Number Guessing Game in C++

Number Guessing Game in C++

In this article, we will build a simple Number Guessing Game in C++. It’s a game in which the player has to guess a secret number in a range that is generated by the computer and upon a wrong guess by the player, the game will give hints to the player to guess the correct number. This will be a console game so even if you have little knowledge of C++, you will be able to follow up and build this game easily.

Features

The player can choose the number of rounds he wants to play the game
After finishing each round the current score is updated and once all the rounds are completed the high score is updated and shown on the screen.
If the player guesses the correct number on the first try, he gets 10 points, If guessed on the second try then 5 points, if guessed on the third try then 3 points, and if guessed after the third try then only 1 point.

Code for Number Guessing Game in C++

We will use Code::Blocks IDE to develop this application. Open the Code::Blocks IDE and create a new project with the name guessthenumber, now in the main.cpp file paste the following code and run it.

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

    system("color CF"); //This gives the terminal a color and the text on the screen
    system("title GuessTheNumber @copyassignment"); //This sets the text on the terminal
    int user_input,secret_num,c=0,wrong_attempts=0;
    int curr_score=0, max_score=0;
    int number_of_rounds;
    int choice;
    cout << "\t\t\t<==================================================================>" << endl;
    cout << "\t\t\t|                 Welcome to the number guessing Game              |" << endl;
    cout << "\t\t\t<==================================================================>" << endl;
    cout << endl << endl << endl;
    cout << "\t\t\tchoose from below options" << endl;
    cout << "\t\t\t [1] Know Game Rules" << endl;
    cout << "\t\t\t [2] Play the game" << endl;
    cin >> choice;
    if(choice == 1){
        system("cls");
        cout << "\t\t\t<==================================================================>" << endl;
        cout << "\t\t\t|                 Welcome to the number guessing Game              |" << endl;
        cout << "\t\t\t<==================================================================>" << endl << endl << endl;
        cout << "\tChoose the number of rounds you want to play from 1-10" << endl;
        cout << "\tIn each round, you have to guess the secret number correctly" << endl;
        cout << "\tIf you guess the secret number in first attempt, you get 10 points" << endl;
        cout << "\tIf you guess the secret number in second attempt, you get 5 points" << endl;
        cout << "\tIf you guess the secret number in third attempt, you get 3 points" << endl;
        cout << "\tIf you guess the secret number in after third attempt, you get only 1 point" << endl;
    }
        cout << endl << endl;
        char ch;
        do
        {
            cout << "\t Please enter number of rounds you want to play this game (1-5)" << endl;
            cin >> number_of_rounds;
            curr_score = 0;
            wrong_attempts = 0;
            // this loop run for the number of rounds the user wants to play
            for(int i=0; i<number_of_rounds; i++){
                secret_num=rand()%10+1; // generate a random secret number in the range 1-10

                // until the user doesn't find the right answer keep on asking and checking
                while(secret_num != user_input)
                {
                    cout<<"\t Enter your guess between 1-10 "<<endl;
                    cin >> user_input;
                    cout<<endl;
                    if(user_input < secret_num){
                        cout << "\t Your guess is low, guess higher!!!" << endl;
                        wrong_attempts++;
                    }
                    else if(user_input > secret_num)
                    {
                        cout<<"\t Your guess is high, guess lower!!!"<<endl;
                        wrong_attempts++;
                    }
                }

                //when the user has guessed it right, check how quickly the number was found and give points accordingly
                cout<<"\t Congratulations your guess is correct"<<endl << endl;
                cout<<"\t You guessed wrong numbers " << wrong_attempts << " times" << endl << endl; //show how many times the number was guessed wrong

                //if there is next round still remaining then show message
                if(i!=number_of_rounds-1){
                    cout << "\t Let's start next round" << endl;
                }
                cout << endl << endl;
                    if(wrong_attempts == 0){
                        curr_score = curr_score + 10;
                    }
                    else if(wrong_attempts == 1){
                        curr_score = curr_score + 5;
                    }
                    else if(wrong_attempts == 2){
                        curr_score = curr_score + 3;
                    }
                    else{
                        curr_score = curr_score + 1;
                    }
            }

            //set the high score if it's greater than previous score
            if(curr_score > max_score){
                max_score = curr_score;

Conclusion

I hope this article on Number Guessing Games in C++ could help you learn something valuable. Building these types of small games can help you get good at logic building and learn a language faster. You should try to tweak the code here and there and see how the whole program is working.
