constructor failed??? [modified]

[CPallini]

You made a mistake in the default constructor. Can you spot it? BTW: The correct method is

class aa
{
public:
aa():x(5)
{
}
//...
};

(excluding << and >> operators usage!) He creates a temporary object (calling aa(5)) inside the default constructor, probably he wanted to initialize x with 5 instead. :)

He creates a temporary object (calling aa(5)) inside the default constructor (leaving garbage inside x), probably he wanted to initialize x with 5 instead. :)

Is This program working ???

cout>>x>>endl;
cin<<ch;

try using debuging than you find that why x is not giving right output :) #include "stdafx.h" #include <iostream> using namespace std;

class aa
{

public:

	aa(int t = 5)
	{
		x = t;
	}
	void print()
	{
		cout<<x <<endl;
	
	}
private:
	int x;

};
int main(int argc, char* argv[])
{
aa t;
t.print();
cout<<"---------------------"<<endl;

aa t1(4);
t1.print();
char ch;
cin>>ch;


return 0;

}

Thank you Pallini.I got it... But i found this code can't work. class aa { public: aa():x(5) { }//... }; it said x(5) is not a base class. Thanks once again! :)

you're not serious, are you ? :~ X| when you don't know what you're talking about, please avoid posting crap, that will avoid the question poster to be confused at last.

Thans Shilpi. I'm so sorry.It's my fault. I have edited my post... :)

[toxcct]

it's because in this class, you don't define a x member...

Sorry toxcct.It's my fault. I have edited my post. Thanks youtoxcct.

In my sample

//...

was the concise notation for

aa(int t)
{
x = t;
}
void print()
{
cout << x << endl;
}
private:
int x;
};

Its ok dealon :) He also dont know about this.

[toxcct]

nope. i still don't understand why you used the wrong operators... cout use <<, not >>

Actually he write the wrong code and I just do write his wrong code to explain him where he is wrong.:) I just explain him that his code is not working. LOL :laugh:
