I.introduction(P1,M1) We are in the twenty-first century, and the world is transitioning to the 4.0 technological era. Information technology is now widely used in everyday life, society, and the workplace. It distinguishes this industry from the rest. It also assists people in managing a variety of different aspects of their lives, such as school and industry. I shall introduce programming languages in this paper. In addition, I will offer a language for resolving user issues. I'll discuss the idea, how we use it, and how it works.
1. Secenario: A math teacher wants to manage grades of a class. He asks you to help him to write a small application to do that. He needs to enter student IDs, student’s grades and store these information into 2 separate arrays (integer array for IDs and float array for grades). Then he needs to print all student IDs together with their grades. Finally, he needs to know which student has highest grade and lowest grade. Your program should be menu based with the options above. When an option is

point. Dividing a program into functions allows many people to participate in the program's construction. Figure 6 : Simulaiton Procedural Programming 3.2 KEY FACTORS OF PROCEDURAL PROGRAMING
- Predefined functions: A predefined function is typically an instruction identified by a name. Usually, the predefined functions are built into higher-level programming languages, but they are derived from the library or the registry, rather than the program. One example of a pre-defined
function is ‘charAt()’, which searches for a character position in a string. Figure 7 : predefined function example
- Local Variable : A local variable is a variable that is declared in the main structure of a method and is limited to the local scope it is given. The local variable can only be used in the method it is defined in, and if it were to be used outside the defined method, the code will cease to work.
- Global Variable : A global variable is a variable which is declared outside every other function defined in the code. Due to this, global variables can be used in all functions, unlike a local variable.

4. USER REQUIREMENT
- Enter student IDs, student’s grades and store these information into 2 separate arrays (integer array for IDs and float array for grades).
- Print all student IDs together with their grades.
- Print highest grade and lowest grade.
- Menu based with the options above, The program will return to the main program when the program ends.
- Option to quit program. => Use C programming language to make a programing can solve the problem from a teacher. II. SCENARIO ANALYSIS(P2) 1. UNIT INITIALIZATION 1.1 Variables Variables in C languages are used to store different forms of data. It acts as a memory card where it saves all the data and used it during program execution. There are different types of variables in C; according to their types, the amount of memory or storage space it requires differs. As we said, variables
in C are storage used to hold the value. Data that variables can be different like int, float, char, double, etc. All the code or program depends on the variables as it describes the type of data for execution. 1.2 Data types Data types in c refer to an extensive system used for declaring variables or functions of different types. The type of a variable determines how much space it occupies in storage and how the bit pattern stored is interpreted. Figure 10 : Data types
- Integer data type(int): it can have a range of numbers based upon the size you choose in memory, and it can have either all positive or from negative to positive range of numbers based upon user choice of code design.
- Float data type: Any real number can be stored in the float data type, and here also we can specify the range.
- Char type: This represents the character data type, and it can be either signed or unsigned with a constant size of 1 byte for both cases.
- Void type: it won’t return anything like you saw the main function prefixed with void type in the above snippets
- Arrays: When any homogenous set of data has to be stored in contiguous memory locations, then this data type is chosen, the use case is that there may be times when your code would return more than one result, and that has to be returned from functions cumulatively
Figure 12 : Flow diagram of If statement
- if else statements: If else Statement in C programming language, when we need to execute a block of statements that too when a particular condition is met or not met that situation is known as decision making. In C programming, the decision-making process is used to specify certain orders in which statements are executed. I use if-else statement to check the condition of the data that I enter.
Figure 13 : Flowchart of If-else *Else If statement: When there are numerous criteria, the else-if statement is used to run the program. It is known as a multi-decision statement, and an else if statement and an else statement are placed after it.
Figure 15 : Flowchart of switch case 1.5 Loop statement
- Definition: Loops in C programming language is a conditional concept used for consecutively executing a line or a block of code over and over again until it reaches the value desired by the programmer. In C programming, there are three types of loops, namely For Loop, While Loop and Do While Loop.
- For loop: Infinite loops can be a series of instructions that can be carried out forever. These types of loop happen whenever there simply no terminating condition offered or possibly a terminating condition that could never be fulfilled (just like 1==2 and so on.) or maybe occasionally due to a run time error. I used it to run the loop program "i" to do the reading of the input data and i used it to run for loops looking for similar values like: MaxGrade, MaxID,...
Figure 16 : For loop flowchart
- Do while loop: but DO WHILE loops execute the Program Statements first then the condition will be checked next. DO WHILE will execute the program at first even if the condition is valid/un- appropriate/False at first. Because the input values are most likely incorrect, I used it to double check and in the MenuOption I use it to run and double check the cases in it.
