1. (8 pts.) Download the source code file (mystery.c). Open the file using a text/programming editor, review the code, assign your student ID number to the student_id variable as indicated in the comments, compile and run the program. (a) Submit all the output produced by the program in a text file. Take note of the printed value of "xx", to be used in Problem 3. (b) Explain what is the purpose of the code in the "mystery block" or, in other words, what is the value calculated in i2
