A. Introduction:
I. Introduction to Computer Programming Languages:
1. Definition:
Figure 1 - Computer Programming Languages
- Writing instructions for a computer to carry out one or more tasks The unique languages created for programmers are referred to as programming languages. It provides a list of coding recommendations to assist programmers in developing rules for carrying out computer operations. Each programming language has its own set of rules. (Anon., 2021)
2. Classification of Programming Languages:
- High-level Languages:
- It is the programming language with powerful abstraction which gets from software information. When the programmers use these applications, they can generate the program without permission of detailed layout of the particular machine which runs its program.
- It means that the programmers do not need to study computer design and take notice of solving the problems. Due to this, they are also called Problem-Oriented Languages.
- Examples: C, C++, JAVA… (Anon., 2009)
- Low-level Languages:
- It is the programming language with non-powerful abstraction. The programmers need to study carefully about computer design due to deep understanding of computer layout that for composing the program for such a computer.
- Not like High-level Languages, the Low-level less popular than High-level Languages.
- Examples: Assembly Language, Machine Language… (Anon., 2009)

B. Identify the program units, data and file
structures:
I. Identify the variables and data types required in the program:
Variable’s
name
Data
type
Explanation
grades [50] float Its performances grade
of students.
I choose float because
it includes real
numbers.
IDs [50] int It shows ID of students.
I choose int because it
consists of only integers.
max/min float It^ declares the biggest
and smallest mark.
I choose float because it
includes both integers and
real numbers.
maxID, minID int It shows the ID of student
who has biggest or smallest
mark.
I choose int because it
consists of integers only.
choice int It reports option that
user chooses.
I choose int because it can
be integers only.
i, j int They^ are^ used^ in^ loop
function and be numeral
number in array function,
I choose int because it can
only be integers.
n int It declares the total number
of students.
I choose int because it
cannot be real numbers.

II. Conditional statements needed in the problem
1. “Switch case” statement function:
- It is used where the expression is evaluated results in multiple values. And in my report, I use it to create multiple options which users choose to report and use in “Menu options”. 2 is to print them on the screen.
Figure 6 - Code example of “Switch case”
- With this function, my program can have more functions that users need to do with their information, such as finding the highest mark and who has that.
2. “If” statement function:
- It allows us to make a decision in the program. Moreover, it lets program to test conditions and make decision about which code block to be executed. In my program, “if” statement is used to find the highest or the lowest mark in memory that users have already inputted. Example:
Figure 7 - Code example of “If”
- In this example, min is known as the lowest mark that we need to find out. If min is higher than one element (the condition is true), min will get a new value and this new value is equal to that element.
- In this example, “Do… while” statement persuades users enter input number of students. If users enter a character, the condition is true (Check Num(n) is function that checks input as an integer and this condition is check input as not an integer) and this statement still happens. It means that users have to enter input again and again until their input is an integer.
Figure 10 - Code example of "While"
- In this example, n is the number of students. The program will print each student to the screen, one student each time. If number of students is zero, iteration constructs will be exited and end this function (n is inputted from user).
C. Design
I. WBS:
Diagram 1 - Use case Diagram
II. Flowcharts:
Diagram 3 - Display student’s information Flowchart
Step 1: Start.
Step 2: Declare float grades [50], int IDs [50], n, i=0.
Step 3: Check the condition “i < n”:
If false, the task will end.
If true, go to step 4.
Step 4: Print IDs and grades to the screen.
Step 5: Increment I by +1 and repeat step 3.
Diagram 4 - Find highest grade Flowchart
Step 1: Start.
Step 2: Declare float grades [50], int IDs [50], i, maxID, max.
Step 3: Check the condition “i < n”:
If false, print max to the screen.
If true, go to step 4.
Step 4: Check the condition “max < grades[i]”:
If true, set max = grades[i] and go to step 5
If false, go straight to step 5.
Step 5: Increment i by +1 then repeat step 3.
Step 6: End.
