C++ :: Creating Inventory - Array With More Than 1 String?
Jul 14, 2014How would i do this? Im trying to create an inventory but this just will not work, when i do it how i have it originally (as shown below):
cout << "Do you have weapons and armor?: ";
cin >> yEquip;
if (yEquip == 'y') {
cout << endl;
string invintory2[6] =
[Code] ....
the program outputs this:
cout << "Do you have weapons and armor?: ";
cin >> yEquip;
if (yEquip == 'y'){
cout << endl;
string invintory1[6];
[Code] ....
however programing it like this seems very... time consuming.
my other arrays (normal ones that just hold a set of int's) look like this:
int *player[] = {&yhp,&ymp,&ypatk,&ymatk,&yratk,&ypdef,&ymdef,&yrdef,&ydb,&yacc,&ycr,&yas};
Is there any way to do a string array in this way?
C++ :: Inventory Control Application - Editing Text File
Nov 14, 2014You are requested to create an inventory control application for a drink stall (give a name to the stall). The application is used to show the list of drinks the stall sells, how many of each item on‐hand and the cost of each item. The records are to be saved and retrieved to/from a binary file called “drinks.txt”. For each drink in the stall, your program is to keep the information as a Record Structure called DrinkRecord. The structure should at least consist of the following:
(1) Item Number
(2) Item Name
(3) Quantity
(4) Unit Price
Your application should have the following features:
(a) Display a drink information
(b) Add a new drink information
(c) Update a new drink information
(d) Delete a drink information
(e) Display all drink information
#include <string>
#include <fstream>
#include <vector>
#include <iterator>
#include <algorithm>
#include <stdlib.h>
#include <iomanip>
[code].....
Everything works fine with minor issues, but I'm having trouble with the editing function. I need to be able to search for a specific drink then be able to edit its contents and print the new contents to the file. I have not created a structure yet. I will do that as soon as possible.
C++ :: What STL Container Should Be Used For Inventory
Mar 27, 2014So I'm writing an RPG and I'm in need of an inventory system. Of course as an relatively old member of the forum I know best than just come here and ask so I've already researched quite a bit and I've formulated this idea.
I've kind of conceptualized it like so: I'll have some sort of STL container of a unique_ptr of my base item class. There will be derived item classes. Taking advantage of polymorphism I can then call the new Derivedclass when inserting it in the STL container.
My questions are: What STL container should be used for the inventory(fixed sized)?
C :: How To Input Inventory For Character
Jan 15, 2015im working on mine first 2d game and im practicing a lot, how to input my inventory for character ( for items, and others ) So, i just want to let u know that i have :
#define WEAPON_LONGSWORD (1)
#define WEAPON_WARAXE (2)
#define WEAPON_DAGGER (3)
#define WEAPON_SHORTSWORD (4)
#define WEAPON_BOW (5)
#define WEAPON_MAX (6)
So, i want to put this in my shop and if i buy it i want to appear in my inventory, or sell sell trought my inventory.Also i have one define
#define WEAPONBEGIN_WOODENSTICK (1)
Which will go instant ( when u create character ) to inventory. And:If i have 1, 2, 3, 4, 5, 6, 7, 8, 9 slots ( example ) and i sell item which was on 3rd slot, what will happen with others ? will they just go back for one slot or ?

