    Develop a program that calculates Loan in C++. Your program should satisfy the following requirement:
    User Input:
    1 User is asked to enter name.
    2 User is asked to enter number of dependent with range (0-5).
    3 User is asked to enter status i.e. (Permanent or Probation).
    4 User is asked to enter Salary.
    5 User is asked to enter Duration at Job (in years):
    o <1
    o 1-2
    o 2-4
    o 4-7
    o >7
    6 User is asked how much loan is required.

    Criteria:
     Loan can be given if and only if a person is on Permanent job for more than 1 years.
     Minimum salary from which a loan can be given is 35,000 per month for a person having no
    dependent. Minimum salary requirement increases by 20,000 per dependent.
     If years of services is from 1 to 2 years, then max loan amount can be up to 6 salaries.
     If years of services is from 2 to 4 years, then max loan amount can be up to 8 salaries.
     If years of services is from 4 to 7 years, then max loan amount can be up to 10 salaries.
     If years of services is from 7 to 10 years, then max loan amount can be up to 12 salaries.
     If years of services is more than 10 years, then max loan amount can be up to 24 salaries.
     Add 13% interest on the approved loan amount. This amount will be payable within 8 years’
    time i.e. 96 months.
     If the money to lend is more than the lend amount, then calculate the difference and show it
    properly.
     For unsuccessful Loan Application: Show Message: “CUSTOMER NAME, your lend
    application has not been successful this time”.
     For Successful Loan Application: Show Message: “Congratulations CUSTOMER NAME, your
    lend application is successful this time. Your monthly installment will be ______ Amount
    Payable for 96 months”.

    Q1. Show that the following pairs of regular expressions define the same language over the alphabet

    L = {p, q}.

    (i) (pq)p and p(qp)
    (ii) (p* + q)* and (p + q)*
    (iii) (p* + q*)* and (p + q)*
    [15 marks = 5*3]

    Solution:
    (i) (pq)p and p(qp) represents same language.
    Both will never generate pp’s and both are starting and ending with p

    (ii) (p* +q)* (p+q)*
    (p*)+ q p* + q*
    p* + q* p* + q*
    Both are all strings possible in L = {p,q}

    (iii) (p* +q*)* (p+q)*
    (p*)* + (q*)*
    p* + q*
    (p + q)* Language with all strings

    Q2. Write a regular expression for the following language over the alphabet L = {x, y} such that it accepts all strings in which the letter y is never tripled. This means that no word contains the substring yyy. [5 marks]

    Solution:

    The required R.E will be
    (˄ + y + yy) (x + xy + xyy)*
