        ► Two

        ► Three


Dynamic memory allocation ky ab kuch question thay MCQ b aur 2 number ki b


Constructor enclose the other constructor and tells the how’s destructor call


For non-member operator function, object on left side of the operator may be

        ► Object of operator class

        ► Object of different class

        ► Built-in data type

        ► All of the given options



           The operator function will be implemented as _____, if obj1 drive the - operator whereas obj2 is

             passed as arguments to - operator in the statement given below.

              obj3   =   obj1 -   obj2;

      ► Member function

      ► Non-member function

       ► Friend function

       ► None of the given options




          Which one of the following is the declaration of overloaded pre-increment operator implemented as

       ► Class-name operator +() ;

        ► Class-name operator +(int) ;

        ► Class-name operator ++() ;

        ► Class-name operator ++(int) ;check from book please


 The static data members of a class are initialized _______

       ► at file scope

Es tarhan ka question tha lakin values change thee

What will be the output of following function if we call this function by passing int 5?

template <class T>

T reciprocal(T x)

{

return (1/x);

}

Answer:-

0

The output will zero as 1/5 and its .05 but conversion to int make it

zero
Above is prototype of template class so assume passing an int and
Post increment and pre increment k syntax btana thay(2 marks)

Answer:

Classname operator ++(); ---- pre increment
Classname operator ++(int) ---- post increment

Es ka pocha tha copy constructor  or assignment
Matrix m1 = m2;
How many arguments a Unary Operator take? Can we make a binary operator as unary operator?
Answer:-
Unary operator takes only one arguments like i++ or i-- (Post increment or post decrement operators for
integers) or ++i,--i (Pre increment or pre decrement operators for integers) ,we can not make Unary
operator as binary or binary as Unary operator
Simple function and class function explain


5 mark ka ak question th
To calculate the tax 5%  and 7 % to deduct the salary using the switch statement
Full concept of Midterm aur ya question book mai hay kafi ziyda milta hay lakin values change thee lakin idea same tha
5 marks ka 2nd question
-Class String
-Delete pointer
-New sy allocate memory
-Strcpy(s2,s1)

Main()

   -String  s, *sptr
   Kuch assignment ki hoi thee baki yad nahi Kai problem kahn thee aur ya likha hoa tah kai bad
   programming hay ap khud program lkihoo
   And program mai sy error findout kerny thay aur khud program batana tha kai consi technique 
  bather hhay
