When asked to recall the date of john kennedy’s assassination, peter draws a blank; however, when asked whether it was october 24, 1962, november 22, 1963, or february 1, 1965, he correctly answers with the second of the choices. this example most clearly demonstrates the value of
a. state-dependent memory
b. retrieval cues
c. cross links in deep structure
d. mnemonic devices

Write a program that prints the day number of the year, given the date in the form month-day-year. for example, if the input is 1-1-2006, the day number is 1; if the input is 12-25-2006, the day number is 359. the program should check for a leap year. a year is a leap year if it is divisible by 4, but not divisible by 100. for example, 1992 and 2008 are divisible by 4, but not by 100. a year that is divisible by 100 is a leap year if it is also divisible by 400. for example, 1600 and 2000 are divisible by 400. however, 1800 is not a leap year because 1800 is not divisible by 400.
