double harga;

char model[25];

};

1. Declare variable ACER to be of type Komputer and array HP[10] to be of type Komputer.
   

[3 marks]

struct komputer ACER, HP[10];

1. Read a PC Price and a PC model from the keyboard into the individual members of variable ACER.
   

[2 marks]

cin>>ACER.harga;

cin>>ACER.model;

1. Assign the member values of variable ACER to element 3 of array HP.
   

[2 marks]

HP[2].harga = ACER.harga;

HP[2].model = ACER.model; //strcpy(HP[2].model, ACER.model);

DCT1063 P2 : Pointer and Array

A pointer is a variable that contains a memory address. An array is a variable that holds multiple values of the same type. In C++, there is a close relationship between pointers and arrays. In fact, frequently a pointer and an array are interchangeable.


What is output of the code above, why?

DCT 1063 ASSIGNMENT 1

1. Answer each of the following. Assume that integer numbers are stored in 4 bytes, and that starting address of the array is at location 1000 in memory. Each part of question should use the result of previous part where appropriate. [20 marks]

1. Declare an array of type integer called numbers with 10 elements, and initialize the element to the values 1,2,3,4,5,6,7,8,9,10,
   

[2 marks]

1. Declare a pointer Ptr that points to an object of type integer.
   

[2 marks]

1. Print the element of array numbers using array subscript notation. Use looping structure (for/while/do..while) and assume the integer control variable i has been declared.
   

[5 marks]

1. Assign the starting address of array numbers to the pointer variable Ptr.
   

[2 marks]

1. Print the element of array numbers using pointer with the pointer
   Ptr. Use looping structure (for/while/do..while) and assume the integer control variable i has been declared.
   

[5 marks]

1. Assuming that Ptr points to the beginning of array numbers, what address is referenced by nPtr + 9? What value is stored at that location?
   

[2 marks]

1. Assuming that Ptr points to the numbers[8], what address is referenced by nPtr -= 4? What value is stored at that location?
   

[2 marks]

2. Assume that each of the following statements applies to the same program. ( 10 marks)

a) Write a program that prompts user to enter:-

1. Name
   
2. Matric
   
3. Course
