I am looking for ways to visualize the effects of #define's - For example that code not seen by the compiler is shown in a different color.
I have a C++ macro-based DSL that defines a macro like this:This is for use like:Which expands to:(When C++20 concepts are enabled, this expands to a real requires clause.)
I ran into this problem earlier today. In the following code:When compiled and executed with:It prints out 1 instead of 0, meaning that the 2 Ts in Helper<int> and Helper<bool> are the same type, which makes me wonder:
I am developing a platform layer for my application in C/C++.I would like to#define WINDOWS // on Windows machines
My code only makes sense if MY_CONST > OTHER_CONST. How can I guarantee this with the preprocessor? Is there any command like this?
I just noticed that I can use / to extend the single-line comment to the next line, similarly to doing so in pre-processor directives.
Below is the small program:And the output of the program is:Can anyone help me to understand why the sizeof(max) is 4 bytes?
