Okay.. I am learning about stuctures in C++ so I decided to write a small piece of code that might belong in an RPG. To do this, I wrote a structure to define what the separate armor pieces are, and another structure to define the attributes of each piece of armor. So.. I decided to have the members of the first structure to be of the type that the attributes are, (if that makes sense), and I have a few questions pertaining to my code. Here it is:
#pragma hdrstop
#include <condefs.h>
#include <iostream.h>
#include <math.h>
#include <conio.h>
#include <cstdlib.h>
#pragma argsused
struct armor_attributes
{
int price;
int durability;
int weight;
int protection;
};
struct armor //All the different types of armor (for the player
{ //and AI too!
armor_attributes helmet;
armor_attributes neck_guard;
armor_attributes r_shoulder_pad; //need to figure out a way for each piece
armor_attributes l_shoulder_pad; //of armor to have attributes, such as
armor_attributes r_glove; //durability, cost, protection factor,
armor_attributes l_glove; //weight, etc. Structure within a
armor_attributes breast_piece; //structure, perhaps?
armor_attributes abdominal_piece;
armor_attributes belt;
armor_attributes r_thigh_guard;
armor_attributes l_thigh_guard;
armor_attributes r_shin_plate;
armor_attributes l_shin_plate;
armor_attributes r_boot;
armor_attributes l_boot;
};
void init_player_armor() { //set armor ratings to begin the game with.
armor player; //instance of struct armor
player.helmet.price=10;
player.helmet.durability=50;
player.helmet.weight=5;
player.helmet.protection=2;
}
void display_armor() { //must be an easier way here too..
armor player;
cout << "Helmet rating: " << player.helmet.protection << endl;
cout << "Neck guard rating: " << player.neck_guard.protection << endl;
getch();
}
void display_main_menu() //the main main menu
{
clrscr();
cout << "Adventure Land!" << endl;
cout << "[N]ew" << endl;
cout << " ";
}
void do_stuff()
{
display_main_menu();
init_player_armor();
display_armor();
}
void main()
{
do_stuff();
}
Here are my questions:
1. I haven''t yet learned so much about scope, so here goes: I understand that variables declared in a statement block have scope in that block and blocks within that block. My question about scop is this: As you can see in my program, pretty much the way it is is that I have one block after another, and none of them are nested. So I was thinking that perhaps if that''s the case, variables declared in statement blocks above other statement blocks have scope within the others? Am I right in assuming this?
2. My other question is this: considering all the data members in my structures are the same type, is there a fast way to initialize all the data members? I tried doing this, but my compiler told me that it couldn''t convert type ''int'' to type ''armor''.
3. I completely stumbled onto the syntax shown above in which I referenced to player.helmet.price, etc. and I was wondering if this is good practice or not.. I can''t find anything about it in any of my texts.. I was also wondering if there''s any sort of limit to the number of structs within structs.
4. If I''m doing anything poorly, or there''s a way to make this easier and quicker, PLEASE LET ME KNOW!
Sorry I''m such a newbie.
Thanks a ton!,