C++ :: How To Get The Cross Product
Oct 10, 2014I am trying to compute the cross product of an 1x6 column vector "D" with a 6xN matrix "S".
vector< vector<float> > D(1, vector<float>(6));
vector< vector<float> > S(6, vector<float>(10)); // Example where N = 10
float cProduct = D*S; // ?
The last line fails, so I'm wondering how you would get the cross product?
C++ :: For Loop To Sum Up Product Of Several Arrays
Feb 2, 2013I need a for loop that sums up the product of several arrays.
int total = 0;
for (int i=0; index < (columns - 2); index++)
for(int indexFF = 0; indexFF < CG[index + 2] - 1; index++)
for (int indexIN = 0; indexIN < CG[index + 1] - 1; indexIN++, total++)
NRN[CG[index + 1]+indexFF] += FF[total] * NRN[indexIN + CG[index]];
right now "columns" is set to 3
CG[] is an array of 10 integers for "column groups"
for now they are set to:
CG[0] = 0
CG[1] = 3
CG[2] = 4
CG[3] = 3
NRN[] is an array of floating points
NRN uses CG to map its indexes out
0 3 7
1 4 8
2 5 9
_6
FF[] is an array of random numbers basically constants
I need the for loops to sum:
NRN[0] = 0.5
NRN[1] = 0.75
NRN[2] = -1
NRN[3] = NRN[0]*FF[0] + NRN[1]*FF[1] + NRN[2]*FF[2]
NRN[4] = NRN[0]*FF[3] + NRN[1]*FF[4] + NRN[2]*FF[5]
NRN[5] = NRN[0]*FF[6] + NRN[1]*FF[7] + NRN[2]*FF[8]
NRN[6] = -1
NRN[7] = NRN[3]*FF[9] + NRN[4]*FF[10] + NRN[5]*FF[11] + NRN[6]*FF[12]
NRN[8] = NRN[3]*FF[13] + NRN[4]*FF[14] + NRN[5]*FF[16] + NRN[6]*FF[17]
NRN[9] = -1
NRN, FF and CG are the only things in other code that I can't change in the loops
when I debug it index goes to 3 and overflows its memory. which it shouldn't because columns = 3 so "index < (columns - 2)" should stop at 1
C++ :: Create Inventory System Using Classes And Objects?
Jan 13, 2015I'm trying to create an inventory system in C++ using classes and objects. Here is what I have now
Item.h
#pragma once
#include <iostream>
#include <allegro5/allegro.h>
#include <allegro5/allegro_image.h>
[Code]....
Basically what I want my inventory system to become is this: [URL] Each slot can hold an item.
Basically this inventory system should be able to do what RS Inventory system can do. (Hold items, Use items, Equip Items (No need for moving item))
C++ :: Program That Prints A Discounted Product
Sep 29, 2014So I need to make a program that reads distance and number of days of a person that is buying a ticket. If distance is greater than 1,000 kilometers AND the person stays more than 7 days, the discount is 30% of the ticket. The cost per kilometer is $1300. Print the ticket with discount.
I used variable distance as float because it will be multiplied with 0.3 for the discount... not sure if I'm right on that.
Code:
#include <iostream>
#include <conio.h>
using namespace std;
int main() {
float distance;
int days;
[Code] .....
I tried another way but haven't done it in code...
ask for distance
ask for days
Ticket= (Dist x 2 x $1300)
If (dist>1000) && (days>7)
cout<<Ticket=Ticket * 0.3;
else { cout<<Ticket;
C++ :: Kronecker (direct) Vector Product
Feb 19, 2013How to code the Kronecker/direct product of two vectors??
The direct product of the vectors a and b is given as the matrix below (note "x" refers to x with a circle around it and is the symbol for a Kronecker product):
(a1, a2,..., an) "x" (b1, b2,...,bn) = [a1b1, a1b2,..., a1bn]
[a2b1, a2b2,..., a2bn]
[ . . . . ]
[ . . . . ]
[ . . . . ]
[anb1, anb2,..., anbn]
The way I have coded the rest of the program is such that the matrix shown here is represented by a vector of length equivalent to the number of elements in the matrix. So I want the Kronecker product to give me a vector of length n^2 (where n is the number of elements in each initial vector).
C :: Inventory Program - Entering Amounts With Two Decimal Places
Jun 7, 2013So my inventory program runs fine as far as I can tell. Except when entering "Amounts" with more that 1-precision . ie
Amount Entered : 25.99 // Problem
Amount Entered : 25.9 // No Problem
When entering say 25.99, the rest of the file is jibberish. but 25.9, the rest of the file is fine
Code:
#include <stdio.h>
typedef struct toolRecord{
int record_num;
char tool_name[16];
int quantity;
double price;

C# :: Update Initial Values Once User Has Added To Inventory
Apr 10, 2015I am having some trouble creating a listbox in visual studio. I declared an array, set initial values, and now I would like to be able to update those values. It is a pizza inventory app, so I need to update the initial values once the user has added inventory. This is the code I have for the "Update Inventory" button:
// read in value and convert to double
double dblInput = Convert.ToDouble(txtInput.Text);
// loop through ingredients and add inventory to selected ingredient
for (int i = 0; i < dblInventory.Length; i++) {
// is item at i checked for update?

C++ :: Calculate Product Of 4 Vertical Values In Matrix
Jun 1, 2013I am attempting to create a program which calculates the product of 4 vertical values in the matrix. The numbers are supposed to be randomly generated and the size of the matrix is given through the command window.
However I seem to have either not pointed my matrix through all of my functions correctly, or my logic is off somewhere as I keep getting this output regardless of the size of matrix I put in:
"the location of the highest horizontal line product is: 5 0 and is the number: 0
The overall max value is 4196352 at the above coordinates."

C++ :: Array Of Structures - Storing Product Information
Nov 5, 2013I have been dealing with this problem for quite some time, I've been assigned to develop a program that can store products' information within structures (the number of products is undefined). I thought I should use an array of structures, but I don't know how to declare it properly. This is what I thought would work:
struct product {
string name;
string in_stock;
float sale_cost;
int id; }
prod [n]; //n being the undefined number of products the user will register/delete/modify
I already saw an example of array of structures, but it uses a defined number.

Jun 20, 2013What I am trying to do is a small program that creates accounts (User name, age,...), and stores it on a CSV file. And later I can search for a user and edit some information about him (example, his age).
Here is my code:
#include <fstream>
#include <iostream>
#include <string>
#include <stdio.h>
#include <io.h>
#include <stdlib.h>
#include <string>
Looking at the "old code" ("void searchaccountold()"), I am sure the problem is on the "while" part ("while (myfile >> name >> age >> money)").
It should work, but it doesnt. I am almost sure the problem lies on the ";"... Because the CSV uses cells, and to pass to the second cell I would normaly need an ";" and in my case I have ">>". I have tryed to change them, to use getline, etc... and didnt work.
C++ :: Creating Variable Name For Binary File
Dec 11, 2013I'm attempting to split a large binary file into smaller manageable files for analysis. I've written most of the software but I'm stuck in a couple of places.
1. The binary file is split by looking at a couple of bytes to determine when to create a new file or continue appending to the current new file. The question is when I need to create a new file, how can I dynamically sign it a name? My intention is to rename each subfile by: "original_name" + new section id + ".log".
2. The start of each section is determined by a specific pattern (6 bytes of FF's). I'm running into an issue where the pattern check is checking for 5 bytes instead of 6 because the for..loop doesn't increment for one instance.
I've attached the code I have so far.
#include <iostream>
#include <stdlib.h>
#include <stdio.h>
#include <string>
#include <sstream>
