2.3 Observeandcomparewiththeoutputsofthefunctionsandthe macros. Do the functions and macros generate the same results? Submit your short answer and the screenshots of the test run and label the file hw02q2.pdf [2 points]

Programming Portion:

3. You are given a file named hw02q3.c. All instructions are given in the form of comments in the file. You are to again run the file in both Visual Studio and in GCC and observe the outputs and make changes as requested. Please read all instructions very carefully, then complete and submit the updated file as hw02q3.c. [25 points]
