anybody correct my errores

in

Car() {
water=0.0; fuel-0.0;
oil=0.0; engine=0;
}

change

fuel-0.0

to

fuel = 0.0

notice this mistake:

float getfuel()
{ return fuel;}
};

the last line

};

is wrong, it ends the class!! this means all the functions after it are not part of the class.

remove that thing!

so change this:

float getfuel()
{ return fuel;}
};

void start()
{
cout<<"enter 1 for on/0 for off\n";
cin>>engine;
if(engine=1)
cout<<"engine started\n";
}

to this:

float getfuel()
{ return fuel;}

void start()
{
cout<<"enter 1 for on/0 for off\n";
cin>>engine;
if(engine=1)
cout<<"engine started\n";
}

now, you need to put this AFTER the stope() and BEFORE main() function.

inside main, you have to create a car object like this:

Car car1;

for example, you can name it anything you like, but I called it car1

now, in the switch-case thing, call the methods against the car1 object, like this:

switch(choose)
{
case 1:
car1.start(); break;
case 2:
car1.drive(); break;
case 3:
car1.stope(); break;
case 4:
car1.filltank(); break;
case 5:
car1.service(); break;

There is still a problem, you need some loop around the switch-case statement so that the program doesn't end until the user enters 6

there are few other errors like cout >> instead of cout << but anyway here's a fixed version:

,

class Car {
private:
float water;
float fuel;
float oil;
int engine;
public:
Car() {
water=0.0; fuel=0.0;
oil=0.0; engine=0;
}
void set_water(float w)
{
water=w;
}
void set_fuel(float f)
{
fuel=f;
}
void set_oil(float o)
{
oil=o;
}
void set_engine(int e)
{
engine=e;
}

float getwater()
{return water;}
float getoil()
{return oil;}
int getengine()
{ return engine;}
float getfuel()
{ return fuel;}

void start()
{
cout<<"enter 1 for on/0 for off\n";
cin>>engine;
if(engine=1)
cout<<"engine started\n";
}
void drive()
{
float w1,f1,o1;
float distance;
w1=distance*1;
o1=distance*1;
f1=distance*1;
cout<<"distance=";
cin>>distance;

if(f1>fuel)
cout << "go to petrol station\n";
if(o1>oil)
cout << "there no\n ";
oil=oil-o1;
water=water-w1;
fuel=fuel-f1;
}
void filltank()
{
set_fuel(100);
}
void service()
{
set_oil(100);
set_water(100);
}
void stope()
{
engine=0;
cout<<"good bye\n";
}

};

void main()
{
	Car car1;
	int choose;

	do
	{
  cout<<"please choose one of these:\n 1 to start\n 2 to drive\n 3 to stop\n 4 to fill tank\n 5 to service\n 6 to exit\n";
  cin>>choose;
  switch(choose)
  {
  case 1:
  car1.start(); break;
  case 2:
  car1.drive(); break;
  case 3:
  car1.stope(); break;
  case 4:
  car1.filltank(); break;
  case 5:
  car1.service(); break;
  case 6:
  cout<<"thanks\n";
  default:
  cout<<"errore\n";
  }
	}	while( choose != 6 );

}

now, there are still some bugs, but I'm not sure how to fix them because I'm not sure what you were trying to do, look in this function:

void drive()
{
float w1,f1,o1;
float distance;
w1=distance*1;
o1=distance*1;
f1=distance*1;
cout<<"distance=";
cin>>distance;

if(f1>fuel)
cout << "go to petrol station\n";
if(o1>oil)
cout << "there no\n ";
oil=oil-o1;
water=water-w1;
fuel=fuel-f1;
}

float distance is being used without being initialized, I'm not sure what you were trying to do, maybe you should put this

cin >> distances;

before you use it, but I'm not sure

hope that helps :)

i but my proplem and i'm sure that u will answer me(95%(

thanx alot about your help it is very useful to me and now there is7 ;)

errores instead of 15 :rolleyes:

i don't know why

as you said that function (drive) and start had errores i don't know what's the rong with them :wacko:

in function (drive) i'm trying to cheack if the oil&fuel&water is ok to cut away the distance

and in fuction start mybe can i delet the 2first stepes(cout&cin)it's ok

i don't know please can you cheak it again

thanx alooooooooot to help me :rolleyes:

my name is sara

thanx again

OK Sarah

I don't know why you are still getting errors, the code I posted above compiles with no errors with me.

anyway, I just noticed another error, in start:

if(engine=1)

should be

if(engine == 1)

I think the engine should be a bool instead of an int, but that's no big deal ..

