You are required to develop a simple result sheet generator for an Advanced level class.

Assume that class consists of 30 students and each student follows a subject. Implement your

result sheet generator as a menu driven C++ application. Your program should read 30 students

marks from the keyboard and print mark, grade sheet and summary sheet as per the details

given below.

i. Draw a top-level design diagram for the above problem.

Draw a top-level design diagram for the above problem. ii. Write a method named ‘main_menu ()’ to display the following menu items ----------------------- Result Sheet Generator ----------------------- [1] Add New Student Marks [2] Print Mark Sheet [3] Print Grade Sheet [4] Print Summary Sheet [5] Exit iii. Use an array to store all marks of the 30 students. iv. Write a method to add_new_marks () to add marks for the 30 students.

Write a program that keeps track of a speakers’ bureau. The program should use a structure to store:

 Name

Telephone Number

Speaking Topic

Fee Required

Add functions to set the values of data members and add function show values as well,The program should use an array of at least 10 structures. It should let the user enter data into the array, change the contents of any element, and display all the data stored in the array.

The program should have a menu-driven user interface.

Search Function for the Speakers’ Bureau Program that allows the user to search for a speaker on a particular topic. It should accept a key word as an argument and then search the array for a structure with that key word in the Speaking Topic field. All structures that match should be displayed. If no structure matches, a message saying so should be displayed.

Input Validation: When the data for a new speaker is entered, be sure the user enters data for all the fields. No negative amounts should be entered for a speaker’s fee. 

Declare a structure named TempScale, with the following members:

fahrenheit: a double

centigrade: a double

Next define a Reading structure variable.

Write statements that will store the following data in the variable you defined above.

Wind Speed: 37 mph

Humidity: 32%

Fahrenheit temperature: 32 degrees

Centigrade temperature: 0 degrees 25.

showReading. It should accept a all member variable as its argument. The function should display the contents of the variables on the screen.

getFahrenheitReading, The function should return the value of Fahrenheit temperature.

getCelsiusReading, The function should return the value of Fahrenheit temperature.

recordReading. It should ask the user to enter values for each member of the structure and save the values.

findReading (int temp). It should use formulas to convert temperature into Fahrenheit and Celsius (according to user choice).

Input Validation: Add proper validation checks do not accept negative numbers for data member.

 Write an application that ask the user for a letter grade A, B, C, D, E, or Q to quit. When the user types the user Q the program must end. Display the following using the information on the table below. Use a switch statement for the selection. When the loop terminates display how many A, B, C, D, or E were entered.
