[QUOTE=invisal;653516][B]Text-based Role-Playing Game Project [COLOR="Green"](For Beginners)[/COLOR][/B] [INDENT]Firstly, this game will start with an introductatory storyline of the game to attract player interest. Then, it asks a player to enter his or her name and which class the player want to choose. There are going to be 3 classes for player: …

[QUOTE=twek;728917]title is self explanatory how do i convert it to a std::string? all this LP stuff makes my brain hurt...[/QUOTE] try static_cast<std::string>(the_LPWSTR_var); or if it doesn't work reinterpret_cast<std::string>(the_LPWSTR_var);

You can do it your self if you know some math :) w o r d = 4 letters which aren't the same = 4! s h e e p = 5! / 2! (the 2 ee)

Get a book. I started with [URL="http://www.amazon.com/Beginning-C-Game-Programming-Development/dp/1592002056"]Beginning C++ game programming[/URL]. It's a great book to begin with.

[QUOTE=serkansendur;730786]is there any vay to access iterator's index value without using another variable in the for loop?[/QUOTE] [code=C++] #include <iostream> #include <vector> using namespace std; int main() { vector <int> vec; vector<int>::iterator iter; for(int i = 0; i < 5; ++i) vec.push_back(i); for(iter = vec.begin(); iter < vec.end(); ++iter) cout …

You overload an operator when it makes sense to do so. Say that you create a custom string class [b]MyString[/b]. It makes sense to overload the [b]+[/b] operator, but not the ~.

shoe_copy=shoe1; will call the assignment operator, not the copy constructor. The copy constructor is called for example when you pass an object to a function by value. // copy constructor called (notice I pass by value, not by reference) void f(Shoe s) { }

You can do that: [code="C++"] bool checkUnsignedInt(const string &str) { return atoi(str.c_str()) >= 0; } [/code]

You can't return two values from a functio using the return statement. Use a struct as you've been told to above: [code="C"] typedef struct { int x, y; } P; P getPoint() { int a, b; //a = .... b = ..... P temp; temp.x = a; temp.y = b; …

Well my main() function has become a mess... What should I do next time to prevent this? [code="C++"] int main(int argc, char *args[]) { srand((unsigned)time(0)); if(!init()) return 1; atexit(cleanup); // to cleanup the surfaces // load images background = loadImage("background.jpg"); message = loadImage("play_again.jpg"); youWinMessage = loadImage("you_win.jpg"); youLoseMessage = loadImage("you_lose.jpg"); start: …

[QUOTE]What I am trying to do is change the cin >> varible; into something different so when I find it easier when I code.[/QUOTE] Why do this? Is [b]cin[/b] hard to remember? You need to get used it, you'll see it everywhere!! Think of it as "[b]c[/b]onsole [b]in[/b]put", this might …

Try darkGDK, it's free and very easy to use. Google it.

[code=C++] #ifndef DARK_OBJECT_H #define DARK_OBJECT_H #include "DarkGDK.h" namespace DarkObject { class Object // abstract { public: Object(); virtual void x() = 0; protected: int imageID, spriteID; }; class Rect2D { public: Rect2D(int x, int y, int width, int height): x(x), y(y), width(width), height(height) {}; int GetX() const {return x;} int …

[code=C]#include <stdlib.h> /* needed for rand() function */ #include <time.h> /*needed to call srand() (explained below)*/ int main(void) { int r = 0; /* by calling this function, we seed the random number generator.

[code=C++] void increment(const Machine &aMachine, int amount = 1) { rackID = rackID - amount; } [/code] [B]1.[/B] You are passing aMachine as [B]constant[/B] reference and you are trying to change a member of aMachine. This is illegal, since it's constant. You could pass a reference: Machine &aMachine [B]2.[/B] void …

[B]result[/B] is a local variable, which is destroyed when the functions ends. So a garbage value is destroyed. The best solution is to do what is said by the poster above. If you need to work with pointers you can do this: [code=C++] double* treble(double data) { double result = …

Hi, I'm studying operator overloading through [B]C++ the complete referece[/B] and I've got some questions. In the book, the author writes this: [code=C++] loc loc::operator++() { ++longitude; ++latitute; return *this; } [/code] This creates a new object and returns it. [B]1.[/B]Wouldn't it be more efficient to return a reference? [B]2.[/B]This …

There are a couple of tutorials [URL="http://www.cprogramming.com/tutorial.html"]here[/URL].

Just a bit of advice. No one is going to download all these files. You should provide the code with the errors and try to explain. Help us to help you.

Try adding header guards in header.h [code=C++] #ifndef HEADER_H #define HEADER_H #include <iostream> // put your includes in the header file so you don't need to include them in every file that uses this header #include <...> class blah_blah { }; ... #endif [/code]

[code=C++] int MAX_NUM = 600851475143; int max = 0; vector <int> ints; for(int i = 1; i <= MAX_NUM; ++i) if((int)MAX_NUM % i == 0) ints.push_back(i); cout << "size = " << ints.size(); [/code] I get 0. Something is wrong. I get 2 warnings: warning C4305: 'initializing' : truncation from …

Why don't you write this program and see the results?

Show some effort first and then people will help you. Don't expect others to do [B]your[/B] work. Just an idea: The class could contain a [B]static pointer[/B] that would point to the last element. You could set it in the constructor.

[code=C++] int input; const int ANSWER = random_integer1 + random_integer2; do { cin >> input; // get input } while(input != ANSWER); /* this will repeat as long as input is not equal to the answer. when the correct value is entered, the loop won't run */ cout << "Well …

You can have functions in Cargo that return the details and don't change any value. [code=C++] class Cargo { public: int get_weight() const {return weight;} // the const here means that this function cannot change anything from the class int get_height() const {return height;} int get_width() const {return width;} /* …

[QUOTE=Ancient Dragon;737748]when using character arrays the == operator does not compare string content but string addresses, so it will never work.

Hi. I made some headers I want to include in every project from the include directories. So I'll be able to do [I]#include <hello.h>[/I] instead of [I]"hello.h"[/I], and I won't need to place them in the same directory every time. So I did this: [IMG]http://i38.tinypic.com/2n1bdj8.jpg[/IMG] [IMG]http://i34.tinypic.com/33a4d1g.jpg[/IMG] but it doesn't work. …

[code=C++"] int x[5]; x[4] = 10; *(x + 4) = 10; [/code] Array indexing has a cleaner syntax but (as I've read) pointer arithmetic is faster. My question is, is it worth to use pointer arithmetic? Is there a noticeable difference?
