Thread: overloading an operator

hello all I'm yet again stumped by the programming jargon used by my book. The question I have is what do they mean when they say that they are overloading an assignment operator thank you very kindly. I appreciate any feedback thanx.

i think i might know what you mean. I may also make you want to smash your head on a rock for not understanding what you mean . Overloading in my (mental) book goes something like follows:

(a function in a class or something)

doSomething(int i, float f) //this is normal
{
(code for doing something with i and f)
}

doSomething(float i, float f, int t) //This is overloading the doSomething function)
{
(code for doing something with i, f, and t)
}

//in other words, overloading means creating a function made for certain parameters, and then making another function WITH THE SAME NAME, but different parameters.

whoa take it easy there cowboy here is what I mean

Code:

#include <iostream.h>
#include <iomanip.h>

class Car
{
private:
	char bodystyle[5];
	int colorcode;
	int engsize;
	
public:
	Car(char[5]="xxxxx",int=0,  int=0); //constructor function with defaults
    cartype(char,int, int); //member function to copy car info
	void showcar(void);
};

//implementation section
Car::cartype(char bod[5], int code,   int eng)
{
	bodystyle[5]=bod[5];
	colorcode=code;
	engsize=eng;
		
}


void Car::showcar(void)
{
int enginesize;
cout<<"The car is";

cout<< setfill('0')
    <<setw(2) << bodystyle << ":"
	<<setw(2) << colorcode << ":"
	<<setw(2) << enginesize ; 
cout<<endl;
return;
}
int main()
{
	Car a, c("xxxxx", 2 , 1);
	

	

	cout<<endl;
	
	a.showcar();
	
	c.showcar();
   
	cout<<endl;

	return 0;
}

everytime I run this bit of code I get a funky error message saying
overloaded member function 'int (char [],int,int)' not found in 'Car'
I just need to know where I've gone wrong any help would be much
appreciated

no clue... sorry

That's overloading a function.

Overloading an operator is different. And something which I still need to learn.

i realized my error when he posted the code, but prehaps you need to put

Car a("xxxxx", 2 , 1), c("xxxxx", 2 , 1);

but then again, my brain has been muddled up in C++ since learning java, which i am still confused about the reasons for learning it (java's speed < snails)

Code:

//implementation section
Car::cartype(char bod[5], int code,   int eng)
{
	bodystyle[5]=bod[5];
	colorcode=code;
	engsize=eng;
		
}

1. Is this suppose to be your constructor definition? Your class name is Car and not cartype.

2. if it is not the constructor, it should have the return type.

3. i dont think "bodystyle[5] = bod[5]" will do what u want
