[prog] Re: more C++

[wolf]

Okay, I'm starting to get really confused : )
This is my program now and it compiles without an error, when you type 
in an odd number you get a correct response but when
you enter in an even number it prints out both the number is odd and 
the number is even. Why isn't there any error message and
what did I do incorrectly that it only works for odd numbers?



#include <iostream>


int main()


{

int integer1;

std::cout << "Enter a whole number\n";
std::cin >> integer1;

if(integer1 % 2 == 0) {

std::cout << "Your number is even.\n";
}

else(integer1 % 2 !=0);


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



return 0;
}
