# 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;
}
system("cls");
cout << "\t\t\t You have completed all the rounds" << endl;
cout << "\t\t\t Your current score is: " << curr_score << endl;
cout << "\t\t\t Highest score: " << max_score << endl << endl << endl;
cout<<"Do you want to play again y/n";
cin >> ch;
cout<<endl;
if(ch !='n' && ch !='y'){
cout << "\tWrong Input, Please enter y/n" << endl;
}
system("cls");
cout << "\t\t\t<==================================================================>" << endl;
cout << "\t\t\t|                 Welcome to the number guessing Game              |" << endl;
cout << "\t\t\t<==================================================================>" << endl;
}while(ch!='n');

}```

## 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.
