COMPILERS INTERPRETERS AND ASSEMBLERS PDF

Assembler, Compilers and Interpreters. As stated earlier, any program that is not written in machine language has to be translated in machine language before it. An Assembler takes programs written in the Assembly Language and made life easier and paved the way for the Compilers & Interpreters. Give Examples Compiler: Compilers are used to convert high level Assembers : Assembler are used to convert assembly language code into machine code.

The main difference between compiler interpreter and assembler is that c ompiler converts the whole high level language program to machine language at a time while interpreter converts high level language program to machine language line by line and assembler converts assembly language program to machine language.

In addition to high level languages and machine language, there is another language called the assembly language. Compiler, interpreter and assembler are translators that convert high level or assembly language based programs to machine language.

The function of the memory is to store information. Bytecode assemmblers code which is compiled and can then be interpreted. Hence there is a one-to-many correspondence between the high-level language instructions of a source program, and the machine asemblers instructions of its equivalent object program.

To generate error messages, if there are errors in the program. The basic purpose of interpreter is same as that of complier. It is not possible to execute the program without fixing those errors. Discuss machine language and give its advantages and disadvantages.

Thus the job of a complier includes the following: Compiler A compiler translates the whole program into machine code before the program is run. Because the source program is translated fresh every time it is used, it is slow process or execution takes more time.

Unlike compilers, interpreters convert the source code to machine code line by line. Translators are assemblersinterpreters or compilers. Therefore, the high level or assembly program should be converted into machine language for the computer to understand the instructions. Home Basic Computer Engineering Compare compilers, interpreters and assemblers. A compiler is a program that translates a programme written in HLL to executable machine language.

It can be difficult to test individual lines of compiled code compared to interpreted languages as all bugs are reported after the program has been compiled.
