how to add a counter

Question

I am confused on how to add a counter to my code - I'm writing a 2 player number guessing game and I want to add the number of guesses it took to satisfy the program.

This is what I've got so far:

#include <iostream>
#include <cstdlib>
#include <ctime>

int main()
{

    int x;
    int  guess;

    std::cout << "Enter the number for the player to guess.";
    std::cin >> x;

    do
    {
        std::cout << "Enter your guess.";
        std::cin >> guess;
        if (guess > x)
            std::cout << "lower\nEnter your guess.\n";
        else if (guess < x)
            std::cout << "higher\nEnter your guess.\n";
        else
            std::cout << "You guessed it!\n";
    } while (guess != x);

    return 0;
}

You have a bug. If the player enters the incorrect number, "Enter your guess" will be printed twice. — NobodyNada, Apr 19 '15 at 03:21

You just need to add a variable and increase it each time you loop, like so:

int guesses = 0;

do
{
    guesses++;
    std::cout << "Enter your guess.";
    std::cin >> guess;
    if (guess > x)
        std::cout << "lower\nEnter your guess.\n";
    else if (guess < x)
        std::cout << "higher\nEnter your guess.\n";
    else
        std::cout << "You guessed it!\n";
} while (guess != x);

std::cout << "You took " << guesses << " guesses!" << std::endl;

Thanks Kvothe, I have so much to learn, but I'm getting there, two weeks ago I felt like a hacker because I log'on to a command line server, lol... – Sneha Apr 18 '15 at 19:26

  #include <iostream>
#include <cstdlib>
#include <ctime>


 int main()

{

int x;
int  guess;

std::cout << "Enter the number for the player to guess.";
std::cin >> x;
int count = 0;    

  do
{
    std::cout << "Enter your guess.";
    std::cin >> guess;
    if (guess > x)
        std::cout << "lower\nEnter your guess.\n";
    else if (guess < x)
        std::cout << "higher\nEnter your guess.\n";
    else
        std::cout << "You guessed it...";
    count++;
  } while (guess != x);
  std::cout << "in " << count << "times" <<endl; 

  return 0;
 }

The count variable will count the number of times the player guess and you can print the count after guess is correct.

Use a variable to store the count of guesses and increment it until the answer matches. :)

#include <iostream>
#include <cstdlib>
#include <ctime>


 int main()

{

int x;
int  guess;

std::cout << "Enter the number for the player to guess.";
std::cin >> x;
int counter=0;
  do
{
    counter++;
    std::cout << "Enter your guess.";
    std::cin >> guess;
    if (guess > x)
        std::cout << "lower\nEnter your guess.\n";
    else if (guess < x)
        std::cout << "higher\nEnter your guess.\n";
    else
        std::cout << "You guessed it!\n";
  } while (guess != x);
std::cout<<"You have guessed "<<counter<<" times for correct answer"<<endl;
  return 0;
 }

    int x;

    std::cout << "Enter the number for the player to guess.";

            std::cout << "You guessed it!\n";
        ++counter; //increase it each time a guess happened
    } while (guess != x);

    //print the count of guesses
    std::cout << "Took you " << counter << " guesses!" << std::endl;

    return 0;
}
