C++ :: Text Based RPG - Object Not Being Created?

Oct 24, 2013

I'm currently creating a text-based RPG, to get myself back into learning C++ again. The problem seems to be with the if-else ladder of statements, the user selects which race they wish to play as, which as a result creates the appropriate object for that race.

This is the character selection option code:

std::cout << "Please select a race: Human [1], Elf [2], Dwarf [3] or Orc [4]
";
std::cout << "Race selection: ";
std::cin >> race_selection;
std::cin.ignore();
switch (race_selection) {

[Code] .....

The problem here is, regardless of which race I use using the above switch statement, the Human object always seems to be created, instead of the object for the desired race.

C/C++ :: Make Class That Can Only Have One Object Of It Created?

Oct 7, 2014

make a class that you can make only one Object of it.

For example if you have Class A.
Let's say you create one object A* a=new A();

Now the next time you, try to create another object. For example:

A* b=new A(); What will happen is that b will get the same object (or reference) as a. In other words hey'll be pointing towards the same place. So basically you'll only have one object of it created. I tried doing it but I couldn't quite make it.

Here is what I tried: (but couldn't complete the exercise)

class God
{
public:
static int num;
static God* god;

C/C++ :: Get Reference To Text Object With The Name Of Object?

Aug 23, 2013

In Visual Studio 2010 C++
I have a series of existing text objects
The text properties names are
item1_lbl,
item2_lbl,
item3_lbl,
….

Based on a selection I want to change an object. I generate the name of the object I want to change in a string so from this string is there a way to get a pointer to the correct text object that is same name?

C++ :: Loop In A Text-Based RPG

Feb 13, 2013

I am working on my first RPG. Nothing fancy so far... I haven't developed a story or anything, just trying to get the gameplay hammered out. Anyway, I have a couple of NPCs and Items and I was wondering how I should program these interactive spots. I'm unsure whether I should loop the Room info or continue forward with if statements. With Items, I want to prevent the player trying to use the option to get the item again (after you pick up the item, the option is gone. Here are a couple examples of where I have the problem

else if(playerloc == 3)
{
cout << "There is a hooded figure in the corner. "
<< "The person waves you over.
";

[Code]....

What I want to do after the character interaction is complete is continue forward with the option to go south or east. I could return to the room menu, or continue by coding forward and allow the option to go east or south with more if-else-if chains..

In the next bit, I want to program the item to be picked up and then the treasure chest will be empty.

else if(playerloc == 5)
{
cout << "There is a treasure chest in the Northwest corner of this room.
"

C++ :: Pointer-based Data Loading From A (text) File

Dec 4, 2013

I have two classes, productListType and buyerListType, that are each basically linked lists. To create the linked list for an object of productListType, I successfully wrote a non-class function createProductList to read the product data from a text file. The class definition for buyerListType has a data member productBoughtRecord that is of type productListType to aggregate the details of the products purchased by a particular buyer during transactions. I decided to make productBoughtRecord a pointer since the contents of this data member would wax and wane over the course of several transactions, depending on the amount and frequency of payments made by the buyer. I have provided a rough sketch of the class below:

class buyerListType
{
public:
setCustomerInfo( ....., productListType* p);
.
.
.
private:
productListType* productBoughtRecord;
.
.
};

I'm similarly trying to write a non-class function createBuyerList to load the record of customers from a text file. How do I determine what the value of the formal parameter p in member function setCustomerInfo is, in order to be able to set the data member productBoughtRecord? take into consideration that an object of class buyerListType would have multiple buyers with varying amounts of products purchased.

C/C++ :: Text Based Game - Adding Players Names?

Mar 28, 2015

I am trying to make a very simple text based game and I want the players to be able to name their characters. Thus, I am trying to have the game ask "how many players will be playing:" and then taking that number (X) and create a place to store that information. I'm trying to get the game to ask, "What is the name of Player1?" Then once the user enters the name it would ask "What is the name of Player2" and that cycle would continue until PlayerX has entered their name. Is what I am doing close?

