    and WHAT IS the error occuring dude ?! :doh: BTW, i see a problem in your cout statements. cout cannot 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...

    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. :)

        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!

        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();

        char ch;
        cin>>ch;
        
        
        return 0;

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

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

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