    Pausing a loop

    Very new to programming and I am trying to get a program to retrieve a file and number it if it has more than 24 lines of info it should stop until prompted by the user. I know it needs a loop but how do I retain the numbers i.e. 1-24 then 25-49.....

    in case you don't know what '%' means, it is modulus, and it returns the remainder of the division of two numbers

    so this means the remainder of linenum divided by 24 will be 0 every 24 lines
    47 / 24 = 1.958; //has a remainder of .958 so it doesnt work
    48 / 24 = 2; //has no remainder so it works, yay!

    The remainder and the decimal part of the quotient aren't equivalent.
    The remainder is an integer.

    The remainder of 47 / 24 is 23

    Code:
    if(wherey()%24==0)
    {
       cout<<"Press a key..."; getch();
    }
    //continue execution.
    Include conio.h and iostream.h
