Why is linking necessary in a program?
 

Hello friends,

Why is linking necessary in a program?

Linking is necessary just like your tons of singature links below because you believe it will rank on search engine but in reality it doesn't.

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.
