I cant find the error

whats wrong with this progam

Code:

---

#include<iostream.h>
class carADT{
private:
static int fuel,water,oil;
public:
 carADT();
 carADT(int ff=1000,int ww=1000,int oo=1000);
 int swOn();
 int drive();
 int stop();
 int setspeed();
 void service();
 void fillTank();
 };
 carADT::carADT(){
 fuel=water=oil=0;
 }
 carADT::carADT(int ff,int ww,int oo){
 fuel=ff;
 water=ww;
 oil=oo;
 }
 carADT::int swOn(){
 cout<<"you can drive now:\n";
  return 1;
 }

 carADT::int drive(){
 carADT d;
 int x,z;
x=d.swOn();
d.setspeed();
if(x==1){
 while((z=d.stop)!=0){
 for(int c=1000;c>0;c--){
  fuel--;
  water--;
  oil--;
  }}}
  if(fuel==water==oil==0)
  return 1;
  else
  return 0;
  }
  carADT::int stop(){
  carADT s;
  int z;
  w=s.speed();
  z=s.drive();
  if(z==1||w==0)
  return 0;
  else{
  s.switchOn(0);
  return 1;
  }
 carADT::int setspeed(){
 int sp,spd=0;
 cout<<"what is the speed you want:\n"<<endl;
 cin>>sp;
 while(spd!=sp){
 spd++;
 cout<<"the speed is "<<spd<<endl;
 }
 if(sp==spd==0)
 return 0;
 }

 }

Please use [code][/code]Tags

How about this: YOU tell US what's wrong. Then post again. We can't waste our time sifting through pages of code. Narrow it down a bit.

Use code tags.

This I belive is wrong,

Code:

---

carADT::int drive(){

---

try this instead

Code:

---

int carADT::drive(){

---

Wouldnt hurt to add error message.

Or,

1. get school assignment
2. read it through once
3. post on cprogramming.com for answer

To repeat Salem's point...

Here's something I posted last month:

Start small... Just write enough code so that it compiles. Add a little code at a time, test-compiling and test-running as you proceed. This way you will know right away where the problems are.

It takes a bit of practice to learn how to sequence your program development so that it's testable as you go along. Usually, the user interface, or input/output is started first (but maybe not finalized) so you can see what your program is doing.

Programming is difficult, and every programmer test-compiles and test-runs during development. Beginners should test-compile every line or two! More experienced programmers might only test-compile every "page" or so, depending on how familiar they are with the particular functions they are using, etc.

---

If you test run each line wouldn't you get an error every line until the main closing bracket?

You build a basic skeleton, beginning with the your nice 'int main() { }' (preferably with some extra whitespace). Once you have a functional skeleton, you add functionality a couple lines at a time and recompile.

Oh ok. I think I'm going to try that sometime.
