Write a function that determines the maximum and minimum values from a one-dimensional array. assume that the corresponding function prototype statement is void ranges(int x[], int npts, int *max_ptr, int *min_ptr) where npts contain the number of values in array x, and max_ptr and min_ptr are pointers to the variables in which to store the maximum and minimum values in the array.

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.
