Rewrite a C++ Program with the given code and instructions: Example 5-6 implements the Number Guessing Game program. If the guessed number is not correct, the program outputs a message indicating whether the guess is low or high. Modify the program as follows: Suppose that the variables num and guess are as declared in Example 5-6 and diff is an int variable. Let diff = the absolute value of (num - guess). If diff is 0, then guess is correct and the program outputs a message indicating that the user guessed the correct number. Suppose diff is not 0. Then the program outputs the message as follows: If diff is greater than or equal to 50, the program outputs the message indicating that the guess is very high (if guess is greater than num) or very low (if guess is less than num). If diff is greater than or equal to 30 and less than 50, the program outputs the message indicating that the guess is high (if guess is greater than num) or low (if guess is less than num). If diff is greater than or equal to 15 and less than 30, the program outputs the message indicating that the guess is moderately high (if guess is greater than num) or moderately low (if guess is less than num). If diff is greater than 0 and less than 15, the program outputs the message indicating that the guess is somewhat high (if guess is greater than num) or somewhat low (if guess is less than num). As in Programming Exercise 15, give the user no more than five tries to guess the number. (To find the absolute value of num - guess, use the expression abs(num - guess). The function abs is from the header file cstdlib.)

Question

Rewrite a C++ Program with the given code and instructions:

Example 5-6 implements the Number Guessing Game program. If the guessed number is not correct, the program outputs a message indicating whether the guess is low or high.

Modify the program as follows: Suppose that the variables num and guess are as declared in Example 5-6 and diff is an int variable. Let diff = the absolute value of (num - guess).

If diff is 0, then guess is correct and the program outputs a message indicating that the user guessed the correct number.

Suppose diff is not 0. Then the program outputs the message as follows:

If diff is greater than or equal to 50, the program outputs the message indicating that the guess is very high (if guess is greater than num) or very low (if guess is less than num).
If diff is greater than or equal to 30 and less than 50, the program outputs the message indicating that the guess is high (if guess is greater than num) or low (if guess is less than num).
If diff is greater than or equal to 15 and less than 30, the program outputs the message indicating that the guess is moderately high (if guess is greater than num) or moderately low (if guess is less than num).
If diff is greater than 0 and less than 15, the program outputs the message indicating that the guess is somewhat high (if guess is greater than num) or somewhat low (if guess is less than num).

As in Programming Exercise 15, give the user no more than five tries to guess the number.

(To find the absolute value of num - guess, use the expression abs(num - guess). The function abs is from the header file cstdlib.)

Code:

//Flag-controlled while loop.

//Number guessing game.

#include <iostream>

#include <cstdlib>

#include <ctime>

using namespace std;

int main()

{

int num; //variable to store the random number

int guess; //variable to store the number guessed by the user

bool isGuessed; //boolean variable to control the loop

srand(time(0));

num = rand() % 100;

isGuessed = false;

while (!isGuessed)

{

cout << "Enter an integer greater"

<<" than or equal to 0 and "

<<"less than 100: ";

cin >> guess;

cout << endl;

if (guess == num)

{

cout << "You guessed the correct "

<<"number."<< endl;

isGuessed = true;

}

elseif (guess < num)

cout << "Your guess is lower than the "

<<"number.\n Guess again!"

<< endl;

else

cout << "Your guess is higher than "

<<"the number.\n Guess again!"

<< endl;

} //end while

return0;

}
