    Assignment 2

    A special two-digit number is such that when the sum of its digits is added to the product of its digits, the result is equal to the original two-digit number.

    Example: Consider the number 59.
    Sum of digits = 5 + 9 = 14
    Product of digits = 5 * 9 = 45
    Sum of the sum of digits and product of digits = 14 + 45 = 59

    Write a program to accept a two-digit number. Add the sum of its digits to the product of its digits. If the value is equal to the number input, then display the message "Special two—digit number" otherwise, display the message "Not a special two-digit number".

    Assignment 4

    Design a class to overload a function area( ) as follows:

    1. double area (double a, double b, double c) with three double arguments, returns the area of a scalene triangle using the formula:
      area = √(s(s-a)(s-b)(s-c))
      where s = (a+b+c) / 2
    2. double area (int a, int b, int height) with three integer arguments, returns the area of a trapezium using the formula:
      area = (1/2)height(a + b)
    3. double area (double diagonal1, double diagonal2) with two double arguments, returns the area of a rhombus using the formula:
      area = 1/2(diagonal1 x diagonal2)
    Assignment 5

    Assignment 6

    Using the switch statement, write a menu driven program to calculate the maturity amount of a Bank Deposit.
    The user is given the following options:

    1. Term Deposit
    2. Recurring Deposit

    For option 1, accept principal (P), rate of interest(r) and time period in years(n). Calculate and output the maturity amount(A) receivable using the formula:

    A = P[1 + r / 100]n

    For option 2, accept Monthly Installment (P), rate of interest (r) and time period in months (n). Calculate and output the maturity amount (A) receivable using the formula:

    A = P x n + P x (n(n+1) / 2) x r / 100 x 1 / 12

    For an incorrect option, an appropriate error message should be displayed.
