What is a compiler?
A compiler is a system program that converts instructions written in a high-level programming language into machine code or executable code that a computer can understand and execute. It translates the entire program in one go, producing an output file that can be run independently of the original source code.
Key points:
- Converts high-level programming language instructions to machine language
- Translates the entire program at once
- Generates an output file that can be executed on a computer
How does a compiler work?
When a programmer writes code in a high-level language like C, Java, or Python, the compiler reads the source code and translates it into an intermediate form called object code. This object code is specific to the target platform and can be directly executed by the computer's processor.
Key points:
- Reads the source code written in a high-level language
- Translates the code into object code or machine code
- Object code is platform-specific and can be executed by the computer
Benefits of using a compiler
Using a compiler has several advantages:
- It allows programmers to write code in a more human-readable and structured way.
- It helps catch syntax errors and other mistakes early in the development process.
- It optimizes the code for better performance and efficiency.
- It enables the creation of standalone executable files that can be distributed and run on different machines.
Key points:
- Enables human-readable and structured code
- Helps catch errors early
- Optimizes code for better performance
- Creates standalone executable files for distribution
