nevertheless, they all tend to have the overall macro-architecture described in the figure below: Interpreter ● In computer science, an interpreter is a computer program that directly executes instructions written in a programming or scripting language, without requiring them previously to have been compiled into a machine language program ● The interpreter converts the high-level program into an intermediate language it then executes, or it can translate the source code at the high-level and then directly execute the commands, which is done line by line or statement by statement (Anon., n.d.) 8|Page Types of programming language ● There are many types of programming languages available in the market All of these different types of programming languages have their own functionalities and specialties Depending on the functions and abilities of these languages, they are classified into three main types + Machine language + Assembly language + High-level language 9|Page ● A high-level language is a programming language designed to streamline programming for computers It is called high-level because the central processing unit (CPU) of a computer is quite a few steps away from the original code running on High-level source code consists of easy-to – read structures which are then translated into a low-level language which can only be perceived and executed by a specific CPU ● A low-level language is a programming language that deals with elements and limitations of a computer’s hardware It either has an insignificant level of abstraction when referring to a machine or no level of abstraction at all, and it operates to manage the operational meaning of a machine II Procedural Programming What is Procedural Programming ● Procedural Programming may be the first programming paradigm that a new developer will learn Fundamentally, the procedural code is the one that directly instructs a device on how to finish a task in logical steps This paradigm uses a linear top-down approach and treats data and procedures as two different entities Based on the concept of a procedure call, Procedural Programming divides the program into procedures, which are also known as routines or functions, simply containing a series of steps to be carried out Simply put, Procedural Programming involves writing down a list of instructions to tell the computer what it should step-by-step to finish the task at hand Definition ● Procedural programming is a programming paradigm using a linear approach or a top-down one To perform computations it relies on procedures or subroutines ● Procedural programming is also known as imperative programming Functions ● Procedural programming is intuitive in the sense that the way you would expect a program to work is very similar to that If you want to something to a computer, you should give step-by – step instructions on how to it Moreover, most of the languages used to program early on are all procedural FORTRAN, COBOL, and C, which have been around since the 1960s and 70s, are examples of procedural languages ● It is also uses a list of instructions to tell the computer what to step by step 10 | P a g e • Explain flow chart: ➢ Step 1: START ➢ Step 2: use a for loop variable run i to check the character with the condition i
