Question

I am trying to print out to console using a macro the variable name for display members value while debugging ( logging ).
How to do that? I tried the following but it doesnt’ work.

#define MY_PRINT(x) std::cout << "'x'=" << x << std::endl;

int main(){
   int my_variable=3;
   MY_PRINT( my_variable );
   // I would like to print to console
   // 'my_variable'=3
}

Auch… I found the solution.

I should write the macro like this

 #define MY_PRINT(x) std::cout << #x"=" << x << std::endl
