2.9. Primer Summary

What we've covered so far shouldn't be too hard. If you'd like to experiment, try writing similar programs that output a few lines. Split your program into a couple of functions and divide them into two files.

Always enable GCC's warnings when compiling your program. Warnings mean your code is unclear or incomplete, GCC will guess at the correct meaning and will usually get it right but you should not rely on this. Looking at and correcting the warnings will help you get used to the language. Most warnings are accompanied by the line number where the problem is. If you can't see anything wrong with that line check the line above it; if a statement is incomplete GCC won't notice that it is an error until it encounters the beginning of the following statement. Don't forget your semi-colons.
