/* Day of Week Calculator This is a Smart and Brief approach to get the Day of the Week from a Date given by the user... It uses an algorithm to calculate odd days in terms of 0-6 and Prints the respective Day... 0=Sun, 1=Mon, 2=Tue and so On... This is a non updated version and thus does not have the code in a function. If any one needs it, its here: -> int day_of_week(int day,int month, int year) { int lpyr,yr,ody,odm=0,odd,flag=0,ods; int mnth[12]={31,28,31,30,31,30,31,31,30,31,30,31}; if(year<100) { if(year%4==0) flag=1; } else { if(year%400==0) flag=1; else if(year%100==0) flag=0; else if(year%4==0) flag=1; } if(flag==1) mnth[1]=29; lpyr=(year-1)/4; yr=year-1-lpyr; ody=(lpyr*366)+(yr*365); for(int i=1;i using namespace std; int main(void) { cout<<"Day of Week Calculator"<>day>>month>>year; //This Part Calculates if the Year is Leap or Not, and if it is, the Days of February in the Month Array are changed to 29... if(year<100) { if(year%4==0) flag=1; } else { if(year%400==0) flag=1; else if(year%100==0) flag=0; else if(year%4==0) flag=1; } //Day Determining Part - Uses Odd Day method to Calculate the Day... if(flag==1) mnth[1]=29; lpyr=(year-1)/4; yr=year-1-lpyr; ody=(lpyr*366)+(yr*365); for(int i=1;i
