Confusing format specifiers

Question

Can anyone explain in detail about %f format specifier in C and all it's variations, because it's confusing to me as I'm new to C.

1. if I write %5.2f ... does 5 matters here?
2. if I add negative sign %-5.2f does it make any change?

and some more clarity if someone can give I'd be glad

Answer 1

5 tells it that the number should take up at least 5 characters. The minus means left alignment. You can find some info on the following web site...