You shouldn't ask for on or off, the start is obviously on .. so just make it

engine = 1;

for the drive method, you first need to make sure that the engine is on, so you might add something like this:

	if( engine == 0 )
	{
  cout << "can't drive when engine is off\n";
  return;
	}

also, you should ask for distance before makinig other calculations, so here's a fixed version:

void drive()
{
	if( engine == 0 )
	{
  cout << "can't drive when engine is off\n";
  return;
	}
	float distance;
	float w1,f1,o1;

	cout<<"distance=";
	cin>>distance;

	w1=distance*1;
	o1=distance*1;
	f1=distance*1;


	if(f1>fuel)
	cout << "go to petrol station\n";
	if(o1>oil)
	cout << "there no\n ";
	oil=oil-o1;
	water=water-w1;
	fuel=fuel-f1;
}

also, notice the incomplete messege "there's no" should be "there's no oil", also, you probably need one for "there's no water".

you need a "break;" after

 case 6:
 cout<<"thanks\n";

now, for services and feul, you may need to print some messege to tell the user that services are done.

void filltank()
{
set_fuel(100);
cout << "Fuel is now full\n";
}
void service()
{
	set_oil(100);
	set_water(100);

	cout << "Oil now ok\n";
	cout << "Water now ok\n";
}

same for driving:

	cout << "Drove " << distance << " kilometers \n";

same for start

void start()
{
	engine = 1;
	cout << "Engine is On\n";
}

now, I added these changes to your code, thsi code compiles with no errors with me, if you get any error messege, post it here .. the only thing I didn't write here is the

#include <iostream>

using namespace std;

but I might as well include it!

so here you go:

#include <iostream>
using namespace std;

class Car {
private:
float water;
float fuel;
float oil;
int engine;
public:
Car() {
water=0.0; fuel=0.0;

{

}
void set_fuel(float f)
{
fuel=f;
}
void set_oil(float o)
{
oil=o;
}
void set_engine(int e)
{
engine=e;
}

float getwater()
{return water;}
float getoil()
{return oil;}
int getengine()
{ return engine;}
float getfuel()
{ return fuel;}

void start()
{
	engine = 1;
	cout << "Engine is On\n";
}
void drive()
{
	if( engine == 0 )
	{
  cout << "can't drive when engine is off\n";
  return;
	}

	float distance;
	float w1,f1,o1;

	cout<<"distance = ";
	cin>>distance;

	w1=distance*1;
	o1=distance*1;
	f1=distance*1;

	cout << "Drove " << distance << " kilometers \n";


	if( f1 > fuel )
  cout << "go to petrol station\n";

	if( o1 > oil )
  cout << "there's no oil\n";

	if( w1 > water )
  cout << "there's no water \n";

	oil = oil - o1;
	water = water - w1;
	fuel = fuel - f1;
}
void filltank()
{
set_fuel(100);
cout << "Fuel is now full\n";
}
void service()
{
	set_oil(100);
	set_water(100);

	cout << "Oil now ok\n";
	cout << "Water now ok\n";
}

void stope()
{
engine=0;
cout<<"good bye\n";
}

};

void main()
{
Car car1;
int choose = 0;

do
{
 cout<<"please choose one of these:\n 1 to start\n 2 to drive\n 3 to stop\n 4 to fill tank\n 5 to service\n 6 to exit\n";
 cin>>choose;
 switch(choose)
 {

 case 6:

 cout<<"errore\n";
 }
} while( choose != 6 );

}

THANX HASSAN VERY MUCH TO HELP ME

I CHEAK IT AND NO ERRORES INSTED OF #INCLUDE<ISOTREAM.H>

(.H)IS MISSED

when i cheak it before i forgot write the hidder file & (==) it is simple mistake but it makes the errores

thanx again :rolleyes:

thanx :rolleyes:

you are the bist ;)
