Why this code isn't working? (C++)

Question

Code:

#include <iostream>
using namespace std;

int main() {

int a;
cout << "enter a number";
cin >> a;

cout <<" " << a << endl;

int b;
cout << "enter anther number";
cin >> b;

cout << " " << b << endl;

int c=a + b;
int d=a - b;
int e=a * b;
cout<< "The sum is "<<c, d, e;

return 0;
}

This is is a calculator the problem is that the multiplication isn't working i dont know what
Help please

Answer 1

last cout is done wrong.
It should be cout<< "The sum is " << c << " "<< d << " " << e;

The compiler cuts everything after comma, in newer compilers it shows error.

Answer 2

@R4Z7 now you see the difference between your code and @Mara's one? I will point the differences:
-Variables are initialized
-Last cout has changed to the one that I told you about.

Answer 3

What is it c++11?
