Which functions in PERL allows you to include a module file. State their differences.

The functions that allow us to include a module file or a module is the “use” and “require” function. The differences between the two are:

1. The “use” function is used for loading the module at the compile time whereas the “require” function is used for loading the module at the runtime.
2. “Use” calls the import function of modules inbuilt whereas “require” calls the import module separately.
3. The “use” function is used only for the modules and that too for including .pm type file. The “require” function is used for both the libraries and modules.
4. In “use,” we are not required to specify the file extension whereas in “require,” it is mandatory to specify the file extension.
