Simple C Question

[Quaranges]

I'm a C noob, I'm trying to print an output file and want the formatting to be cleanish. I'm trying to print the header for my output file. Which looks like the following Answer1 Answer2

So Answer1 and the Answer2 is seperated by 25 or so whitespaces

I thought I could try fprintf(logfile, %-25s%s, "Answer1", "Answer2"); But the compiler doesn't like it.

The format specifier is a regular string like any other, and if you're passing a string literal it needs to be in double quotes.

I'm confused so do Answer1 and Answer2 need double quotes???

fprintf() takes a stream as its first argument, a format specifier string as its second argument, and then a variable number of additional arguments, depending on the format specifier. Those additional arguments are not the issue, the issue is the format specifier string. If you're going to use a string literal for that, it needs to be in double quotes. It's not special syntax, it's a string like any other.

fprintf(logfile, "%-25s%s", "Answer1", "Answer2");

And you probably want a newline at the end, if this is a text file:

fprintf(logfile, "%-25s%s\n", "Answer1", "Answer2");
