Programming C++ should separate the dates of the 12 constellation in a year?

This can be written in the switch statement. The following is the program I wrote with the if else statement. If the landlord wants to write in the switch statement, first of all, here is the 12 constellation and its corresponding date,/question/157489781.html? si=6。 wtp=wk .

Then any day of the year, such as May 25th, is the first day of the year. I hope the landlord can make statistics. 1, 3, 5, 7, 8, 10 and 12 have 3 1 day, others have 30 days, and February has 28 or 29 days (for simplicity, it is counted as 28 days).

Finally, according to the above data, two points corresponding to each constellation can be found, and an interval is determined by these two points as a constellation. The following is the program I wrote for the landlord, which can be run in VC++6.0 after being saved as *. C. I have sent the specific program code and running results to your qq mailbox, hoping to help you.

# include & ltstdio.h & gt

int table[ 12]={3 1，28，3 1，30，3 1，30，3 1，30，3 1，30，3 1 }； //Number of days corresponding to the month

Int table1[12] = {20,49,79, 108, 139, 17 1 203,234,265. //The division point of the constellation

String str[ 12]=

{"Aquarius", "Pisces", "Aries", "Taurus", "Gemini", "Cancer",

Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn,}; //The name of the constellation
