INTRODUCTION
This report will bring to you the basic knowledge about algorithm, flowchart and the steps of developing a complete program and discuss meticulously the steps taken from writing code to execution and the relationship between the written algorithm and the code variant. It also explains 3 types of Programming paradigm and their relationships, common features of Integrated Development Environment, debugging process and code standard. Furthermore, it’s the evaluation when using and not using of an IDE, the reasons debugging process help applications more secure, robust and the important of a coding standard toward a team and the individual. Finally, it’s the implement of CIAO applications – a simulate sequence of restaurant program for indolent people to enjoy a fast, convenience and proper dinner!
Perfomed Student: Nguyen Nhat Huy 2 CHAPTER 1 Define basic algorithms to carry out an operation and outline the process of programming an application.
1.1 Definition of algorithm and Process in building an application (P1)
An algorithm is a set of clear and precise steps or rules designed to solve a specific problem or perform a particular task. Algorithms are commonly used in computer science and mathematics, but they can also be applied in various other fields
1.1.1 Problem solving and algorithm
1.1.1.1 Algorithm definition As you can see, algorithm in computer science is briefly considered as a limited sequence of steps of actions related to mathematical and deductive logic expresses the process, which can be computation, data-processing or others, of finding solution for a problem and gives the predictable result based on the initial entered data or parameters. Just simplify problems as how to make a cup of coffee. To do that, we go through steps of things such as boil the water, put power of coffee into cup, pour water and stir. We need coffee, water as the ingredients and have a fragrant cup of coffee as the result. Continue, mathematical problems can be “Print the phrase “Hello World”.”, “What is the maximum of a range?”, “Solve the first order and second order equation.”… Additional, there are several types of algorithms: Numerical algorithms. Algebraic algorithms. Geometric algorithms. Sequential algorithms. Operational algorithms. Theoretical algorithms.
Perfomed Student: Nguyen Nhat Huy 4 Figure 1.1: Step 1 of solving a life problem {1} Step 2: Marinate the chicken for at least an hour, preferably overnight. Figure 1.2: Step 2 of solving a life problem {2} Step 3: Turn on the microwave to 200 degrees Celsius and set it for about 15 minutes. Line the tray with a silver sheet and place the chicken on it neatly. Roast the chicken for about 10 minutes. Then, take the chicken out and brush another layer of honey on the outside. Continue to grill for about 10 more minutes to complete the dish Figure 1.3: Step 3 of solving a life problem {3} Step 4: Take it out on a plate and enjoy it

the program. S2: Input n (n > 1), create a variable named prd, prd = 1. S3: if n = 1 then moving to S4, else n = n – 1, prd = prd * n, continue S3. S4: Print prd to the screen. S5: End the program.
1.1.2 Flowchart
Perfomed Student: Nguyen Nhat Huy 7 (^1) https://www.lucidchart.com/pages/what-is-a-flowchart-tutorial They are related to other popular diagrams, such as Data Flow Diagrams (DFDs) and Unified Modeling Language (UML) Activity Diagrams.” 1 We can understand it simply as: In IT (Information Technology), flowcharts are a pictorial way to describe algorithms. They are highly appreciated as it is more straightforward to follow the structure though pictures than though words. In addition, it is nearly effortless to draw a flowchart which is complex and difficult and alter it into programming language. A flowchart’s basic elements are a set of symbols (containing messages) which has standard samples established for a number of different applications and interconnecting lines with arrows. 1.1.2.2 Some common symbols using in a flowchart The Oval (A beginning or an ending)
Figure 1.7: The Symbol - Oval.............................................................................................................
The oval, also referred to as terminator, is usually used to represent the start and end of a process. The shape frequently contains “Start” and “End” within. It highlights the beginning-point and finishing-point of the program. Parallelogram (Input/ Output symbol)
Figure 1.8: The Symbol – Parallelogram..............................................................................................
The Input/ Output symbol, also known as the “Data Symbol”, represents to declare variables or generated data needed for the task and show the output usually by printing commands.
Perfomed Student: Nguyen Nhat Huy 8 The Rectangle (A step in the flowcharting process)
Figure 1.9: The symbol - Rectangle.....................................................................................................
The rectangle, or the decision symbol, shows an act in your diagram. It can be a process, an action, or a function. The Diamond (Indicate a decision)
Figure 1.10: The symbol - Diamond....................................................................................................
This illustrates a question or a decision which is required to choose to move forward. This will get the value true or false, yes or no dependent on the answer or consequences thereafter. To exemplify, here is a simple command to find the minimum of 2 numbers: if a < b, min = a. In this case, the condition is “a < b”, if the value of a less than the value of b (true), the program will execute the main part by min equivalent to a, if it’s not (false), the program won’t do anything. The Arrow (Indicate Directional Flow)
Figure 1.11: The symbol - Arrow.........................................................................................................
The most ordinary use of arrow in reality is to guide humans to the destination. In a flowchart, arrows have the similar advantage which is to lead the viewer though the flowcharting
