Say I had a library called libfoo which contained a class, a few static variables, possibly something with 'C' linkage, and a few other functions. Now I have a main program which looks like this: int main() { return 5+5; } When I compile and link this, I link against libfoo. Will this have any effect? Will my executable increase ...

Hello, I have a problem that consist in comparing boolean expressions ( OR is +, AND is * ). To be more precise here is an example: I have the following expression: "A+B+C" and I want to compare it with "B+A+C". Comparing it like string is not a solution - it will tell me that the expressions don't match which is of course false. Any i...

I have not used Unit Testing so far, and I intend to adopt this procedure. I was impressed by TDD and certainly want to give it a try - I'm almost sure it's the way to go. Boost looks like a good choice, mainly because it's being maintained. With that said, how should I go about implementing a working and elegant file-structure and proj...
