Question

Write a c++ program to pull a random number between 1-100 inclusive. Ask the user to guess the number. If the random number is higher than the guess, print "Higher". If the random number is less than the guess, print "Lower". If the random number is equal to the quess, print "Correct!".

Create a variable to count the number of guesses and intitialize it to zero.
int guesses=0;
Increase this variable by 1 every time the user enters a new guess. Print the number of guesses at the end.

eg:
I pulled a random number 1-100. Enter your guess:
50
Lower
20
Higher
25
Correct! You guessed my number in 3 tries.

Answer 1

Below is your answer:

#include <iostream>
#include <cstdlib>
using namespace std;

int main() {
  //seeding to generate random number correct always
  srand( time(NULL) );
  //generate random number, formula is as below
  //(rand() % (higher - lower + 1) + 1)
  int random = (rand() % (100 - 1 + 1)) + 1; 
  //intitialize gues count
  int guesses=0;
  //initial prompt
  cout<<"I pulled a random number 1-100. Enter your guess: "<<endl;
  int num;
  //loop to get the number from console
  do {
    cin>>num;
    //increment guess
    guesses++;
    //check if lower or higher
    if(num < random) {
      cout<<"Lower"<<endl;
    } else if(num > random){
      cout<<"Higher"<<endl;
    }
  } while(num != random);//finish loop when number is guessed
  //printing the result
  cout<<"Correct! You guessed my number in "<<guesses<<" tries."<<endl;
  return 0;

}

Output
