This is an if block

This is _not_ an if test.

This line will be executed every time

> else(integer1 % 2 !=0);
> std::cout << "Your number is odd.\n";

The two lines above should be an if or an else block.  Since you've
already done an "is integer1 even" test above, you can then just do:

else {
 std::cout << "Your number is odd.\n";
}

because that will only happen if the "is integer1 even" test fails.
