Question: (Calculator Using Function Pointers) Using the techniques you learned in Fig., create a text-based, menu-driven program that allows the user to choose whether to add, subtract, multiply or divide two numbers. The program should then input two double values from the user, perform the appropriate calculation and display the result. Use an array of function pointers in which each pointer represents a function that returns void and receives two double parameters. The corresponding functions should each display messages indicating which calculation was performed, the values of the parameters and the result of the calculation.
Write a program in c++ that takes 100 number in an array and add them and print the sum
Read the information for one purchase into a variable of your struct type. Calculate the price per item for that purchase. Output the data in formatted columns (as in program #1). Add the item cost into a total cost variable.
Create a Friend class that contains a first name, last name, a birthday, and a telephone number. Create a Contacts class that contains an array of Friend as well as the owner's name and cell phone Number.
The main program should instantiate an instance of the class Rectangle and then make calls to the member functions to input the data and output the results
Write a program that right-justifies text. It should read and echo a sequence of left-justified lines and then print them in right-justified format.
Provide an example of a program that contains an algorithm whose Big-Θ is exponential. Clearly explain what n represents in your program. Make some assumption about how long it would take to execute one of the operations that you are counting.
Given the integer variables yearsWithCompany and department , write an expression that evaluates to true if yearsWithCompany is less than 5 and department is not equal to 99 .

Make a class EMPLOYEE with a name and salary. Make a class MANAGER inherit from EMPLOYEE. Add an instance field, named DEPARTMENT
Inheritance and Polymorphism
List the vertices in graph A in the reverse order of their visit (finish) time for a depth-first search that starts at vertex A. Repeat the process, and produce a different list by assuming that the scan accesses neighbors in a different order.
