- Objective:
- The purpose of this lab project is to expose you to structures and classes.
- Problem Specification:
- Using a structure:
- You are to write a program that will define a structure consisting of the following data members, “fields”:
- Name - a string
- Student id number – an integer.
- Three test scores – positive short integers.
- Average –a float
- Grade – a character.
- Input to the program consists of:
- name
- id number
- three test scores
- Requirements:
- Use a function to read the name, id number and three test scores, the function will return a structure.
- A function to find the average, the function is a void function that takes the entire structure as an argument (by reference) and calculates the average.
- A function that takes the average as argument and returns the grade (‘A’,’B’,’C’,’D’, or ’F’) using standard grading.
- A function that prints each data member of the structure on a separate line and calls another function that prints the message “You Passed” or “You Failed”.
- Using a class:
- You are to write a program that will define a class consisting of the following data members:
- Name - a string
- Student id number – an integer.
- Three test scores - short integers.
- Input to the program consists of:
- name
- id number
- three test scores
- Requirements:
- Must use a project with three files (a specification, an implementation, and a client file)
- Must define a null destructor, and a constructor with default arguments to initialize data members to null or zero.
- Use a setter function to read the name, id number and three test scores from the keyboard.
- A getter function that prints each data member of the object on a separate line and uses two private functions that will find the average and grade (local to print) to be printed. Print will also print “You Passed” or “You Failed”.
- All getter functions are constant with constant parameters.
- Your output, for both, should be a report like follows:
- Employee Name : Jim Donavan
- Id Number : 2345
- Tests :
- 1- 78
- 2- 88
- 3- 98
- Average : 88.00
- Grade : B You Passed.
- Grading criteria:
- Structure implementation
- 5 points Good programming practices: Proper spacing, comments, use of descriptive variables, indentation and appearance of program.
- 5 points typedef is used to define a structure and the new type is used where needed.
- 5 points every function has specifications.
- 5 points Hierarchical chart is handed-in and is correct.
- 25 points Requirements above are followed.
- 5 points test results are handed in.
- Class Implementation
- 5 points project has three files
- 3 points Guards are included.
- 2 points destructor function is defined as requested.
- 5 points constructor functions is defined as requested.
- 5 points every function has specifications.
- 5 points class diagram including access specifiers is handed-in and is correct.
- 20 points Requirements above are followed.
- 5 points test results are handed in.
- Submission Details:
- Submit a print-out of:
- The source files
- A hierarchical chart
- A class diagram
- A test run for each.
