constructor failed??? [modified]

Hello all. I have this code with something error occured: //------------------------------------------ #include "iostream" using namespace std; class aa { public: aa() { aa(5); } aa(int t) { x = t; } void print() { cout << x << endl; } private: int x; }; int main() { aa t; t.print();//this can't output "5", why? return 0; } ///--------------------------- As is descriped above, thanks in advance!
If we dream, every thing is possible!

and WHAT IS the error occuring dude ?! :doh: BTW, i see a problem in your
coutstatements.coutcannot use the>>operator. it uses<<operator only, so change your code into this :void print() {
cout << x << endl;
}and everywhere you're doing such a mistake...

You made a mistake in the default constructor. Can you spot it? BTW: The correct method is
class aa
{
public:
aa():x(5)
{
}

This is going on my arrogant assumptions. You may have a superb reason why I'm completely wrong. -- Iain Clarke -
Could you please elaborate the problem ? What's wrong ? And please use the "code block" option when posting code (all of that is clearly explained in the posting guidelines).

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! :)
If we dream, every thing is possible!
it's because in this class, you don't define a x member...

In my sample
//...
was the concise notation for
aa(int t)
{
x = t;
}
void print()
{
cout << x << endl;
}
private:
int x;
};:)

I think now you got the answer why i write that code. :)
Yes U Can ...If U Can ,Dream it , U can do it ...ICAN
nope. i still don't understand why you used the wrong operators... cout use <<, not >>
