The computer chooses a random number using the following random generator function srand(time(NULL)); int r = rand() % 100 + 1; that creates a random number between 1 and 100 and puts it in the variable r. (Note that you have to include <time.h>) Then it asks the user to make a guess. Each time the user makes a guess, the program tells the user if the entered number is larger or smaller than its number. The user then keeps guessing till he/she finds the number. If the user doesn’t find the number after 10 guesses, a proper game over message will be shown and the actual guess is revealed. If the user makes a correct guess in its allowed 10 guesses, then a proper message will be shown and the number of guesses the user made to get the correct answer is also printed. After each correct guess or game over, the user decides to play again or quit and based on the user choice, the computer will make…arrow_forwardint main() int i = 3, * j, k; j = &i; k = i; "j= 10; cout << i * *j * i + *j*k; return 0; O 30 3 O 20 20 O 10 20 O 10 30arrow_forward#include<iostream>using namespace std;void main(){double pi = 0, denominator = 1;int counter = 999999;for (int x = 0; x < counter; x++){if (x % 2 != 0){pi = pi - (1 / denominator);}else{pi = pi + (1 / denominator);}denominator = denominator + 2;}pi = pi * 4;cout << " So the computed value of a PI is = " << pi << endl;cout << " ";//return 0;system("pause");} Note: This a program called ComputePI to compute the value of π Tutor just have to Modify This program to use nested-if (if ... else if ... else if ... else) instead.
