                 E.  Application Based Questions.
                    1.  Write a program to accept the name and age of a user and display it in the following format:
                       Name: Abeer
                       Age : 6

                        Assertion and Reasoning Based Questions


                       The following questions are assertion(A) and reasoning(R) based. Mark your answer as
                      a.  Both A and R are true and R is the correct explanation of A
                      b.  Both A and R are true and R is not the correct explanation of A
                      c.  A is true but R is false
                      d.  A is false but R is true
                    1.  Assertion(A):  Python considers user input as strings
                      Reasoning(R):  An INPUT() is used to accept user input from the keyboard.
                    2.  Assertion(A):  Comments make the program lengthier.
                      Reasoning(R):  Comments are ignored by the Python interpreter during execution.
                    3.  Assertion(A):  An operator specifies the operation to be performed on the given operands.
                      Reasoning(R):  An operand may be a constant or a variable.
                    4.  Assertion(A):  Evaluating the following expression:
                                   max('Anshul', 'Mridula', 'Shekhar', 'Ashish')
                                   will yield 'Shekhar'.
                      Reasoning(R):  max() takes only numeric values as arguments.
                    5.  Assertion(A):  Python allows the conversion of data from one data type to another.
                      Reasoning(R):  int() is an example of a type conversion function.

                    1.  Zorawar likes to work with numbers. He has just started working in Python and wants to perform the following mathematical
                      operations using a Python program. He wants to accept two numbers and display their sum,   difference,   product,   quotient,
                      and remainder. Help him complete his task.
                    2.  Anish is a very naughty boy. His friend, Shankar wrote a program to accept 5 numbers and display each one of them in a
                      single line, separated by a '$' symbol. The program is as follows:
                      num1 = int(input('Enter a number'))
                      num2 = int(input('Enter a number'))
                      num3 = int(input('Enter a number'))
                      num4 = int(input('Enter a number'))
