    #define question

    the character 'N' has the value of 78
    so would i define it as:

    #define N '78'

    so i can use it in this example:
    if (arr[i][j] == N ) {
    statement;
    }

    thanks

    no
    '78' is not a character
    if you want to declare a character with ascii value of 78
    just use 78
    eg.,
    char c=78;

    But since you can say

    if ( arr[i][j] == 'N' ) {

    You don't need to define anything, and you don't need to know the ascii value for N, and you don't even care if your character set isn't ascii.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    You are right , I was wrong , ascii has nothing to do with it , I meant the numerical value of the character .
