converting a variable name to a string in C++

Question

I\'d like to output some data to a file. For example assume I have two vectors of doubles:

vector data1(10);
vector data2(10); 
         


        

Answer 1

Slightly adapted from @sarnold's answer, for C++:

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

An example program which uses this:

int main() {
    int foo = 1;
    DEBUG(foo);

    return 0;
}
