Programmer facts for kids
A computer programmer is someone who writes instructions for computers. These instructions are called computer programs. You might also hear them called software developers or coders. Programmers use special languages, like programming languages, to talk to computers.
Their main jobs include writing the program's source code (the instructions), testing if it works correctly, and fixing any problems. Fixing problems is called "debugging." Programmers often use special tools like text editors and IDEs (Integrated Development Environments) to help them write and test their code.
Programming is a cool job because many programmers can work from almost anywhere in the world. This is called telecommuting. It means they can do their work using the Internet instead of going to a traditional office every day.
Some programmers become famous because their software is used by millions of people. For example, Linus Torvalds created a very important part of the Linux operating system, which powers many computers and devices around the world.

What is a Computer Programmer?
A computer programmer is like a translator between humans and computers. They take ideas for what a computer should do and turn them into step-by-step instructions that the computer can understand and follow. These instructions form a "program."
Computers only understand very specific commands. Programmers learn different programming languages, like Python, Java, or C++, to write these commands. Each language has its own rules, like human languages have grammar.
What Do Programmers Do?
Programmers have several key tasks they do every day:
- Writing Code: This is the main part. Programmers write the actual instructions, line by line, using a programming language. This code tells the computer exactly what to do, from showing a picture to running a complex game.
- Testing Programs: After writing code, programmers test it to make sure it works as expected. They try different things to see if the program crashes or gives wrong answers.
- Debugging: If a program doesn't work right, it has "bugs." Debugging means finding and fixing these errors. It's like being a detective, looking for clues in the code to solve the problem.
- Maintaining Software: Programs often need updates or changes over time. Programmers help keep software working well, adding new features or fixing issues that appear later.
Programmers use special software tools to help them. A text editor is like a fancy notepad for writing code. An IDE is an all-in-one tool that helps them write, test, and debug their programs more easily.
Where Do Programmers Work?
Programmers work in many different places and industries. They can be found in technology companies, banks, hospitals, schools, and even game studios. Almost every business today uses computers, so programmers are needed everywhere.
Many programmers work in offices, often in teams, collaborating on big projects. However, a growing number of programmers work from home or from anywhere with an internet connection. This flexibility is a big part of why many people enjoy this career.
Famous Programmers
Throughout history, many people have contributed to the world of programming.
- Ada Lovelace: Often considered the first computer programmer. In the 1800s, she wrote notes about Charles Babbage's Analytical Engine, describing how it could go beyond just calculations to create music or art.
- Grace Hopper: A brilliant computer scientist and U.S. Navy admiral. She helped create one of the first programming languages, COBOL, and popularized the term "debugging" after finding a moth in a computer!
- Bill Gates: Co-founder of Microsoft, he helped create the MS-DOS operating system and Windows, which became widely used around the world.
- Steve Wozniak: Co-founder of Apple Inc., he designed the Apple I and Apple II computers, which helped kickstart the personal computer revolution.
- Linus Torvalds: The creator of the Linux kernel, a core part of the Linux operating system. Linux is used in many servers, smartphones (like Android), and other devices.
Programming Languages
Just like people speak different languages, computers can understand many different programming languages. Each language has its strengths. Some are great for building websites, others for making games, and some for creating mobile apps.
A classic example used to show how different languages work is the "Hello world program." This is a very simple program that just makes the computer display the words "Hello, World!" Even for this simple task, the code looks very different depending on the programming language used.
