void testMenu; // postcondition: the test menu is displayed for choose bool isLeapYear(int year); int getcenturyValue(int year) int getYearValue(int year); int getMonthValue(int month, int year); int dayOfweek (int month, int day, int year); YearValue(int year) string dayofweek (int day); // preconditon: day has integer value e, 1, 2, 3, 4, 5, or 6 // postcondition: the name of the day of week is returned as a string. If day has value , then SUNDAY is returned; 1, then MONDAY is returned and so on For any function that the pre-condition and post-condition are missing, the students should add these conditions based their understanding of the function. The main function is given as following
