Question

Using C++ microsoft visual studios 2013 write a program (with //comments) 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.

Explanation / Answer

Here is the C++ code for the above scenario:

#include <iostream>

#include<time.h>

using namespace std;

int main ()

{

int random;

int num;

int max;

int min;

int outofrange;

int rightguess;

rightguess = 1;

outofrange = 0;

max = 1000;

min = 1;

srand(time(NULL));

cout << "random number: " << rand()%10 << endl;

cout << "Enter an interger that is between 0 and 100: "<< endl;

cin >> num;

while (num != rand()%10)

{

if ( num > rand()%10)

{

cout << num << " is too high" << endl;

max = num - 1;

}

else

{

cout << num << " is too low" << endl;

min = num + 1;

}

cout << "Enter an interger that is between " << max << " and "<< min << endl;

cin >> num;

if (num > max || num < min)

{

cout << "the interger you enter is not within range, enter a number between " << max << " and " << min << endl;

cin >> num;

outofrange = outofrange + 1;

}

else

rightguess = rightguess +1;

}

cout << " It took you " << rightguess << " valid guesses to find the number " << endl;

cout << " You had " << outofrange << " out of range guess " << endl;

return 0;

}
