Question

Write a C++ code for this question- Write a program with a method that plays the guess a number game. The program should allow the user to pick a number between 1 and 1000 in his head. The method should guess the user's number in a minimal amount of attempts. The method should ask the user "is the number greater than or less than the number    " and the program gives a particular number. The user in some way just inputs (higher or lower) or (greater than or less than). There also has to be a way for the user to say the number has just been guessed. Of course, the user cannot answer incorrectly or change the number midstream. Note - if written efficiently, the method should be able to guess any number in 10 or less attempts. (This question has me at a loss for words and I have no idea how to do this. Please try to do it as basic as possible so I can study and learn from this! I greatly appreciate the help!)

Answer 1

CODE:

#include <iostream>

using namespace std;

// defining method guess

// with two parameters low and high

int guess(int low, int high){

// delcaring string

string reply;

// if high is greater than low

  if(high>=low){

// finding mid number of high and low

    int avg = (high+low)/2;

// asking user whether it is the number or not

    cout << "Is " << avg << " the guessed number? (yes/no)" << endl;

    cin >> reply;

// if it is the number then returning number

    if(reply.compare("yes")==0) return avg;

    // if mid number is not the number

if(reply.compare("no")==0){

// asking user whether the number is greater or lesser

      cout << "Is the number `greater` or `lesser` than the number " << avg << endl;

cin >> reply;

// if greater then calling method guess

// with new arguements

      if (reply.compare("greater")==0) return guess(avg, high);

      // else calling function with lesser than arguements

return guess(low, avg);

    }

  }

  return -1;

}

int main() {

cout << "Pick a number between 1 and 1000 in your head." << endl;

int num = guess(1,1000);

cout << "Number is " << num << endl;

}

SAMPLE OUTPUT: (i guessed 400)
