For given SQUARE macro definition, what value will be shown on a screen after executing next code:

#define SQUARE(x) ((x)*(x))
int m = 4;
SQUARE(++m);
std::cout << r;

Sixteen
Twenty-five
Thirty-six

Explanation

During the #define directive execution, text substitution of each symbol "X", that was found in the body of the function, to the current value of the variable "m" is performed. Thus, after such type of replacement current, the value of "m" is increased by 1.
