What Is Source Code And Object Code?

What does compiled code look like?

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..

3. Object code. Object code is code generated by a compiler or other translator, consisting of machine code, byte code, or possibly both, combined with additional metadata that will enable a linker, loader, or linker-loader to assemble it with other object code modules into executable machine code or byte code.
