Assume you are employed as a senior procedural programmer in a software development company. A client is seeking for details features of procedural programming for developing their new system. Based on your experiences and solid knowledge in procedural programming, the company has decided you to prepare a detail report explaining the features of procedural programming.

1.1 There are various types of programming languages and each of them have own features and characteristics. Discuss the principles, characteristics and features of procedural programming language with an example. [P1.1, M1]

Hint: (a) short description of low-level languages, high-level languages (b) principle, characteristics and features of procedural programing (methods, loop, decision, functions, local variable, global variable, procedure, program libraries, data structures, parameter passing etc.)

To achieve M1, you must demonstrate a clear understanding of the procedural programming and other types of programming language (object oriented, event-driven etc) with relevant example. In addition, you will have met the deadline to submit the tasks and achieve the unit assessment criteria.

Scenario for LO2, LO3 and LO4

A renowned “Greenwich Primary School” hired you based on your good theoretical and practical knowledge to design, develop and testing a various mathematical program. School wants to design and develop a “Math Skills Assessment Program” for children (9 - 12 years old) with a view to understand their level in mathematics. You have to set up two types of testing methods one for to evaluate the Numeracy Skills – Mental Arithmetic and another for Problem Solving Skills. Each test must have minimum 15 questions.

The requirements and functionalities of system are given below:

Numerical Skills Test: Mental Math (NST): simple to numerical calculation including addition, subtraction, division and multiplication, time, decimals and percentage, measurement including money, distance etc. For example :

  1. 15 + ? = 25
  2. 28 + 4 = ? * ?
  3. 8 / 3 = 3 * ?
  4. Subtraction 6 from 1005
  5. 1/8 of 56 = ?
  6. 3/10 + 2/5
  7. 25% of 325 = ? etc

Problem Solving Test (PST): Simple calculation to complex (language math). for example :

  1. (-3* - 3) + (-2 -5) = ?
  2. (12 + 5 –4 * 12 / 3) = ?
  3. How much more is £5 than £2.23?
  4. If half kg of sweets costs 75p
  5. How much will 100g cost?
  6. Find the difference in cost between 4 small tins at 30p per tin and 2 large tins at 55p per tin ?
  7. Find difference of 1/6 of 30 and 6 times 30; etc

Children need to pass in both test. Pass mark is 50%. If children fail in NST then not allowed sitting in the PST test

After completing the test, the result will be displayed in the format of: name, age, gender, className, no of right answer, no of wrong answer, obtained mark, result (pass – with grade or fail), and list of wrong and right question no.

It is required to store the children information and his/her test report in the file (name, age, gender, className, test date, no of right answer, no of wrong answer, obtained mark, result and grade).

Design and develop a very simple command-based system (windows console application) including the following functionalities:

  1. System must have a login system i.e. when run the program, it should ask the user to enter username and password;
  2. User can try to login on system maximum 3 times then system automatically exit.
  3. If successful login then system will show the menu.
  4. User selection menu will be number or text based for example : [1] Child Registration or [A] Child Registration
  5. This system have five menu:
    • Children Registration
    • Numerical Skill Test
    • Problem Solving Skill Test
    • View Test Result
    • Help,
    • Exit
  6. Children Registration (Full name, age, gender, className)
  7. After registration than children can go for Numerical Skill Test – (need to ask the question one by one) and children record and test’s result (both) need to save in the file.
  8. Help: Supporting information about the system.
  9. Exit: this option should allow the user to exit the system.
View Test Result – display the children’s' test report on the screen, the required format is given below:
Greenwich Primary School
Math Skills Assessment Result

Child Name: Age: Gender: className: Test date:
Test Name Obtained Mark Result Grade .......... Numerical Skills Test: Mental Math Problem Solving Test

Note: Check, where necessary that valid data has been entered or ensure that invalid data cannot be entered.

Student is expected to produce a single program and attach a digital copy of the code in a zip file in appendix of the final assignment report. All program test output screens must be included in the report. Finally, the student will demonstrate a working program in className for oral examination within Microsoft Visual Studio / 2010 or later environment.

Assignment Task 2

Note: requirement specification, program design and technical documents

  • To achieve D3, you should demonstrate a creative and effective thinking. You need to find out additional suitable functionalities with appropriate justification, your additional functionalities must be suitable (integrate/implement) for this system.

Below are some of the common good practices generally accepted as industry standard and followed by those in industry who are using programming in general and the C/C++/C#/Java in particular. You will get more marks for following good programming practices. Some examples are given below.

  • When naming identifiers,
    • o Do not start with underscore (used for technical programming). e.g. _grades (this is bad practice)
    • o Write single word variables in all lower case , e.g. int grades, roots;
    • o Space is not allowed in identifiers, e.g. ‘student grades’ is wrong! write this as studenGrades or student_grades.  Note the use of capitalisation or the underscore.
    • o Use CAPITAL LETTERS TO DECLARE CONSTANTS, e.g. SIZE = 100 or PI = 3.14;
    • o Start function names with capital letters. e.g. AverageGrades(). Spaces are not allowed in function names. ‘Average Grades()’ is wrong. Use AverageGrades() or Average_grades().
  • Make a habit of using Meaningful identifier and Function Names to make your code easier for others to understand. Think about it, what does {"g"} mean? Is it grades, garbage, grave, etc. Thus do not use cryptic identifier names, e.g. Use ‘grades’ to refer to student grades rather than ‘g’. Similarly, use sensible function names. If you want to write a function that assigns student’s grades, then call it StudentGrades(). Do not use your names or names of your pets or any name that does not describe what the function does, but at the same time do not use more than 3 words, i.e. do not use a sentence to name a function. e.g. ThisIsMyAverageFunction() while syntactically correct is not good programming practice.
  • Remember C# is case sensitive so ‘Grades’ and ‘grades’ are not the same as identifier names. Thus be case and spelling consistent. Use an identifier name only once and spell it (upper and lower case) the same way within your program.
