Coding word has came from the word "Code" and Programming word has came from the word "Program" meanwhile coding and programming both are same except the literal meaning. When we writing codes then it is said to be Coding and when we making a program through codes then it is said to be Programming.
Program is sets of codes that does particular task. Programs are made through codes that can do the tasks according to the codes such as we can write codes that gives us a multiplication table of any number then this is called a Program that gives us a multiplication table of a number.
How Coding Works ?
Now let's take a deep look how actually coding works, how we command computers to do particular task through our codes and how they do task. Let's dive in it and know!
Binary Numbers - are the only thing that computer understands, computer neither understands any other number, any sign nor any english letter or any character. binary numbers are 0 and 1 number through which computers works and performs various tasks.
Then how to communicate with computer if it understands only binary numbers?
Binary numbers are complicated numbers that human brain can't understand easily. For example if we want to write a word "Hi" in binary numbers then we will have to write "01001000 01101001" now just like that if we have to command computer to do any task like "print(Hi)" then we will have to convert each character of "print(Hi)" in binary number and give it to the computer so that computer can understand it and print "Hi".
But is it easy? Absolutely Not! we will have to write millions of numbers according to tasks that we want to command the computer to do which is absolutely hard.
Then what's the solution of it? This is where Programming Languages helps.
What Are Programming Languages ?
Programming Languages - are computer languages used to communicate to a computer. They provide a structured way to write code that computers can understand, execute and perform tasks. Different programming languages have different syntax and semantics.
How Programming Languages Solved The Issue Of Binary Numbers - Basically instead of writing thousands of binary numbers in order to communicate with computer, we use programming languages to communicate with computer as with the help of programming language we type the codes in english letters that we can easily understand so we don't have to worry about binary numbers anymore.
But if computer doesn't understands english characters as well then how computer is going to understand english codes written through programming languages?
For this problem we have Interpreter/Compiler.
Interpreter/Compiler
Interpreter/Compiler - both does a same task but works in different way. Interpreter/Compiler directly executes instructions written in a programming language without the need for prior conversion. They translates code into computer/machine language/code and executes it immediately.
Basically Interpreter/compiler converts each of our code character by character into binary numbers and give it to the computer so that computer understands it and then performs the task that we commanded it to do through our codes.
Interpreter - executes the codes line by line and executes it immediately. Interpreters are often used in scripting languages like Python or JavaScript.
Compiler - A compiler, on the other hand, translates entire programs written in a programming language into machine code or another language before execution. This process typically involves several steps: lexical analysis (breaking code into tokens), syntax analysis (checking for correct syntax), semantic analysis (ensuring logical correctness), and code generation (producing machine-readable code). Compiled languages include C, C++, and Java.
In summary :-
Interpreter: Executes code line by line, translating and executing on the fly.
Compiler: Translates entire programs into machine code or another form before execution.
Uses Of Coding/Programming Languages
Coding - is vastly used in all around the world in all aspects. Coding is used usually in every electronic devices from TV remote to the TV. From hardware to software, coding is used everywhere.
• Coding is utilized in various fields and environments, including web and software development, where it is essential for creating websites, applications, and software systems.
• In the realm of data science and artificial intelligence, coding enables the analysis of large data sets and the creation of intelligent models.
• The gaming industry relies heavily on coding for developing interactive video games, while embedded systems and IoT devices in smart homes, healthcare, and automotive industries are programmed using code.
• Financial technology (FinTech) uses coding to develop online banking systems and cryptocurrency platforms.
• Many machines and robotics are totally relied on coding in order to function.
• Additionally, coding is pivotal in cybersecurity to safeguard digital information, in educational technology for developing e-learning tools, and in mobile app development for creating applications on smartphones and tablets.
• Different Programming Languages are used in different aspects and in same aspects as well in some of the cases.
See the above image to get a basic idea what programming languages are used to do what specific tasks.
How To Start Coding ?
How To Start Coding - After knowing all about coding, it's time to see how to start coding.
To start coding you need to first understand what is coding, how it works, what are it's uses and you have already understand these things so how you can start coding now?
To enter the field of coding you have to start with learning a programming language that makes you understand what actually you have to do coding, how you have to write codes, how codes and programs works and so on that you will be learnt by yourself gradually during the time of learning a programming language.
So with which language you should start?
In my and in most of the people's opinion, one should start with Python Programming Language as it's best for beginners to understand various stuffs. Python has easy and decent syntax that one can understand easily so if you are a beginner and you are going to learn your first language then you should start with Python.
You can start with other langugages as well like C, C++ or Java but these languages are bit harder than Python so you can choose accordingly with what you want to start.
After learning any programming language now you have a good idea of how coding and all works so now you have to choose in what field you want to get into, either App Development, Web developmetn, Hacking or something else.
After choosing a field you just have to learn stuffs according to your field and All Set!
Conclusion - Now you are completely ready to dive into the field of programming as hopefully now you understand all the important things you need to know about coding such as what is coding, how coding works, uses of coding, what are programming languages and uses of it, what is interpreter and compiler and at the end How to start coding.
