You can use '#' sign to get exact name of an argument passed to a macro:
#define what_is(x) cerr << #x << " is " << x << endl;
int variable = 376;
what_is(variable);
// prints "variable is 376"

x += c++

int main ()
{
  int a, b=3;
  a = b;
  a+=2;             // equivalent to a=a+2
  cout << a;
}
