Simple ways to disable parts of code

Question

This isn\'t a typical question to solve a specific problem, it\'s rather a brain exercise, but I wonder if anyone has a solution.

In development we often need to disable

If you're doing checks at compile time, you can use Gigi's answer, which will conditionally not compile sections of code. Note that the preprocessor has no knowledge of variables, or sizeof, or other things handled by the compiler (so using something like 4 == sizeof(int) will not fly)

If you want to compile in little bits of debugging code that should not ever get run, you can use regular conditional statements, like such

bool debugging = false;

// banana banana banana

if (debugging)
{
    // do a bunch of stuff here
}

You can then use a debugger to access the skipped section by assigning debugging to true.
