Simple Int operations

#include <iostream> //For std::cin, std::cout
using namespace std;

int main()
{
 cout << " a = ? ";
 int a{};
 cin >> a;

 cout << " b = ? ";
 int b{};
 cin >> b;

 cout << '\n';
 cout << " a + b = " << (a+b) << '\n';
 cout << " a - b = " << (a-b) << '\n';
 cout << " a * b = " << (a*b) << '\n';
 cout << " a / b = " << (a/b) << '\n';
 cout << " a % b = " << (a%b) << '\n';
}
