People can understand a high-level language. To clarify this, they contain words and phrases from commonly used languages such as English or other languages. Computers, however, cannot understand high-level languages like we humans. The computer can understand only the programs developed in binary systems known as the machine code.
First, a computer program is usually written as a source code in the high-level language. These source codes must be converted to a machine language, and the compilers and interpreters have a role to play. The compiler translates the source code to Machine code and Binary code. The compiler is a translator program that translate source code into the executable program from a high-level programming language to a lower-level language e. In a compiler, the code generator module checks every character of the source text.
It can check Syntax errors. It is the process of analyzing a string of symbols and conforming to the rules of grammar. If something is wrong, it will produces object code and an error message. The Compiler can diagnose grammatical errors only. If no errors are detected, the compiler converts the source code into machine code.
The compiler links the various code files to programs such as exe. The program finally runs. Thus, Python stands in the center of both parameters. September 9, Table Of Contents. What are Compilers? Working of the Compiler What is an Interpreter? Share 0. Tweet 0. Pin it 0. Compiler Interpreter.

The execution of the program takes place after every line is evaluated and hence the error is raised line by line if any. All the errors are shown at the end of the compilation and the program cannot be run until the error is resolved. Displays the errors from line to line. It also reports errors found in the program. The computer further processes the machine codes to perform the specified tasks. What is Interpreter?
An interpreter is a computer program that performs the same functions as the compiler, but instead of converting an entire program at once, the interpreter converts each high-level program statement into machine code one by one.
This includes the source codes of a high-level language, pre-compiled codes as well as scripts. Besides, an interpreter compiles one line of code at a time. Interpreters take the next line of code only when the previous one has compiled. Interpreters, on the other hand, do not generate any intermediate object code that makes it memory resourceful. Whereas, the interpreter displays the errors of each statement one by one, making it easier to detect errors.
Besides, when the interpreter finds an error, it stops the translation and the translation starts from the same position when the error is removed. Whereas in the interpreter, it is a one-step process where the source code is compiled and executed at the same time.
An interpreter takes a single line of code at a time. The compiler generates an intermediate machine code. The interpreter never produces any intermediate machine code. The compiler produces an output program. The interpreter does not produce any output program.
