Write a function named days() that determines the number of days since January 1, 1900 for any data passed as a structure. Use the Date structure: struct Date { int month; int day; int year; }; In writing the days() function, use the convention that all years have 360 days and each month consists of 30 days. The function should return the number of days for any Date structure passed to it. Write a main() function to test your function.
