I'll see what gcc complier options I should use to detect the use of declared variables that are not initialized
The flag you are looking for is -Wall. Please fix all the warnings that it may raise. Generally speaking, it is also much easier to ensure your variables are initialized if you restrict them to the smallest scope possible. That is, declare the variable immediately before you use it. If you only use it within a loop, then only declare it inside that loop. If you only use it in an if branch, then only declare it inside that branch.