Here are the errors:

error C2143: syntax error : missing ';' before 'string'(ln 29 col 1)
Error2error C2678: binary '<<' : no operator found which takes a left-hand operand of type 'std::basic_istream<char,std::char_traits<char>>' (or there is no acceptable conversion) (ln 30 col 1)

int NumberOfPlayers;
if (Response1 == "Yes") {
cout << "
How many players will be joining us on our adventure: ";

C++ :: Write Interactive Text Based Menu Interface (using A Loop)

Sep 27, 2013

Write an interactive text based menu interface (using a loop) that will allow the user to

Enter a task or assignment Display all of the tasks that are in the file Find a task by Course Quit For each task, you need to keep track of:

Course Name that it is for (e.g., CS162)
Description of the assignment (e.g., Finish Lab 2)
Due date (e.g., 9/26/2009)

Allow the program to keep looping until user wants to quit. When the program starts, it should load the tasks from external file ("tasks.txt") into memory. When user enters the three items of a task, the program needs to read them in, save them in memory and eventually write them to the external data file ("tasks.txt"). The file format could look like: (The ';' is used as a delimiter or field seperator.)

Some Implementation Requirements:

Write at least four functions WITH arguments for this assignment. Use struct named Task to model task Use array of structs to model the collection of tasks. Hint: In this assignment, the description and course name may have multiple words in it. Therefore, you now SHOULD read using the 3 argument version of get. Watch out. When using the 3 argument version of get you need to make sure to remove the delimiter or newline. Therefore, anytime you read (even a confirmation message), make sure to eat the newline! Make sure to have a delimiter written between each item in the file – like a newline. This will be important when you read the information back from the file.

This is my code so far:

#include <iostream>
int main()
{
char cname[25],desc[20];

[Code]....

C++ :: Generate A Report Based On Input Received From A Text File

Nov 5, 2014

Here is the assignment... Write a program to generate a report based on input received from a text file. Suppose the input text file student_status.txt contains the student’s name (lastName, firstName middleName), id, number of credits earned as follows :

Doe, John K.
3460 25
Andrews, Susan S.
3987 72
Monroe, Marylin
2298 87
Gaston, Arthur C.
2894 110

Generate the output in the following format :

John K. Doe 3460 25 Freshman
Susan S. Andrews 3987 40 Sophomore
Marylin Monroe 2298 87 Junior
Arthur C. Gaston 2894 110 Senior

The program must be written to use the enum class_level :

enum class_level {FRESHMAN, SOPHOMORE, JUNIOR, SENIOR } ;

and define two namespace globalTypes (tys and fys) for the function :

class_level deriveClassLevel(int num_of_credits) ;

The function deriveClassLevel should derive the class_level of the student based on the number of credits earned.

The first namespace globalType tys should derive the class level based on a two year school policy. And the second namespace globalType fys should derive the class level based on a four year school policy.

Four Year School Policy:
Freshman 0-29 creditsSophomore 30-59 credits
Junior 60-89 creditsSenior 90 or more credits

Two Year School Policy:
Freshman 0-29 creditsSophomore 30 or more credits

and this is the code I have so far...

#include <cstdlib>
#include <iostream>
#include <cctype>
#include <fstream>
using namespace std;
enum class_level {FRESHMAN, SOPHOMORE,JUNIOR,SENIOR};
class_level classLevel;

[Code] .....

My main question is did I use the namespaces and enum correctly? And my second question is whats the best way to input the data from the text file? This is really where I get stuck.

Marylin Monroe 2298 87 Junior

The program must be written to use the enum class_level :

The first namespace globalType tys should derive the class level based on a two year school policy.
The second namespace globalType fys should derive the class level based on a four year school policy.

So I basically did it in parts and got everything working and then had to make the namespace so I had this:

#include <iostream>
#include <fstream>
#include <string>
using namespace std;
enum class_level { FRESHMAN, SOPHOMORE, JUNIOR, SENIOR };

[Code] ......

I know I have to clean it up and change it but it ran like it was suppose to. Then I tried adding the global namespaces and I this:

#include <iostream>
#include <fstream>
#include <string>
using namespace std;
enum class_level { FRESHMAN, SOPHOMORE, JUNIOR, SENIOR };
class_level classLevel;

[Code] ....

with this i keep getting an error saying tys::deriveClassLevel: must return a value and tys::fys::deriveClassLevel: must return a value. I have been messing around with this part and struggling I thought I used the namespace to run the if statements with the criteria for the years of school. Basically I have been stuck for awhile and trying to change things around but I cant seem to get it to work.

