Question-According to the Gregorian calendar, it was Monday on the date 01/01/1900. If any year is input through the keyboard write a program to find out what is the day on 1st January of this year.
Solution-
it's nothing but a simple program, it can be easily done by using above concept. that's how it goes.
#include<stdio.h>
int main()
{
int yr=2012,totdays,normaldays,leapdays,k=yr-1;
printf("Enter any year\n");
scanf("%d",&yr);
normaldays=365*k;
leapdays=k/4+k/400-k/100;
totdays=normaldays+leapdays;
if(totdays%7==0)
printf("Monday\n");
if(totdays%7==1)
printf("Tuesday\n");
if(totdays%7==2)
printf("Wednesday\n");
if(totdays%7==3)
printf("Thursday\n");
if(totdays%7==4)
printf("Friday\n");
if(totdays%7==5)
printf("Saturday\n");
if(totdays%7==6)
printf("Beloved Sunday");
return 0;
}
