#include <cstdio>

enum COLOR { Red, Green, Blue };

void SetColor( COLOR Val )
{
    if( Val == Red )
         printf( "Changed to Red" );
   
    if( Val == Green )
         printf( "Changed to Green" );
   
    if( Val == Blue )
         printf( "Changed to Blue" );
   
}

int main()
{
    SetColor( Blue );
}
