For given macro definition, what will be printed to the console?
#define Some_operation(x, y) ((x) + (y) - 1) / (y)

int main()
std::cout<< sizeof Some_operation(1,2);
The precompiler will generate the following code: std::cout << sizeof ((1) + (2) - 1) / (2);
Since sizeof operator has a higher priority, it will be evaluated first, and then the result will be divided by 2, hence, the final result is 2.
