University of Greenwich who provide this coursework for
students. I would like to thank to all the authors and
researchers who researched about DEV C++ program.
Moreover, I would like to present my appreciation for our
lecturer, they support me at the first, always Enthusiastic
answers to my questions , for her great and expert lectures
and guidelines. Last but not least, I would like to appreciate
responsible teachers and staffs from our centre, I’m very
proud of for providing such a good learning environment.

Chapter 2: PRINCIPLES OF PROCEDURAL PROGRAMMING
- INTRODUCTION In the past, the most of us had a lot of hard problem that it solved by conventional methods. It took to a long time or sometimes it almost can not to do. And then, computer appearance to support the humans to advanced quality of works and make the product become fast and more efficiency. Nowadays, anywhere we can see that computer an indispensable part in the life from company to learn. It make people become more modern. Figure 1.3- 1 : People and technology
- THE SPECIAL THINGS IN COMPUTER AND PROGRAM a) The speacial things in computer Computer is a programmer device that storage , it can regain and access data. The first, it was given to human who performed numerical calculations using mechanical calculators. And after, it was given to a mechanical device as they began remove the human computers. Currently, computers are electronic tool, it will accept data(input), process that data, product output and storage result. Figure 1.3- 2 : Computer
b) Computer Program Computer programming is way make computer can understand the things humans want to do. It is like a guide for computer. Guide can known as code, and computer programmers write code to solve problem or perform a specific task. Figure 1.3- 3 : Computer program c) What is coding and how can computer work? What is the coding? Code is types of coding languages used by programmer to get a computer to behave anything you want it make. If fill of full line of code, it called a script. Program develop process Step 1: Problem Definition Step 2: Program Design Step 3: Coding Step 4: Debugging Step 5: Testing Step 6: Documentation Step7: Maintenance
Chapter 3: INTRODUCTION TO PROCEDURAL PROGRAMMING
Procedural Programming can say the first that new developer will have to learn. Basically, the procedural code is the one in directly instruction a device finish a task in logical step.
1. Simple program
Content: This programming will print one line to say “Hello world” on the screen Process: We will use the “printf” command in C language to call the computer screen to print “Hello World” Figure 1.3- 5 : Flowchart of ”Hello world” Figure 1.3- 6 : Code simple program Figure 1.3- 7 : Result of simple program
2. Variable
Defenition of variable : datatype variable ; Local variable: it was laid inside a function or block. Specially, it is declared override the same variable name in the larger scope and just used with same name but different function. Global variables: global variables meanings visible and outside any function and they use it on any function in the program. Figure 1.3- 8 : Global and variables Global variables are declared outside any function, and they can be accessed (used) on any function in the program. For example, variable a in line 4 is a global variable, and then it can be accessed by all the function in the program Local variables are declared inside a function, and can be used only inside that function. It is possible to have local variables with the same name in different functions. For example, b in line 9 is a local variable and then it can be accessed only inside the function my_test(). Even the name is the same, they are not the same. It's like two people with the same name. Even the name is the same, the persons are not.
Figure 1.3- 11 : If statement Figure 1.3- 12 : code if statement Explanation: See if check my target my subject just equal 5, if it is, the subject is pass or not, the subject is fail c) Switch case statements Definition: The switch case statements is used when we have multiple options and we need to perform a different task for each option.
Figure 1.3- 13 : Switch case statement Example: it’s very useful when you out of the switch body. Whenever “break” statement is encountered in the switch body, the control comes out of the switch case statement. Figure 1.3- 14 : Code switch-case
Figure 1 .3- 17 : While loop statement Do While loop: Definition: The do while loop is similar while loop, but the condition is checked after the loop body is execute. This ensure that the loop is run at least once Example: print a table of number 2 using do while loop Figure 1.3- 18 : Do while loop statement
4. Function
Definition: A function is a block of statements that performs a specific task. Suppose you are building an application in C language and in one of your program, you need to perform a same task more than once Function declaration syntax: return_type function_name( parameter list ); Figure 1.3- 19 : Function declaration syntax Type of Functions: 2 types Standard library functions User-defined functions Figure 1.3- 20 : Library function and user-defined function
5. Value passing (parameter)
A value parameter is a formal parameter identification a memory location that is set aside while the procedure is dynamic, and into which the contents of an actual parameter will be copied at the time the procedure is called
6. Parameter passing (Pointer)
There are different ways in which parameter data can be passed into and out of methods and functions. Important of method Parameter passing
Chapter 4: DESIGN PROCEDURAL PROGRAMMING SOLUTIONS
1. Identify Input, Output
a) In/Out variables Input variables struct student(): to store the object name student with the information as id and grades struct StudentDetail { o Int id; o float grade; }typedef StudentDetail; Int id: IDs of student Float grade: Grade of student StudentDetail student[100]: to store information of list of student Output variables List information of all student Information student with finding by ID Student information who has the highest grade Student information who has the lowest grade b) Main Variables Int for choice: get input user choice from menu Int for n: to store count of list friend Int for index: input index search information Int for id: input id search information Figure 1.3- 22 : Main variables in function
c) Switch case/selection variables Figure 1.3- 23 : Choice menu function Use the switch case to declare the integer value to get the user’s choice from the keyboard and process. A menu must use a switch case because there are too many different options for menu.
d) Sub functions and hierarchy diagram of the program
Function input ID: Local variable: int id Figure 1.3- 24 : input ID Function Function inputgrade: Local variable: float grade Figure 1.3- 25 : Input local variable function