C++ :: Generate Report Based On Input Received From Text File - User Defined Namespace

Nov 11, 2014

Write a program to generate a report based on input received from a text file. Suppose the input text file student_status.txt contains the student’s name (lastName, firstName middleName), id, number of credits earned as follows :

3987 72
Monroe, Marylin
2298 87
Gaston, Arthur C.
2894 110

Generate the output in the following format :

John K. Doe 3460 25 Freshman
Susan S. Andrews 3987 40 Sophomore
Marylin Monroe 2298 87 Junior
Arthur C. Gaston 2894 110 Senior

The program must be written to use the enum class_level :

and the second namespace globalType fys should derive the class level based on a four year school policy.

Four Year School Policy:
Freshman 0-29 creditsSophomore 30-59 credits
Junior 60-89 creditsSenior 90 or more credits

Two Year School Policy:
Freshman 0-29 creditsSophomore 30 or more credits

NOTE : use ignore() function with ifstream objects whenever you want to ignore the newline character.

For example :
ifstream transferSchoolFile ;
transferSchoolFile.open("student_status.txt", ios::in);

while( !transferSchoolFile.eof()) {
getline(transferSchoolFile,name) ;
transferSchoolFile >> id >> credits;
transferSchoolFile.ignore(); //Used here to ignore the newline character.
….
}

I did this in parts so I got it working with a four year criteria without the user defined name spaces.

include <iostream>
#include <fstream>
#include <string>

using namespace std;
enum class_level { FRESHMAN, SOPHOMORE, JUNIOR, SENIOR };

[Code] ....

So that worked fine then I tried with name spaces -

#include <iostream>
#include <fstream>
#include <string>
using namespace std;
enum class_level { FRESHMAN, SOPHOMORE, JUNIOR, SENIOR };
class_level classLevel;

[Code] ....

I know I have some stuff to mess around with but I am currently stuck with two errors, first -

Error1error LNK2019: unresolved external symbol _main referenced in function ___tmainCRTStartupC:UsersstephenDocumentsVisual Studio 2013ProjectsinputConsoleApplication1MSVCRTD.lib(crtexe.obj)ConsoleApplication1

C++ :: String Stream Object And Text File Data Access

Jan 21, 2014

I have two puzzling issues I am dealing with.

Issue 1: I am using a stringstream object in a block of my program that needs to be visited repeatedly depending on a user's selection from a menu. I want the contents of this stringstream object to be cleared any time control gets to this part of the program. I have tried the clear and flush functions to no avail.

Issue 2: I am reading data from a source text file that would be regularly changed during the course of program run. After the program run is over, I am supposed to save the results(which is basically the source text file AND all updates) in a destination file. This destination file would then serve as the source file when next the program is run. In other words, I want a scenario where my results overwrite the original contents of the source file; implying that my source and destination files are now one, pretty much. How can I do this?

C++ :: Processing Buttons Created At Runtime

Oct 7, 2014

I am developing a small game using MFC in which the game options like new game, save, open, exit etc. can be selected from the menu as well as from the buttons inside the window. I have no problems with the menu but the buttons do not seem to work at all.

The buttons are created at runtime using CButton class. To associate the buttons with the corresponding functions, I just used the same resource ID for the buttons as the menu options, but that did not work. When I click on the buttons, nothing happens. If I assign different resource IDs to the buttons, how do I handle the message map entries? Do I have to write different message map entries for the menus and the buttons while their function is exactly the same?

C++ :: Arrays Are Actually Created With A Size Indication?

Jan 14, 2014

Reading Effective C++ by Scott Meyers, and Item 16 claims that when an array is created, the compiler reserves a block of memory at the very beginning to indicate how many objects are in the array.

n = number of objects
|n|index0|index1|...etc

Scott Meyers wrote:This is just an example, of course. Compilers aren't required to implement things this way, though many do.

Supposedly, this how delete knows how many objects to destruct. And if you were to do something like:

int* foo = new int;
//Stuff
delete[] foo;

Then delete would interpret the first block as the number of items to destruct, then continue on and destruct that many blocks of memory onward, causing UD behavior.

Is there any truth to this?
