do while loop is skipping

[rej3kt]

Hi all my do while loop is skipping one of my questions that i'm trying to ask.
It is skipping the manx cat tail question, the only other prob is that it is not
assigning a value to the restart variable so it's not recognisin it on the end of my do loop, any help would be great because I just can't seem to figure this out!

#include <iostream.h>
#include <windows.h>
#include <string.h>



int main()

{
    int count;
    char guess[30];
    char name[30];
    char password[30]= "Meow!";
    int counter;
    
    char restart;              // variable for restart of test
    int answer1int;   
    int answer2int;            
    char answer1chararray[30]; 
    char answer1chararray_answer[30]= "Tails";
    char answer2chararray[30]; 
    char answer2chararray_answer[30]="Venus";
    char answer1char;
    char answer2char;    
    int correct = 0;
    int incorrect = 0;
        
     for(count=10; count >= 1; count--)
  {
    
      cout << count << endl;
      Sleep(5);
  }
  
  
  
  cout<<"Please Enter Your Name: "<<endl;
  cin.getline(name,30);
  
  cout<<"Now Please Enter The Password"<<endl;
  cin.getline(guess,30);
  
  if((!strcmp (guess, password)))
  {
              cout<<"Gratz...";
              
  }
              
              else
              {
                  // Compares 2 character arrays as long as they end in null \0 which char strings do, only returns boolean value.
                  while ((strcmp (guess, password) != 0) ) //hence why not equal is there, == does not work apparently.

                  {cout<<"Please Enter The Correct Password"<<endl;
                   cin>>guess;}

  cout<<"Would you like to restart the quiz? Please enter Y/N";
  cin>>restart;
  
}while(restart == 'y' || 'Y');



  
 

 
    system("PAUSE");
    return 0;
    
}

}while(restart == 'y' || 'Y'); should be }while(restart == 'y' || restart == 'Y');

[rej3kt]

ahhh yeah thanks, was gettin towards the end of the day and I was getting a bit frustrated.


Now to figure out why the program is skipping the "Tails" question

[Bazzy]

You mean that on line 152?
Try flushing cout before getting input

[rej3kt]

flushing cout?

Whatcha mean flushing? Hav't covered it yet.


It works if I place it at the beginning of the code but not where it is, so i'm really perplexed.

[Bazzy]

flush makes cout display the last inserted characters, see
http://www.cplusplus.com/reference/iostream/ostream/flush/
http://www.cplusplus.com/reference/iostream/manipulators/flush/

( endl already flushes )

[rej3kt]

cheers mate will have a look, appreciate the help.

[rej3kt]

if endl; ahh right I slightly learned in passing about flushing the output buffer <<endl; does and \n doesn't right? Then i've already flushed at the end of it and before, I always use <<endl; at the end of cout if I want a new line.

[Bazzy]

Yes, but you don't have endl on the last line so you should flush it. endl adds a \n and flushes
Just try calling flush after line 152 and before line 153 to see if this solves the problem

[rej3kt]

Oh yeah all that works after you corrected me the first time, it's line 95 thats skipping, i'm sure I can see it coming up but skipping v.fast.

[Bazzy]

Is it skipping the question to be displayed or the input being read?

[rej3kt]

got it sorted by adding another cin.getline underneath it =)
