Interpreter

Interpreters are a type of translator that converts a program line-by-line to machine language while executing it. They perform the following steps:

• Reads and analyzes the source code: The interpreter reads the source code line-by-line and analyzes it to understand the syntax and structure of the program.


• Translates code to machine language: As each line of code is read, the interpreter converts it to machine language or bytecode, which can be directly executed by the computer.


• Executes the code: After translating a line of code, the interpreter immediately executes it. This allows for real-time feedback and instant execution of the program.


• Handles errors: If the interpreter encounters an error in the code, it immediately stops the execution and provides an error message. This allows for quick identification and resolution of issues.


• Slower execution: Interpreted programs tend to be slower than compiled programs because the conversion of each line to machine language happens during runtime.

Examples of interpreted programming languages include Python, JavaScript, and Ruby.
