    Concatnating strings that are too long for one line

    Hi, this is a really simple question but I can't figure it out. If I want to pass a really long string to a function, it is really inconvenient to keep it all on one line since then I need to scroll horizontally to see it all.

    I first tried using the + operator like:
    Code:
    function ("Long " +
        "String");
    However apparently I can't do that.

    I also tried:
    Code:
    function ("Long \
        String");
    But for some reason the backslash seems to introduce extra characters into the string and causes my function to fail.

    I'm sure there has got to be a way to do this.

    Let the compiler do the concatenation for you:
    Code:
    function("Long "
             "String");
    This relies on the fact that adjacent string literals are combined into a single string literal, and that whitespace is not significant in this context.

If they do, I ask them to find the smallest example that exhibits the problem and send me that. Mostly, they then find the error themselves. "Finding the smallest program that demonstrates the error" is a powerful debugging tool.
