What are the roles of linkers and libraries?
The job of the linker is three fold: First, to take all the object files generated by the compiler and combine them into a single executable program. Second, in addition to being able to link object files, the linker also is capable of linking library files.
What is shared library linking?
A shared library is a file containing object code that several a. out files may use simultaneously while executing. When a program is link edited with a shared library, the library code that defines the program’s external references is not copied into the program’s object file. Instead, a special section called .
What does a linker file do?
In computer science, a linker is a computer program that takes one or more object files generated by a compiler and combines them into one, executable program. The linker combines these separate files into a single, unified program, resolving the symbolic references as it goes along.

How are linkers used during the compilation process?
Linking is the final step of compilation. The linker merges all the object code from multiple modules into a single one. If we are using a function from libraries, linker will link our code with that library function code. In static linking, the linker makes a copy of all used library functions to the executable file.
What is in shared library?
Shared libraries are libraries that are loaded by programs when they start. When a shared library is installed properly, all programs that start afterwards automatically use the new shared library. override specific libraries or even specific functions in a library when executing a particular program.
