What happens when you write a code?
when you write code its stored as text. then depending on what language you are using such text is compiled (as in C, C++). or Interpreted (phyton, visual basic, javascript). when compiled you end up having a lot of data that can run a lot easier on a computer.
What does a computer do with code?
Almost all programming languages work the same way: You write code to tell it what to do: print(“Hello, world”). The code is compiled, which turns it into machine code the computer can understand. The computer executes the code, and writes Hello, world back to us.
What is writing code for computers?
“Writing code,” “coding,” and “programming” are basically interchangeable terms. Broadly speaking, knowing how to write code is the process of creating instructions that tell a computer what to do, and how to do it. Codes are written in various languages, such as javascript, C#, Python, and much more.
What happens when you write a code and compile it?
A compiler takes the program code (source code) and converts the source code to a machine language module (called an object file). Another specialized program, called a linker, combines this object file with other previously compiled object files (in particular run-time modules) to create an executable file.
What does Java use for execution?
In Java, programs are not compiled into executable files; they are compiled into bytecode (as discussed earlier), which the JVM (Java Virtual Machine) then executes at runtime. Java source code is compiled into bytecode when we use the javac compiler. The bytecode gets saved on the disk with the file extension .
Does writing code tell the computer what to do?
The short answer is that writing code tells the computer what to do, but it’s not quite that simple. So here’s the longer answer. A computer can only understand two distinct types of data: on and off. In fact, a computer is really just a collection of on/off switches (transistors).
What is coding and how does it work?
What is coding? Coding is a skill where you take instructions (the steps in a task) and translate it into a language the computer understands since computers do not communicate like humans. They communicate in a language called BINARY and it is uses 0’s and 1’s. Coders write the instructions using a programming language.
What are programming languages and how do they work?
Thousands of different programming languages make it possible for us to create computer software, apps and websites. Instead of writing binary code, they let us write code that is (relatively) easy for us to write, read and understand. Each language comes with a special program that takes care of translating what we write into binary code.
How do you write a computer program?
To be able to write a computer program by typing out billions of 1s and 0s would require superhuman brainpower, and even then it would probably take you a lifetime or two to write. This is where programming languages come in… Here’s a simple example of some code: print ‘Hello, world!’ That line of code is written in the Python programming language.
