OOPS ASSIGNMENT- 5
1. Create a class A with data members i and j respectively. Include a function swap () to swap the values in the data members.
2. WAP to calculate simple interest by passing the principal amount, rate of interest and time period as argument to function. Make rate of interest and time period default argument with default values 1.2 and 3 respectively
3. Raising a number n to power p is the same as multiplying by itself t times. Write a function called power ( ) that makes a double value for n and an int value for p and returns the result as double value. Use default argument of 2 for p, so that if this argument is omitted, the number will be squared. Write a main( ) function that gets values
from the user to test this function.
4 Write a function “increment” which takes two arguments and increment the first argument by second pass the argument to this function from main and print the increment value in the main function (use reference variable).

OOP ASSIGNMENT - 4
1. Write a class “employee” to store following information Name, employee ID, Age, Marital Status, and Salary. WAP to store information for 3 employees and display the results.
2. Implement a class “number” having data members value This class has a member function FindDigit() to count the occurrences of each digit in number object. Ex-If value = 1123, O/P = 1-Two times, 2 – One times and 3- One times
3.Define a class named Complex for representing complex numbers. A complex
number has the general form a + ib, where a is the real part and b is the imaginary
part (i stands for imaginary). Complex arithmetic rules are as follows:
(a + ib) + (c + id) = (a + c) + i(b + d)
(a + ib) – (c + id) = (a + c) – i(b + d)
(a + ib) * (c + id) = (ac – bd) + i(bc + ad)
Define these operations as member functions of Complex.
4. Create a string by using class , encrypt it & display it according to given instructions. A-Z, a-z, 0-9,’=’, ’,’, ’.’------- No changes. The space is replaced by ‘+’. Any other character is replaced by ‘%’ followed by ASCII value of that character.
