Homework 3: Pick a number

I have to say that this task is a little more complicated than the previous exercises, because it was necessary to use a special function to generate numbers randomly. This program was thought as a game, where the user have to guess a random number. I decided to give the user only five chances to achieve it.

This is my code:

#include <iostream>
#include <stdlib.h>
#include <time.h>
using namespace std;

int main()
{
  int X, c=1;

  srand(time(NULL)); // random numbers are activated
  int N = rand()%100+1; // random numbers between 1-100 formula: rand()%(RANGE+1)+MINIMUM

  cout << "Let's play a game! \nYou have to guess the number I have in mind, but you only have 5 chances \nI'll give you a clue: the number is between 1 and 100" << endl;
  cout << "What number am I thinking? ";
  cin >> X;

  while (X!=N && c<5)
  {
    if (X>N)
    {
      cout << "Sorry but " << X << " is too high. \nYou have " << 5-c << " attempts remaining.\nTry again: ";
      cin >> X;
    }
    else if (X<N)
    {
      cout << "Sorry but " << X << " is too low. \nYou have " << 5-c << " attempts remaining.\nTry again: ";
      cin >> X;
    }
    c++;
  }

  if (X==N)
  {
    cout << "Congratulations winner! You have guessed my secret number" << endl;
  }
  else
  {
    cout << "You lost! \nThe number I was thinking about is " << N << " \nGood luck for the next time."<<endl;
  }
  return 0;
}

As you can see, I included a library call stdlib.h and time.h (that are necessary for generating random numbers).

I used conditionals to evaluate if the user entered the right value or have to try again, and a loop (a “while” specifically) with the purpose of repeating the procedure only five times if the user doesn’t guess the number.
