What is input and output of compiler?

What is input and output of compiler?

Input and output The input to a compiler is a file (or files) containing a program in a source language. The output of a compiler is a different file containing code in a target language, often a low-level machine language, though it could just as well be another high-level language.

What do you call the output that the compiler produces?

A compiler takes the program code (source code) and converts the source code to a machine language module (called an object file). Another specialized program, called a linker, combines this object file with other previously compiled object files (in particular run-time modules) to create an executable file.

What can the output of a compiler be used for?

The name “compiler” is primarily used for programs that translate source code from a high-level programming language to a lower level language (e.g. assembly language, object code, or machine code) to create an executable program.

What is a compiler in computer?

compiler, computer software that translates (compiles) source code written in a high-level language (e.g., C++) into a set of machine-language instructions that can be understood by a digital computer’s CPU. Compilers are very large programs, with error-checking and other abilities.

What will be the output of the program?

What will be the output of the program if value 25 given to scanf()? The scanf function returns the number of input is given. printf(“%d\n”, scanf(“%d”, &i)); The scanf function returns the value 1(one). Therefore, the output of the program is ‘1’.

What is a out in C?

out is a file format used in older versions of Unix-like computer operating systems for executables, object code, and, in later systems, shared libraries. The term was subsequently applied to the format of the resulting file to contrast with other formats for object code.

What is the output from the linker process?

Linker are also called link editors. Linking is process of collecting and maintaining piece of code and data into a single file. Linker also link a particular module into system library. It takes object modules from assembler as input and forms an executable file as output for loader.

What is a computer compiler?

What is compiler example?

1. Compiler : The language processor that reads the complete source program written in high-level language as a whole in one go and translates it into an equivalent program in machine language is called a Compiler. Example: C, C++, C#, Java.
