What is the role of the Compiler in a C program?

Answer 1

The compiler takes the file that you have written and produces another file from it. In the case of Pascal programs, for instance, you might write a program called myProg.pas and the Pascal compiler would translate it into the file myProg.exe which you could then run. If you tried to examine the contents of myProg.exe using, say, a text editor, then it would just appear as gobbledy-gook.The compiler has another task apart from translating your program. It also checks it to make sure that it is grammatically correct. Only when it is sure that there are no grammatical errors does it do the translation. Any errors that the compiler detects are called compile-time errors or syntax errors. If it finds so much as one syntax error, it stops compiling and reports the error to you.While the above is true, more simply put, a compiler translates source code to a language the computer understands. A computer does not operate in the language used for source code programming. Basic C code is based on discrete mathematics. The computer operates on what is called Assembly Language or Machine Code, which a computer understands, and contains the specific instructions for the computer to perform the source code's design.

Answer 2

A compiler, in computer programming, is a program that may or may not be written in the language the compiler is written for that takes a program written in the language that the compiler is designed for and spits out another file. In Java, this file is a collection of "bytecodes", or a program for the JVM(Java Virtual Machine). This is the same in C, but the program is turned into an executable file. Other languages in which the compiler spits out an executable file are FORTRAN, COBOL, C++, and many others.

Answer 3

C is a compiled programming language. You can not run your program using the source code file.

Compiler does the binary code from source files.

First, it runs the preprocessor, which removes comments and processing directives that begin with `# '.

Then, the compiler converts the program text into an object file. At this stage, the compiler optimizes a program, that it takes up less space, or to work faster (depending on compiler settings).

Then, it runs the linker, which assembles the executable file from object files (files).

C has many compilers for various platforms.

PS I'm sorry if there are grammatical errors, I'm not a native speaker.

Answer 4

Strangely enough we use a C compiler. However, C has evolved through several standards over the years so it is important you use the latest standard when writing code and use the appropriate standards-compliant compiler to compile that code. Moreover, compilers are platform-dependent and each platform has several implementations, so it is important to avoid compiler-dependencies if you want to ensure code is portable.

Answer 5

Translates from source program (*.c) to object code (*.obj or *.o).

Answer 6

Nothing. Compiler is not a part of the program, it is a separate program that translates from source to object code (or Assembly).
