1. Experimental Description Design a program with some functions of calendar.. 2. Experimental Requirements This calendar software/program should include of the following functions: (1) Output the current date; (2) Output the current year is a leap year or not; (3) Output the specified date is a holiday or not, if it is, printing the holiday name; (4) Output the date of the specified date after n (n>0 and n denotes a integer) days; (5) Output the week No. of the current data in this year. 3: Algorithm Specification Description (pseudo-code preferred) of all the algorithms involved for solving the problem, including specifications of main data structures. 4: Results Table of test cases. Each test case usually consists of a brief description of the purpose of this case, the expected result, the actual behavior of your program, the possible cause of a bug if your program does not function as expected, and the current status ("pass", or "corrected", or "pending"). 5: Discussion and Conclusion Analyze of the founded problems and Comments on further possible improvements. 6: Appendix: Source Code (in C/C++) At least 30% of the lines must be commented. Otherwise the code will NOT be evaluated
