# Building a Number Guessing Game in C++

In this C++ tutorial, we are going to learn how to make a number guessing game in C++. This particular game is called number guessing game in which you have to guess the number and you will be given a certain number of chances. If you guess the right number you will win otherwise you will lose. This game is also known as guess the number game in C++. Let’s begin our tutorial.

**Algorithm:**

- First of all, we will generate a random number using
**rand()**function in**C++**. - Then we will take input from the user if input matches to the random number, the user will win and the game will terminate.
- Otherwise, there will be a certain number of chances until which the game will run. If the user still wasn’t able to get the right guess he/she will lose.
- One can use his own logic regarding the range of number and number of turns.

## Number Guessing Game in C++

Source code in “.cpp” file:

// Number guessing game in C++ #include<bits/stdc++.h> using namespace std; int main() { int n,i; int number; // Generating different random numbers each time game will run srand(time(0)); //Generating random numbers number=rand()%51; cout<<"Guess a number between 1 and 50, only 5 turns will be allowed: "; for(i=0;i<5;i++) { cin>>n; if(number==n) { cout<<"\nCongrats, you have guessed the right number which is, "<<number; cout<<"\nNumber of turns you have used: "<<i+1; break; } else if(number>n) { cout<<"\nYour guess is lower than right number, Turns left: "<<5-(i+1); if(5-(i+1)>0) { cout<<"\nTry again, entering a number higher than previous: "; } } else if(number<n) { cout<<"\nYour guess is higher than right number, Turns left: "<<5-(i+1); if(5-(i+1)>0) { cout<<"\nTry again, entering a number lower than previous: "; } } } if(i==5) { cout<<"\n\nSorry, you failed to guess the right number."; cout<<"\nThe right answer is: "<<number; } return 0; }

Output:

Guess a number between 1 and 50, only 5 turns will be allowed: 30 Your guess is higher than right number, Turns left: 4 Try again, entering a number lower than previous: 20 Your guess is lower than right number, Turns left: 3 Try again, entering a number higher than previous: 25 Your guess is lower than right number, Turns left: 2 Try again, entering a number higher than previous: 28 Congrats, you have guessed the right number which is, 28 Number of turns you have used: 4 -------------------------------- Process exited after 31.05 seconds with return value 0 Press any key to continue . . .

### Key points of this Game:

**rand() function**is used to generate random numbers.**srand() function**is used to generate different random numbers each time game will run.
