d. All coding questions should be answered using the C ++ syntax. You are allowed to use the Dev-C++ compiler to write and test your code. If you do so please remember to copy and paste your code into the examination solution area. (Do NOT share your code; your

colleague could get higher marks than you!!)

Q3. Marks : 10

Write a program that uses a function multiple(int,int) that determines for a pair of integers whether the second integer is a multiple of the first. The function should take two integer arguments and return 1 (true) if the second is a multiple of the first and 0 (false) otherwise. Use this function in a program that inputs a series of pairs of integers.

o

is used to declare objects or variables

o

can not create and initialize an object

o

names an object or variable

o

o

can allocate an appropriate amount of memory for an object or variable returns an address to an object or variable

Q5. Marks : 08

Q6. Marks : 20

Create a class named Account, its data members are

i. Account NO · ii. Account Title · iii. Balance

a) Create the object of this class using parameterized constructor in order to initialize all the three data members i.e. Account NO. Account Title. Balance

b) Write a member function of this class named deposit (), this function will calculate the current balance for the user's account. In deposit function user will be prompted to enter the amount to be deposited and displays the incremented balance.

c) Write an other member function of this class named addToFile(), In this function write the values of the data members Account NO, Account Title and Balance in the file named Account.txt.

Also write the getter and setter functions for the data members of this class
