Pointer: Pointer will allow the user to indirectly access and manipulate the variable data contents. A pointer variable will hold the address of the data contents. If an asterisk “” operator is present before the variable then that variable is referred as pointer variable. An asterisk “” is also referred as indirection operator is used to dereferences the pointer. Adding a value to a pointer variable: When a pointer variable is added, it is similar to adding number of time the size of the pointer variable that is stored. Example: //declaring a pointer variable int a; //incrementing the pointer value by 1 a++; In the above snippet the pointer variable is incremented by “1” means, the size of the pointer variable is being increased in terms of their size. 1 2 = 2 Therefore, additional of 2 bytes will be added to the pointer variable “a” after incrementing it by one.

Chapter 10, Problem 16RQE

Program Plan Intro

Pointer:

Pointer will allow the user to indirectly access and manipulate the variable data contents. A pointer variable will hold the address of the data contents. If an asterisk “” operator is present before the variable then that variable is referred as pointer variable. An asterisk “” is also referred as indirection operator is used to dereferences the pointer.

Adding a value to a pointer variable:

When a pointer variable is added, it is similar to adding number of time the size of the pointer variable that is stored.

Example:

//declaring a pointer variable

int a;

//incrementing the pointer value by 1

a++;

In the above snippet the pointer variable is incremented by “1” means, the size of the pointer variable is being increased in terms of their size.

1 2 = 2

Therefore, additional of 2 bytes will be added to the pointer variable “a” after incrementing it by one.

Make the following game user friendly with GUI, with some simple graphics. The GUI should be in another seperate class, with some ImageIcon, and Game class should be added into the pane. The following code works as this: The objective of the player is to escape from this labyrinth. The player starts at the bottom left corner of the labyrinth. He has to get to the top right corner of the labyrinth as fast he can, avoiding a meeting with the evil dragon. The player can move only in four directions: left, right, up or down. There are several escape paths in all labyrinths. The player’s character should be able to moved with the well known WASD keyboard buttons. If the dragon gets to a neighboring field of the player, then the player dies. Because it is dark in the labyrinth, the player can see only the neighboring fields at a distance of 3 units.

A cylinder of diameter 10 cm rotates concentrically inside another hollow cylinder of inner diameter 10.1 cm. Both cylinders are 20 cm long and stand with their axis vertical. The annular space is filled with oil. If a torque of 100 kg cm is required to rotate the inner cylinder at 100 rpm, determine the viscosity of oil. Ans. μ= 29.82poise
