I need to make a "Guessing game" but I'm stuck because I'm not sure if this is the right way to make it, since it's so hard to actually find the number I'm thinking of when playing the game.

#include <iostream>

#include <string>

using namespace std;

int main ()

{

int guess;

int n=500;

cout<<"Think of a number from 1 to 1000."<<endl;

cout<<"The number is : 1. 500"<<endl;

cout<<"2. Bigger than 500"<<endl;

cout<<"3. Smaller than 500"<<endl;

cin>>guess;



while(n<=2000)

{

    if(guess==1)

    {

        cout<<"The computer has guessed the number!";

        break;

    }

    else if(guess==2)

    {

        n+=n/2;

        cout<<"The number is :n1."<<n<<endl;

        cout<<"2. Bigger than "<<n<<endl;

        cout<<"3. Smaller than "<<n<<endl;

        cin>>guess;

    }

    else if(guess==3)

    {

        n-=n/2;

        cout<<"The number is :n1."<<n<<endl;

        cout<<"2. Bigger than "<<n<<endl;

        cout<<"3. Smaller than "<<n<<endl;

        cin>>guess;

    }

  }

}

I can't seem to find a better way to make the game. The number always goes over 1000 so I had to set the while to under 2000 for it to work.

It would be good if I could set the n+=n/2 formula so that it splits the last number that was the n variable. For example : 500+(500/2), then 750+(250/2), then 875+(125/2) (not sure how it would continue when the 125 will get split into 62.5) or the same with the n-=n/2.

#include <iostream>

using namespace std;



int main()

{

    int guess;

    int min = 0, current = 500, max = 1000;

    cout << "Think of a number from 1 to 1000." << endl;

    cout << "The number is : 1. 500" << endl;

    cout << "2. Bigger than 500" << endl;

    cout << "3. Smaller than 500" << endl;

    cin >> guess;

    while (current <= 2000)

    {

        if (guess == 1)

        {

            cout << "The computer has guessed the number!";

            break;

        }

        else if (guess == 2)

        {

            min = current;

            current = (min + max) / 2;



            cout << "The number is :n." << current << endl;

            cout << "2. Bigger than " << current << endl;

            cout << "3. Smaller than " << current << endl;

            cin >> guess;

        }

        else if (guess == 3)

        {

            max = current;

            current = (min + max) / 2;

            cout << "The number is :n." << current << endl;

            cout << "2. Bigger than " << current << endl;

            cout << "3. Smaller than " << current << endl;

            cin >> guess;

        }

    }

}

This should work. the min and max effectively restrict the domain after each guessing.
