'isEven' : must return a value is the error I am getting. I dont understand because it is returning a value?

#include <iostream>
#include <cmath>

using namespace std;

int number;
string Even;
string Odd;

int isEven( int x )
{
if (( x % 2) == 0 )
cout << "Even";

else
cout << "Odd";
}

int main()
{
cout << "Please enter number";
cin >> number;

cout << isEven( number );

}

int isEven()

The function promises to return an integer.
You are not returning anything.

change the return type to void.

[kalicha]

you can change it to void or just return 0.

void isEven( int x )
{
    if (( x % 2) == 0 )
        cout << "Even";
    else 
        cout << "Odd";
}

int main()
{
     cout << "Please enter number";
     cin >> number;
     isEven( number );
 
    return 0;
}
