Hi ya'll I was wondering if someone was able to help me with Zeller's formula, I am trying to write a program to find the day of the week using his formula. I need to write a program that takes a date from the user and uses Zeller's Formula to determine the day of the week. I am to use a switch statement to convert the final day of week number given by zeller's into a day of the week string for output. Will someone please help me, and I need to use functions to make my program more readable. This is what I have, but it just is too complicated, I was wondering if someone could help me out a little bit, clean it up and make it actually work where I get the correct day? Please help I am appreciative of any help that can help me!
Code:#include <iostream> #include <iomanip> #include <string> using namespace std; string DayoftheWeek(int , int , int ); int main() { int mon, day, year; char YorN; string WeekDay; { cout << "Enter the number of the month:"; cin >> mon; //month of year cout << "Enter day of the month:"; cin >> day; //day of month cout << "Enter the year:"; cin >> year; //year number cout << "The day of the week for the date you have entered is: "; WeekDay = DayoftheWeek(mon,day,year); //function call cout << WeekDay; cout << ".\n"; cout << "\n\n\nEnter Y to try another, N to stop.\n\t\t"; cin >> YorN; } while(YorN=='Y'||YorN=='y'); return 0; } string DayoftheWeek(int a,int b, int year) //To find the day of week. { string WeekDay; int c,d,w,x,y,z,r; c = year % 100; d = year / 100; if(a <= 2) { a += 10; } else { a -= 2; } { w = (13 * a - 1) / a; x = c / 4; y = d / 4; z = w + x + y + b + c - 2 * d; r = z % 7; } switch(r) { case 0: WeekDay = "Sunday"; break; case 1: WeekDay = "Monday"; break; case 2: WeekDay = "Tuesday"; break; case 3: WeekDay = "Wednesday"; break; case 4: WeekDay = "Thursday"; break; case 5: WeekDay = "Friday"; break; case 6: WeekDay = "Saturday"; break; } return WeekDay; }
