Question

Write a program that plays a guessing game where the computertries to guess a number picked by the user. The program asksthe user to think of a secret number and then asks the user asequence of guesses. After each guess the user must reportwhether it is too high, or too low, or correct. The programshould count the number of guesses. (hint: Maintain HighestPossibleand LowestPossible variables and always guess midway between thetwo. This is called a binary search.)

The Program should look similar to:

     Think of a number between 1 and 100 andthe press enter

       Is the number 50(C-correct,L-low, H-High)   H

       Is the number25(C-correct, L-low, H-High)   H

       Is the number 13(C-correct,L-low, H-High)   L

       Is the number 19(C-correct,L-low, H-High)   C

       It took you 4 guesses.

      Do you want to play again?n
