Question

Write a C++ console application to simulate a guessing game. Generate a random integer between one and 100 inclusive. Ask the user to guess the number. If the user’s number is lower than the random number, let the user know. If the number is higher, indicate that to the user. Prompt the user to enter another number. The game will continue until the user can find out what the random number is. Once the number is guessed correctly, display a message to tell the user his/her guess is correct. Also, display the number of guesses that lead the user to the correct number. Label your output properly. Do not accept numbers outside the range; and do not count invalid numbers as an attempt. Ask the user if they want to continue the game. If so, generate another random number and allow the user to play again. When the user decides to stop, end the program.

C++ Code :

#include<iostream>
#include<stdlib.h>            // for using rand() and srand()
#include<ctime>           // for using time()
using namespace std;
int main()
{
   while(true)               // iterating till user wants to play the game or until user exits the game
   {
       srand(time(NULL));               // for generating different random numbers everytime
       int value = rand() % 100 + 1;               // generating random numbers between 1 and 100 inclusive
       cout << "\nRandomly generated number is : " << value << "\n";           // printing Randomly generated number
      
       int count = 0;           // for counting the total number of guesses
       while(true)               // iterating until user guesses the correct number
       {
           int x;           // for storing user input of guessed number
           cout << "\n\nNow, Guess a number : ";           // asking for the input of guessed number
           cin >> x;               // taking input of guessed number by user
           if(x<1 && x>100)               // if the guessed number if out of range
           {
               cout << "\nGuessed number is of outside the range ! Please try again";
               continue;           // continue for asking again input of guess number
           }
           if(x > value)           // if the guessed number is greater than the Randomly generated number
           {
               cout << "\nGuessed number is greater than the Randomly generated number";           // printing the required messgae
               count++;           // incrementing the count of guesses
               continue;           // continue for asking again input of guess number
           }
           else if(x<value)           // if the guessed number is smaller than the Randomly generated number
           {
               cout << "\nGuessed number is smaller than the Randomly generated number";           // printing the required messgae
               count++;           // incrementing the count of guesses
               continue;           // continue for asking again input of guess number
           }
           else            // if the guessed number is correct and equal to the Randomly generated number
           {
               cout << "\nCongrats! Guessed correctly";           // printing the required messgae
               count++;               // incrementing the count of guesses
               cout << "\n\nYou have lead " << count << " number of guesses to the correct number.";           // printing the total number of guesses lead
               break;               // breaking out from the loop
           }
       }
      
       char choice;               // for storing the user's choice whether user wants to play the game again or exit the game
       cout << "\n\nDo you want to play this game again (y/n) ? ";           // asking for the input of user choice
       cin >> choice;           // taking input of user choice
      
       if(choice=='n')               // if user wants to exit the game
       {
           cout<<"\n\nThanks for playing the game, Bye\n";               // printing the required messgae
           break;               // and breaking out of the while loop for exiting the game
       }
   }
}
