Thread: Problem with ! function

Im having a problem with this function. I'm trying to make a simple program to test it out (Cause i just started learning C++ Yesterday) But it keeps messing up. Help!

Heres the program

Code:

#include <iostream>

using namespace std;

int main()
{
    int number;
    
    cout<<"Please enter in 5: \n"; 
    cin>> number;
    cin.ignore();
    
    if ( number == 5 ) {
         cout<<"Yay. You entered in 5\n";
         }
    if ! ( number == 5); {     //HERES THE PROBLEM
         cout<<"THAT IS NOT 5. YOU LOSE.\n"; 
         }
         cin.get();
}

I'm just a beginner, so im not good at trouble shooting.

So the thing behind an if statement must be in parentheses. "!(number==5)" is not in parentheses.

Ok...i gotta be more careful with these ;

if ( number != 5 ); was the old one,
if ( number != 5 ) is the new one. THE ; RUINED IT.
Alright. Fixed it. So...Yeah.

Also, id doesn't have to be. Theres variations. I used this formula to compare:
!=....Yeah. its different from the normal == but it is easier if you ask me. Less code by 2 of these "
Still learning...so i may make more mistakes.

Since you were playing with the negation operator, it may be worth pointg out that this also would have worked:

Code:

if (!(number == 5)) {
    cout << "THAT IS NOT 5. YOU LOSE.\n" ;
}
