Hello friends,

Why is linking necessary in a program?

[PrimeItSolution]

Linking refers to the creation of a single executable file from multiple object files. ... Instead, using so called "conditional compilation", it is necessary to compile only those source files that have changed; for the rest, the object files are sufficient input for the linker.

Hi Friends,
Linking is the process of collecting and combining various pieces of code and data into a single file that can be loaded (copied) into memory and executed. Linking is usually handled quietly by the linker, and is not an important issue for students who are building small programs in introductory programming classes.it is necessary to compile only those source files that have changed; for the rest, the object files are sufficient input for the linker.
