character whose "internal value" (as you put it) is 7. Look in the ASCII chart to find out more codes.

    If you want a "real" 7, you have to use
    >n = '7';

    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]

    printf("%c\n", n);
    Notice how it is treating it as a character with "%c"? If you wanted to print a 7 you would use "%d". See, if you wanted to print the character '7', you would have ot set n = 55 which is its ascii value.

    Check this out, it might help explain it to you.
