Void list? C++

BattleCrazy99 (18)
I am not asking anybody to help write the code but for the project i am trying to do i have a simple animal menu, where the user enters in a number and it displays what the animla would say, but my the problem i am stuck on is right at where the animal says part. cause my teacher is using Void Feature for each. My question is that do i have to number or declare each to a number certsin set of number to let it then display. if so how do i go from doing this.

#include "pch.h"
#include <iostream>
#include <iomanip>
#include <stdio.h>
#include <math.h>
#include <string>
using namespace std;
float useranswer;
#define TRUE 1
#define FALSE 0
#define MENU_UNSET -1 // no menu option selected
#define MENU_LOWEST 1 // indicates the value of the lowest menu code
#define MENU_DOG 1 // DOG option...
#define MENU_CAT 2 // CAT option...
#define MENU_BIRD 3 // BIRD option...
#define MENU_MOUSE 4 // MOUSE option...
#define MENU_COW 5 // COW option...
#define MENU_FROG 6 // FROG option...
#define MENU_ELEPHANT 7 // ELEPHANT option...
#define MENU_DUCK 8 // DUCK option...
#define MENU_FISH 9 // FISH option...
#define MENU_SEAL 10 // SEAL option...
#define MENU_FOX 11 // FOX option!!!
#define MENU_EXIT 12 // indicates the user wants to exit
#define MENU_HIGHEST 12 // indicates the value of the highest menu code
// Provide function prototypes.

This is an oddly-structured homework. It kind looks like your teacher is planning to use this as an example to segue into OOP.

In any case, notice that you have your animal menu code twice. This is a good hint that you should put it in a function, then call that function.

You should also get your code to compile, at the very minimum, before posting questions.

Then, put your code in [code]…[/code] blocks.

The useranswer should not be a global, and it should be an integer.

This is not correct.

  if (cin.fail() == false) 
  {
    cin.clear();
    rewind(stdin);

Your loop should look like this:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
 
  int useranswer;

  bool done = false;
  while (!done)
  {
    show_menu();
    cin >> useranswer;

    if (!cin || (cin < 1) || (cin > 12))
    {
      cin.clear();
      cin.ignore( numeric_limits <streamsize> ::max(), '\n' );
      cout << "complain...\n";
    }

Now, once you have your input, you need to act on it.

1
2
3
4
5
6
7
8
 
    switch (useranswer)
    {
      case 1: Feature_DOG(); break;
      case 2: Feature_CAT(); break;
      …
      case 12: done = true; break;
    }
  }

Unless your instructor specifically asked for it, you do not need to #define TRUE, FALSE, MENU_anything, or whatever.


If you wish your menu to be an enumerated construct, you can do that; just make the menu function return a valid enum value:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22
23
24
25
26
27
28
 
enum Menu_Item
{
  Menu_Dog = 1,
  Menu_Cat,
  …,
  Menu_Exit,
  Menu_Last = Menu_Exit
};

Menu_Item menu()
{
  …
  cout << "1. ) What does the dog say?\n";
  …

  int userinput;
  while (true)
  {
    cin >> userinput;
    if (!cin || (userinput < 1) || (userinput > Menu_Last))
    {
      cin.clear();
      cin.ignore( numeric_limits <streamsize> ::max(), '\n' );
      cout << "complain...\n";
    }
    else return (Menu_Item)userinput;
  }
}

There are much better ways to do this, but at this point I think they would be overload for you.

Hope this helps.

Here's how I would shorten it up. One function call is all that's needed.

...which is nice, but does not satisfy the homework instructions given to BattleCrazy99.
