Problem with if Comparison

		cout<<"\n";

}

The compiler is ignoring the if statement and I can't find why

Which if statement? If you could make the smallest compilable example that demonstrates the problem and tell is exactly what is happening and what you would expect to happen, that would be very helpful.
