Hi, I program in c# and i'm trying to learn c++. I can't seem to get a method to work right.

Here is what I have:

// more than one returning value

#include <iostream>

#include <time.h>

#include <string>


using namespace std;

 

int money = 1000;

string playername;

int currentmenu;

int choice;


void GetName ()

{ 

  cout << "What is your name?\n";

  getline(cin, playername);

}

void DisplayMainMenu ()

 { 


   cout << "1.Buy\n2.Sell\n3.Item Shop\n";

   cin >> choice;

   if (choice == 1)

   {

   DisplayBuyMenu();

   }

 }

void DisplayBuyMenu ()

{

  cout << "1. Item 1\n2. Item 2\n"; 

}

int main ()

{

 GetName();

 DisplayMainMenu();

 

  return 0;

}

The compiler tells me that DisplayBuyMenu() is not declared in this scope. Does anyone know what I am doing wrong? thanks.

You need to move DisplayBuyMenu above DisplayMainMenu.

Because you're calling DisplayBuyMenu before actually defining it, the compiler doesn't know about it and throws an error. You can put entire function above DisplayMainMenu, or just the header, so the compiler will know about it.
