Did you try looking it up in your C documentation?
Try this as a place to start... C preprocessor - Wikipedia, the free encyclopedia
Basically it does what it says it does, it concatenates two values.
If you wrote
int _CONCAT(myvar,123);
The compiler will see
int myvar123;
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
hey, thank you.
