#include <iostream>
using namespace std;
int main()

{
   char response;

   cout<<"You enter a dark hallway deep under ground..."<<endl;
   cout<<"/////////////////////////////////////////////"<<endl;

 {
    cout<<"Your flashlight begins to flicker, would you like to continue or go back?"<<endl;
    cout<<"/////////////////////////////////////////////////////////////////////////"<<endl;
    cin>>response;

    if (response == 'go back')
{
      cout<<"The door you came from is blocked, you must continue..."<<endl;
      cout<<endl;
     {
      cout<<"You continue walking for some time, you soon reach a split..."<<endl;
      cout<<"Will you go left or right?"<<endl;
      cin>>response;
     }
       if (response == 'left ')
      {
          cout<<"You walk down the left side only to find a dead end, and return to where you came from..."<<endl;
          cout<<"/////////////////////////////////////////////////////////////////////////////////////////"<<endl;
      }
     }
    }
   }


Whenever i compile this program it registers my if statement, and when i type in the response it dosent register and closes my program how could i fix this?

A char is just that - one character, like 'a' or '@'.
You are trying to get the user to enter a specific response, which requires multiple characters, otherwise known as a string.

Solution: Use std::string instead.

Also, the >> operator won't work with spaces, so you'll have to use getline() instead.

Notice the double quotation marks as opposed to the single quotes.

        cout<<"You continue walking for some time, you soon reach a split..."<<endl;
        cout<<"Will you go left or right?"<<endl;

OHHHH, thanks very much i didnt know that char was only used in a single character type thing... Thanks for the help!!
Ganado (6792)
Yep you're welcome

Okay so i put what you had entered and its giving me some bogus errors:
||=== Build: Debug in RolePlayTypeGame (compiler: GNU GCC Compiler) ===|

TarikNeaj (2580)
A good programming practice is instead of using namespace std; explicitly saying std::

for example.
 
 
std::cout << "Hello World!" << std::endl;


You can read all about why on google.
YvngSavage (61)
So, what you saying is that i just need to use std:: instead of using namespace std; and it should be working?
TarikNeaj (2580)
Yes. cout, endl and cin are part of std:: (don't forget the cin inside the getlines).

If it for some reason does not, please post your new code and new errors and I'll take a look :)

    getline(std::cin, response);

        {
            std::cout<<"etc"<<std::endl;
        }
    }
}

its now working thanks very much
Ganado (6792)
What Tarik said is true and a good practice, but either way, my code should have compiled. Are you sure you copied the first line, #include <iostream> ? Your errors would suggest that you didn't.

Edit: Saw your post, glad it's working.

You can read what the errors are telling you and try to understand them, they tell you where the problem is.

To avoid them in the first place, since they are silly mistakes, is just to be more careful.

For every opening bracket there must be exactly one closing bracket. Lines of codes need to end with semicolon aswell.

i tried to add the '}' and these are what i got, theres no missing ';' as it says many times in the errors above

sorry for the inconvenience before hand

Your errors are very obvious and Ive pointed most of them out. Your curly braces are out of place, look through your code carefully.
YvngSavage (61)
You are right Tarik, i resolved almost all the errors, when i went to compile im now getting :



||=== Build: Debug in RolePlayTypeGame (compiler: GNU GCC Compiler) ===|

        std::cout<<"You continue walking for some time, you soon reach a split..."<<std::endl;
        std::cout<<"Will you go left or right?"<<std::endl;
        getline(std::cin, response);

        if (response == "left")
    }
        {


Why is there a closing bracket right after you make an if statement? There should be an opening bracket after that.

If statements look like this 

1
2
3
4
 
if()
{

}


Which means your brackets are misplaced.

Your entire program is outside your main. Get it back in there :D
YvngSavage (61)
What do you mean its outside my main?
TarikNeaj (2580)
I mean it is literally outside of main.

int main()
{
    //Here is inside main
}

//Your program is here


I'll only advise you one more time. Please learn how to debug, and take a good look at your program, you won't learn otherwise.
