Question

Part 1

Write a program that plays the other side of the game "I'm thinking of a number"

Accuse the player of cheating if the player doesn't say y even though your program is sure that it has the correct number .

PT[154]% ./a.out
Think of a number between 1 and 100.
I will guess the number, then tell me if my guess is
too high (enter 'h'), too low (enter 'l') or correct
(enter 'y' for 'yes').

Is it 50? [(h)igh, (l)ow, (y)es] h
Is it 25? [(h)igh, (l)ow, (y)es] l
Is it 37? [(h)igh, (l)ow, (y)es] l
Is it 43? [(h)igh, (l)ow, (y)es] h
Is it 40? [(h)igh, (l)ow, (y)es] h
Is it 38? [(h)igh, (l)ow, (y)es] y
Yay! I got it!

Answer 1

CODE :

#include <iostream>
using namespace std;
int main(){
cout<<"Think of a number between 1 and 100.";
cout<<"I will guess the number, then tell me if my guess is too high (enter 'h'), too low (enter 'l') or correct";
cout<<"(enter 'y' for 'yes')."<<endl; //all the instructions for the game
int i = 50,l = 0,h = 101; //l and h are lower and higher limits
char ch = 'a'; //variable to store user input
while(ch!='y'){
cout<<"Is it "<<i<<"? [(h)igh, (l)ow, (y)es]"<<endl;
cin>>ch;
if(ch=='y')
cout<<"Yay! I got it!"<<endl;
else if(ch=='h'){ //as number is smaller, it changes the upper limit
h=i;
i=int((l+h)/2);
}
else if(ch=='l'){ //as number is bigger, it changes the lower limit
l=i;
i=int((l+h)/2);
}
else
cout<<"Enter a valid response."<<endl; //to make the game more interactive
if(h == (l+1)){ //if the user is cheating, there must be a difference of one between l and h
cout<<"You are cheating"<<endl;
break;
}
}
}

OUTPUT :

Run 1 :Think of a number between 1 and 100.I will guess the number, then tell me if my guess is too high (enter 'h'), too low (enter 'l') or correct(

enter 'y' for 'yes').
