So, if you make a mistake, you need to make changes in the syntax of your program. Otherwise, it will not compile. An interpreter is a computer program, which coverts each high-level program statement into the machine code. This includes source code, pre-compiled code, and scripts.
Both compiler and interpreters do the same job which is converting higher level programming language to machine code. However, a compiler will convert the code into machine code create an exe before program run.
Interpreters convert code into machine code when the program is run. It makes programming process easy. However, it must be translated into machine language before execution.
This translation process is either conducted by either a compiler or an interpreter. Also known as source code. Machine languages are very close to the hardware. Every computer has its machine language. A machine language programs are made up of series of binary pattern. Machine language programs are executable so that they can be run directly. To make code portable, the source code is first converted to Object Code.
It is an intermediary code similar to machine code that no processor will understand. At run time, the object code is converted to the machine code of the underlying platform.
To exploit relative advantages of compilers are interpreters some programming languages like Java are both compiled and interpreted. The Java code itself is compiled into Object Code. Always executes conditional control statements like if-else and logical constructs faster than interpreter.
Because the entire object code has to reside in memory, compiler programs take more memory than interpreter. Interpreter programs are more memory efficient because they do not generate intermediate object code.
Error is reported as soon as the first error is occurred and did not work further until the error is not fixed. Because it reports error as quickly and stops working so that debugging is easy as compared to compiler.
Runs the program from the first line and stops execution until it encounters an error. Less efficient languages but easy to debug which makes an ideal situation and choice for new students. To make changes, we have to change the source code. The interpreter uses the source code every time and works line by line; Therefore, we can easily make changes.
The compiler displays all errors after compilation, which complicates the error detection and removal process. The interpreter displays the errors of each line one by one, if any, making it easier to detect and remove errors. The compiler is best suited for the production environment. An interpreter is best suited for a software development environment.
Summary Compiler and Interpreter both are intended to convert the source codes into machine codes, but there are differences in their working and operating procedure. While compilers take source code at once, interpreters take parts of the source code that is, statement by statement during the conversion. Difference Between Compiler and Interpreter. Both Compilers and Interpreters are programs that convert high-level language source codes into machine language machine codes to make it understandable by the computers.
Before discussing the difference between compiler and interpreter, let's have a quick overview of both:. Compiler and Interpreter both are intended to convert the source codes into machine codes, but there are differences in their working and operating procedure.
