Snake Game problem
 

I have written a snake game. There are 2 levels in the game(I
finished 1st level). It can run in VC++ without problem but, when I
run it on the dev C++ 4.9.9.2, it cannot run. I want to practice my
programming in Dev C++ rather than in VC++. What can I do now?

The Game:
--- writing a snake game using color console window.
1-player game. The player makes use of 4 arrow keys to operate the
movement
to chase and eat as much food (#) as possible. Food with a different
color has
score. The game will end when the snake hits itself or the player hits
ESC key.
-----Use link list is a must.

Thanks!

You need to post more info regarding the compilation options and the
error messages you got when you tried to compile in Dev C++, to be of
more help.

Also, the OP should post that additional info in a forum where it is
topical. Compilation options of particular compilers and the quirks of
platform specific libraries or tricks (needed for color console windows, of
which standard C++ would not know anything) do not belong here.

Owing to the file is quite a lot of code, I think I will use another
method to tell you the error. But now, I suffer a problem in Dev C++,
here is the code:
#include<iostream>
#include<iomanip>
#include<string>
using namespace std;

struct CarType{
string maker;
int year;
float price;
}

void getYourCar(CarType & car);


int main()
{
CarType myCar, yourCar;

myCar.make = "Mercedes";
myCar.year = 2008;
myCar.price = 556653;

getYourCar(yourCar);

cout << "Your car is a: " << yourCar.maker << endl;
cout << fixed << showpoint << setprecision(2) <<
"I will offer $" << yourCar.price -100 << "for your car."
<<endl;

system("pause");
return 0;

}

void getYourCar(CarType & car)
{
cout << "Enter your maker: ";
cin >> car.maker;
cout << "Enter the year: ";
cin >> car.year;
cout << "Enter the price:$";
cin >> car.price;
}

Error messages are gotten.

This code should be no problem, why it still cannot run in Dev C++?

Re: Snake Game problem
 

These is no ';' after your struct CarType definition. Does it cause
your problem?
And try to use 'void getYourCar(struct CarType & car);' instead?

Oh, you are right, it is my careless mistake.
Now , the following is my snake game's error:

There are several things in there that make this a non-standard program:
The use of color, the use of the arrow keys, and the fact that ESC need not
be followed by <Enter>. The topic cops inhibit answers to questions such as
this. There is a brand new froup devoted to solving this problem, it is
comp.lang.c++.misc. Try posting your question there and we will see if the
cure seems to work.

Um... does comp.lang.c++.misc actually exist (yet) and if so, where? It
doesn't show up on my news server or, so far as I can make out, on Google
Groups.

It was made available on individual.net yesterday. The only message so far
is an announcement (history, raison d'etre, etc) by a guy with a name I
didn't recognize. I think the new froup is a Real Good Thing, abandon this
group to the language lawyers and the green eyeshade set. Then they will
have this one and the std one and the moderated one for their "mine is
bigger than yours" talk and their endless fascination with minutiae.

The compiler told you what and where exactly is it wrong.
