Days between Two Dates (the Best Method!!!)

/* Write a program to calculate the difference between two dates in number of days.
 * The dates are entered at two consecutive lines in format day-month-year.
 * Days are in range [1…31]. Months are in range [1…12].
 * Years are in range [1900…2100]. */
