How to assign questions in loop?

[MisterTams]

Hey guys I'm trying to get back into C++. I'm just experimenting with a program I created. I'm trying to get the user to answer a few questions in an assigned quiz. I'm having trouble using the loop to label each question with a number (1,2,3,4,5) and at the same time have a different question assigned to each. For question #1 I would like to have it ask "how old are you?"
For question #2: Do you own property? For question #3: Do you operate a motor vehicle? You get the idea, just messing around and experimenting with totally bogus made up questions. Also in the earlier part of my code I would like to end the program after the user enters "no". How could I do that as well? Thanks!

  //Practice


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

int main ()	
{
	int x, i;
	string response;

	cout << "Please enter a number (1 or 2)" << endl;
	cin >> x;
	
	while ( x > 2)
	{ 
		cout << "Error!" << endl;
		cout << "Please enter (1 or 2)" << endl;
		cin >> x;
	}
	
	if (x == 1)
		cout << "Congrats! You have been entered for a chance to win $100!" << endl;
	else if (x == 2)
		cout << "Congrats! You have been entered for a chance to win an Ipod!" << endl;
	
	cout << "Are you ready to take a short quiz for a chance to win?" << endl;
	cout << "Please answer (yes or no)" << endl;
	cin >> response;
	cout << "You answered " << response << endl;
 
	if (response == "yes")
		cout << "Thanks for taking part in the quiz!" << endl;
	else if (response == "no")
		cout << "No problem, now exiting." << endl;
		
	for (i=1; i<6; i++)
		{cout << "Question" << i << ":" << "how old are you?" << endl;
	}
	system("pause");
	return 0; 
}

If I was to do it, I would write all my questions into a different string (globally) and then write a quick function for the numbering at the beginning of the line, and write a separate function to display each question. Using a compare statement for i in the previous function, it would display a certain question.

So like :

  int i = 0

  int counter(){
    Int begin = 0;
    while(begin <= 5){
  cout >> i ": " << question();
i++;
         
}

To get you started.

Do you think you could show a general example of this? I tinkered around but the function didn't want to work when I placed it inside cout. I made a function called void questions(); and placed the questions inside of that function.

I tried something like
cout << "Question " << i << ":" << question();

Why not create a simple menu utility? Code you could reuse and change as needed:

MenuUtility.hpp

// MenuUtility.hpp

#include <iostream>
#include <string>

namespace menuNamespace
{
   int menu(std::string* strArray, int size);
}

MenuUtility.cpp

// MenuUtility.cpp

#include <iostream>
#include <string>

namespace menuNamespace
{
   int menu(std::string* strArray, int size)
   {
      int userResponse = 0;

      std::cout << "Your choices are:" << std::endl;

      while (userResponse < 1 || userResponse > size)
      {
         for (int i = 0; i < size; i++)
         {
            std::cout << i + 1 << ") " << strArray[i] << std::endl;
         }
         std::cin >> userResponse;
      }
      return userResponse;
   }
}

Test.cpp

#include "MenuUtility.hpp"

int main()
{
   std::string example[] = { "attack","retreat" };

   int choice = menuNamespace::menu(example, 2);

   std::cout << "\nYou chose menu item #" << choice << ", " << example[choice - 1] << "\n";
}

I'm sure the menu utility could be improved using vectors instead of arrays, but it works as is.

I had seen a menu written in C and made a quick attempt to rewrite in C++. This is a years old code slam.

One reason to rewrite the menu utility using a vector is you could randomize the order using an STL algorithm, like std::random_shuffle.
http://www.cplusplus.com/reference/algorithm/random_shuffle/

There is lots of room to improve that code in many ways. ;)
