N=2 to switch moves control to case 2:

where value of sum will become 2+1=3

as there is no break so all statement below it will be executed
so now case 3: will be executed n sum will hold value 3*2=6

now break is used so control will move out of loop i.e. switch case

P is a pointer to the int variable i and *p prints the value stored in the address (of i) which it points. So answer will be 1 but data type is float so it will print 1.000000.

An lvalue is an expression to which a value can be assigned. The lvalue expression is located on the left side of an assignment statement, whereas an rvalue is located on the right side of an assignment statement. Each assignment statement must have an lvalue and an rvalue. The lvalue expression must reference a storable variable in memory. It cannot be a constant.

Lvalue is is a memory location,whose value is not constant i.e it's value is changed when a new value entered into that location.And also it can be say as, it is an expression,where  left side we have an identifier and right side(rvalue) the value.

The Answer is 2. printf function returns the number of characters printed, so it returns 3 and "tim" is already printed due to the call to printf("tim"). So the output is tim 3.

Here, x = 20; & y = 35; given, x= y++ + x++; so in this case, first we put the value of variables, x = 35+ 20 = 55 but here, x is increament so,we have to find the value of x, therefore, x++= 20+1=21, so, x = 35+21 = 56 . so the answer is 56.its correct..

Q. Difference between "C structure" and "C++ structure".
Ans:- C structure cannot have member functions but C++ structure can have. Also in a C structure by default all data members of structure are public and access cannot be changed by specifying the private or protected keywords but in C++ eventhough by default members are public we may change the access using the keywords private and protected.
Q. What is the difference between "overloading" and "overridding"?
ans:- Overloading is a process of having the same function name but different no of arguments or types of arguments within the same class but overriding means redefining a baseclass functions definition in the subclass.
Q. Explain the need for "Virtual Destructor".
Ans:=Virtual destructor ensures destruction of subclass and base class objects in proper order.
Q. What are the different types of polymorphism?
Ans:-Overloading and overriding.
Q. What are the different types of Storage classes?
ans:-Auto,Register,static and extern
Q. What is the difference between "calloc" and "malloc"?
Ans:- calloc and malloc are used for dynamic memory allocation. Calloc initializes the memory locations to zero by default but malloc memory contains garbage values.
Difference between "printf" and "sprintf".
printf will write to the console. sprintf will write to the buffer
