What is a Compiler
A compiler is a special software program that translates the code written by a programmer in a high-level language (like Java, C, or Python) into machine language (0s and 1s). This machine code is what the computer’s processor can actually understand and execute.
In short, the compiler works like a translator between humans and computers. The process of changing high-level code into machine code is called compilation.
Advantages of Compiler
- Compiled code runs faster in comparison to Interpreted code.
- Compilers help improve the security of Applications.
- Compilers give Debugging tools, which help in fixing errors asily.
Disadvantages of Compiler
- The compiler can catch only syntax errors and some semantic errors
- Compilation can take more time in the case of bulky code.
What is interpreter
An interpreter is a program that runs code directly. Instead of converting the entire program into machine code at once (like a compiler does), an interpreter reads the program line by line, translates it, and executes it immediately.
This makes it easier to test and debug programs, but usually a bit slower compared to compiled code.
Advantages of Interpreter
- Programs written in an Interpreted language are easier to debug.
- Interpreters allow the management of memory automatically, which reduces memory error risks.
- Interpreted Language is more flexible than a Compiled language
Disadvantages of Interpreter
- The interpreter can run only the corresponding Interpreted program.
- Interpreted code runs slower in comparison to Compiled code
Main Difference
Compiler = Translate all at once → then run.
Interpreter = Translate and run → line by line.
