อยากถามคนที่เคยเรียน program c++ หรือผู้รู้ก็ได้ค่ะ
ว่าข้างล่างนี่มันแปลว่าอะไร ทีล่ะบรรทัดนะค่ะ

#include <iostream>
#include <ctime>
#include <cstdlib>

#define MAX_GUESS 7
#define MAX_RANGE 1000

using namespace std;

bool inRange(int g);
void playGame();

int main()
{
    char answer;
    cout << "Welcome to the game GuessNumber" << endl;
    cout << "You must guest a number between 1 and "
         << MAX_RANGE << "\n"
         << "You can win if you can guess the number within "
         << MAX_GUESS << " times." << endl;

   do
   {   playGame();

cout << "\n Do you want to play again?[y/n]:";
   cin >> answer;
   } while (answer == 'y');

   return 0;
}

bool inRange(int g)
{
    if (g>=1 && g<=MAX_RANGE) return true;
    return false;
}
void playGame()
{
    srand(time(NULL));
    int x = rand()%MAX_RANGE + 1;
    int g;
    // to store all guess numbers
    int guesses [10]= {};
    for (int i=1; i<=MAX_GUESS; i++)
        {
        cout << "Guess " << i << " : ";
        cin >> g;
      // Storing a guess number
        guesses= g;

        if (inRange(g)) {
            if (g==x) {
                cout << "*** Hurrah! You are correct" << endl;
                return ;
            }
            else if (g<x) {
                cout << "It's too little" << endl;
            }
            else {
                cout << "It's too much" << endl;
            }
        } else {
            cout << g << " is not in the valid range of 1-"
                 << MAX_RANGE << endl;
        }
        //Showing all previous numbers
        cout << "Previous guesses are";
        for (int j=1; j<=i; j++)
        {  cout << guesses[j] << " ";
        }
        cout << endl;
    }
    cout << "*** Sorry! you lose!" << endl;
    cout << "... The number is " << x << endl;
    return ;
}
