Explain the Working of Linker?

Linker as well called as link editor and binder. A linker is the program that combines object modules to form an executable program. Several programming languages allow you to write different pieces of code called modules separately. This simplifies the programming task for the reason that you can break a large program into small, more manageable pieces. Ultimately, though, you need to put all the modules together this is the job of the linker.

In addition to combining modules a linker as well replaces symbolic addresses with real addresses. Consequently you may need to link a program even if it contains only one module.
