Question type program for beginners

I made this program for someone who asked me for a little help with C++, it is for begginers and shows how you could make a basic Question type program.

Code:

---


#include <iostream> // For cout, cin etc..
#include <conio.h>

int Question; // We store the answer to the question here

int main()  //Required in almost every program
{
    cout << "What is the answer to 4 + 8?\n\n";  // We ask the user a question
   
    cout << "1) 13\n2) 12\n3) 14\n\n"; //The possible answers *note* \n is for a newline
 
    cin >> Question;        //The user needs to put an input here which will be stored
                            //in out int variable "QUESTION"
     
if(Question  == 2)          //If the user entered the correct answer which is 12
{                          //the program will do this piece of code
    cout << "\nYou answered correct\n";
    cout << "\nPress any key to continue...\n\n";
    getch();
}

else                        //If it was not what the if statment asked for do this
{
    cout << "\nYou answered incorrectly\n";
    cout << "\nPress any key to continue...\n\n";
    getch();
}

cout << "Have a nice day\n";


return 0;                      //Exit the program

}                  //End Int Main()

//Incase your not familar with using "if" and "else". if statments will preform
//a piece of code if the code in the brackets "()" if true, below is an example
//of an alternative way the if statments could of been used you can check for
//more than one scenario just by adding "else if" below the if section:
//  if(Question == 1)
//  {
//  [Code goes here]
//  }
//
//  else if(Question== 2)
//  {
//  [Code goes here]        // In this program this would be the correct option
//  }
//
//  else if(Question == 3)
//  {
//  [Code goes here]
//  }
//
//  else
//  {
//  [Code goes here]
//  }

//It is always wise to include an else statment just incase the user enters something
//different to what you wanted them to enter, for example if they entered a char type
//instead of an int the program would not know what to do and something would
//go wrong

Code:

---

system("pause");

dont use system :p its almost as bad as goto

Do you have an alternative?

I don't like my programs quitting before they start, with my comp I can't even see the text before it terminates.

LoL =)

To compliment the if statement structure (or rather, suggest an alternative), here's the switch method:

Code:

---

    switch (QUESTION)
    {
        case 1:
            cout <<"Close, but not quite\n";
            break;
        case 2:
            cout <<"Correct\n";
            break;
        case 3:
            cout <<"Hmmm, not bad, try again.\n";
            break;
        default:
            cout <<"Nah... you're loosing it now!\n";
            break;
    }

---

Isn't the FAQ a little weak at the pause section?
Both examples requires conio.h, which isn't standard.

There are better ways to pause a program.

Code:

---

int QUESTION; // We store the answer to the question here

---

I'd recommend to use full CAPS for macros only eg.

Code:

---

#define QUESTION 1
