  1. LAB#3 Pointers

  2. Ex1: What is the output of the following code ? firstvalue is 10 secondvalue is 20

  3. Ex2: What is the output of the following code ? firstvalue is 10 secondvalue is 20

  4. Ex3: Pointers and Arrays (Trace) 10, 20, 30, 40, 50,

  5. Ex6:Write a C++ program that defines array b with 10 integer elements. Then the program should use pointers to reset each element in the array to ZERO.

  6. Ex7: introduce int variables x and y and int* pointer variables p and q. Set x to 2, y to 8, p to the address of x, and q to the address of y. Then print the following information: • The address of x and the value of x. • The value of p and the value of *p. • The address of y and the value of y. • The value of q and the value of *q. • The address of p (not its contents!). • The address of q (not its contents!).
