Question

I am using assertion macro from assert.h I have defined lambda to perform assertion checking.

int val1 = 0;
int val2 = 1;

const auto check = [val1,val2]()-&         


        

Answer 1

The preprocessor is very simple, it sees all commas as argument separators.

So you can't use a macro if you pass in anything with a comma as argument to the macro.
