Days since 1/1/1800,that day was Wednesday. Need to convert a date in the form mo/dy/year into this single number. Need a function to print out the day of the week, and a function to print out the date in the form month day, year where the month is completely spelled out. Need to write a program that uses this class to read data from a file and print the data in a new format on the standard output device. **Having trouble converting a date in the form mo/dy/year ino the single number.** The code I'm stuck on is in bold bellow, thanks in advance.
