Lesson 1 📚

Course: C++ Basics 💻

Chapter 1: What is a Program? 🤔

A program is a sequence of written instructions that a computer can execute to perform specific tasks or solve problems.

program ማለት instructions ነው። ለምሳሌ, አንደ ሼፍ የሆን ምግብ prepare ለማድረግ 🍽️, recipe እንደ ሚጠቀመው, computerም የሆነ specific task or problem solve ለማድረግ program ይፈልጋል 💡.

Programming Languages 🌐

A programming language is a tool used to communicate with computers. There are two main categories of languages:

1. Natural Languages 🌍: These are human languages used in everyday communication, such as English, Oromo, or Amharic. 

   Natural language የምንለው everyday ከሰዎች ጋር communicate ለማድረግ የምንጠቀመው language ነው.

2. Programming Languages 💻: These are formal languages designed to instruct computers. They can be further classified into three types:

programming language ደሞ ከሰው ጋር ሳይሆን  ከMachine(computer ) ጋር communicate ምናደረግበት language ነው።

   A. Low-Level or Machine Language ⚙️: This is the most basic type of programming language, consisting solely of binary code (0s and 1s) that is directly understandable by computers. 
   Example: 101001 
   Machine or Low level የምንለው የ0 እና 1 ስብስብ ነው። Computer ቀጥታ understand ሚይደርገው low levelን ብቻ ነው.

   B. Assembly Language 🛠️: This is a mnemonic representation of machine language, making it slightly more understandable to humans. However, it still requires translation into machine language using an assembler. 

   Example: MOV AX, 12H; 

   Assembly ትንሽም ቢሆን በHuman understandable ነው። ግን computer ልክ እንደ low level directly understand ማደረግ አይችልም ስለዚህ Assemblerን ይጠቀማል።

Assembler source codun ወደ machine language translate ያደርገዋል ።

   C. High-Level Programming Languages 🚀: These languages are designed to be easy for humans to read and write. They need to be translated into machine language before execution, which is done using either a compiler or an interpreter:

   • Compiler: A compiler translates the entire source code into machine code before execution.

   • Interpreter: An interpreter translates and executes the code line by line.
  
   Examples: Java ☕, JavaScript 🌐, Python 🐍, C++ ➕➕

⚡Compilation vs. interpretation⚡
Computer programming የአንድ programming language elements  የሚፈለገውን ውጤት እንዲያመጡ በቅደም ተከተል የማቀናበር ተግባር ነው። The effect could be different in every specific case - it's up to the programmer's imagination, knowledge and experience.

ይህ composition ደግሞ ትክክል መሆን አለበት in many senses:

#alphabetically - አንድ program ግልፅ በሆኑ ፊደላት መፃፍ አለበት።

#lexically - እያንዳንዱ programming language የራሱ dictionary አለው; ይህ ደግሞ ከnatural language dictionary በብዙ ቀለል ያለ ነው።

#syntactically - እያንዳንዱ ቋንቋ የራሱ ይሆነ ህግ አለው እናም they must be obeyed for communication to occur

#semantically - the program has to make sense
ነገር ግን program የፃፈው ሰው ሊሳሳት ይችላል የዚያን ጊዜ ደግሞ Each of them can cause the program to become completely useless.

ለምሳሌ አንድ program በትክክል ፅፋችኋል ብለን እናስብ፣  ኮምፒውተራችን ይሄን program execute እንዲያረግልን በምንድ ነው የምናሳነየው?🤔

የፆፍነውን program in to  a machine language render ማረግ ይኖርብናል፣ Luckily, the translation can be done by a computer itself, making the whole process fast and efficient.

High Programming Language ወደ machine language የምንቀይርባቸው ሁለት መንገዶች አሉ:

⚡⚡⚡⚡⚡⚡⚡⚡⚡⚡⚡⚡⚡⚡⚡⚡⚡

#1_COMPILATION - source program አንዴ translated ይሆናል (however, ይህን each time source code በተቀያየረ ቁጥር modify እናረጋለን by getting a file (e.g., an .exe file if the code is intended to run under MS Windows) machine code የያዘ ማለት ነው; then create ያረግነውን file  distribute ማረግ እንችላለን ; ይሄንን translate የሚያረግልን program  compiler ወይም translator ይባላል።

Eg of compiled languages: C, C++, C#

⚡⚡⚡⚡⚡⚡⚡⚡⚡⚡⚡⚡⚡⚡⚡⚡

#2_INTERPRETATION - የአንድ written code ተጠቃሚ ሁሉ source program each time run ማረግ ሲፈልግ translateያረገዋል; ይሄንን የሚያረግልን program ደግሞ interpreter ይባላል፣ አስተርጓሚ እንደማለት ነው። ምክኒያቱ ደግሞ everytime code execute በፈለግን ቁጥር ስለሚተረጉምልን ነው። interprets the code every time it is intended to be executed;

ይህ ማለት ደግሞ source code ልክ እንዳለ distribute ማረግ አንችልም ማለት ነው፣ ምክንያቱም the end user codeኡን execute ለማረግ   አስተርጓሚ(interpreter) ያስፈልገዋል።

Eg of Interpreted languages: Python, JavaScript

Any programming language ከእነዚህ ከሁለቱ መካከል ነው የሚመደበው።

There are very few  languages that can be both compiled and interpreted. usually,  compiled programs run faster than interpreted programs.

Algorithm 🔄

An algorithm is a finite set of well-defined instructions or steps designed to solve a specific problem or perform a particular task. Algorithms can be expressed in various forms, including natural language, pseudocode, and programming languages.



Designing Algorithms 🛠️

Algorithms can be designed using several techniques and tools. One effective tool for designing algorithms is the flowchart 📊.


Flowchart

A flowchart is a graphical representation of the steps involved in a process or algorithm. It uses standardized symbols and arrows to illustrate the flow of control and the sequence of operations. Flowcharts provide a visual way to understand complex processes, making it easier to identify the steps needed to solve a problem.

Common Symbols Used in Flowcharts:

• Oval 🔵: Represents the start and end points of the process.

• Rectangle 🟥: Indicates a process or action step.

• Diamond ♦️: Represents a decision point that requires a yes/no or true/false response.

• Arrow ➡️: Shows the direction of flow from one step to another.

. Parallelogram : Input /output operation
