1. Difference between Compiler and Interpreter

Here are some additional differences between a compiler and an interpreter:

1. Intermediate Code:

Compiler: Converts the source code into an intermediate object code or machine code before execution. The object code is independent of the source code and can be executed on any machine that supports the compiled code format.

Interpreter: No intermediate code is generated. It directly interprets the source code line-by-line each time the program is run.

2. Error Handling:

Compiler: Displays all errors in the source code after the entire code is compiled. The programmer has to fix these errors and then recompile the program.

Interpreter: Stops at the first error it encounters and reports it. The programmer can then fix the error and resume execution from where it left off.

3. Memory Usage:

Compiler: Requires more memory for storing the intermediate object code or executable file. Once compiled, the machine code is independent of the original source code.

Interpreter: Uses less memory since no object code or executable is created, but it needs to load the source code and interpret it during every execution.

4. Execution Speed:

Compiler: Faster execution since the program is fully translated into machine code before it runs.

Interpreter: Slower, as translation happens on the fly, and the program is executed line-by-line each time it runs.

5. Portability:

Compiler: Compiled machine code is often platform-specific. The code may need to be recompiled for different systems.

Interpreter: The interpreted program can run on any system that has the appropriate interpreter installed, making it more portable in certain cases.

6. Re-usability:

Compiler: Once a program is compiled, the compiled code can be reused without recompiling, as long as no changes are made to the source code.
