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

Answer 1

Well, if the code that needed to be disabled once or twice before finalizing, I prefer to use hotkeys provided by IDE to comment that code out, and later comment in. Yes, I need to select the code block first, but I prefer not to include one more debugging variable/preprocessor directive/if statement every time I need to disable a part of code. This happens to be most of the time.

If, on the other hand, I need to repeatedly switch between 2 code blocks to find the right thing, then I use a if (0) / if (1) to disable/enable code block.

[code block 1]

Later

if (0)
{
    [code block 1]
}
else
{
    [code block 2]
}

Answer 2

#if 0
...disabled code here
#endif
