Question

The error I’m getting is error: expected ' ; ' before ' { ' token

I tried fixing the code by adding ; after if (thisisanumber==5) as well as after else (thisisanumber!=5). While this solves the first error it creates another error that says error: ' else ' without a previous ' if '. I’d really love to know what error I’ve made in writing the code, thanks.

Here is my code:

#include <iostream>

using namespace std;

int main()
{
    int thisisanumber;

    cout<<"Whats the Password?: ";
    cin>> thisisanumber;
    cin.ignore();
    if (thisisanumber==5) {
        cout<<"You've discovered the password! Wow, you're a genious you should be proud./n";
        }
    else (thisisanumber!=5) {
        cout<<"You've failed in knowing the password and therefore cannot enter, leave and do not come back. Goodbye!/n";
        }
    cin.get();
}

You don’t need another condition as there are only two cases – just use else { ... } and it will catch all cases in which thisisanumber==5 is false.

The structure of an if statement is:

if (condition) { ... }

else if (another condition) { ... }
// ... more conditions

else { ... all cases in which no previous condition matched end up here  ... } 

… but the else if and else parts are always optional.
