Create a library. The library should contain two functions, Hello() and World(). Calling the Hello() function should print out the string "Hello"; calling the World() function should print out the string "World." [7 points] a) Write a simple program that uses the library (testing the use of the library). b) Create your own makefile that tests for the correct working of the functions. It should define two dependency/command blocks as: First block should give the dependencies for the object code file of the simple program that uses the library, as well as the command to compile the source code file into the object code file. Second block should define the use of the linking stage command. Therefore, the executable file of your program, its object code file (.o) and library file (.a) would be the dependencies part of this block.
