Write a C++ program that takes five alphabets from the user and ask the user to delete any

Write a C++ program that creates an array “A” having 5 elements (in the main function). Then,

the program asks the user to enter values in this array. After that, the program should ask

question from user are you wanted to sort ascending or descending order kindly enter your

choice that’s you want to search in the array, also compute the sum of array for the ascending

order and difference of array for the descending order.

Create a class called Rational for performing arithmetic with fractions. The result should be stored in reduced form. Use integer variables to represent the private data of the class— the numerator and the denominator. Provide a constructor that enables an object of this class to be initialized when it’s declared. The constructor should contain default values in case no initializers are provided and should store the fraction in reduced form. For example, the fraction would be stored in the object as 1 in the numerator and 2 in the denominator. Provide public member functions that perform each of the following tasks:

The result should be stored in reduced form of all these parts except part (f):

a) Adding two Rational numbers.

b) Subtracting two Rational numbers.

c) Multiplying two Rational numbers.

d) Dividing two Rational numbers.

e) Printing Rational numbers in the form a/b using << operators.

f) Printing Rational numbers in floating-point format using << operators.
