Question

I should check if month is 1 through 12,day is 1 through daysOfMonth[month], or day is 1 throughdaysOfMonth [month]+1 if year is a leap year (use function 5.below) and year is 1000 through 9999, return –1 in a returnstatement if NOT. Then calculate the Day-of-year date given theCalendar date USING THE ARRAY OF DAYS PER MONTH. Remember to add 1to the Day-of-year date if the date is after Feb. 28 and the yearis a leap year (leap year function specs below – see 5.below). Return the Day-of-year date in a returnstatement. This is what I have so far but I keepgetting the wrong answer: int convertDateToDayOfYear ( intdaysOfMonth [], int month, int day, int year )
{
int i;
int sum;
int dayOfYear;

if( month >= 1 && month <= 12 && day >= 1&& day <= daysOfMonth [month] && year > 1000&& year < 9999 )
if( determineLeapYear ( year ) == 1 && month > 2 || day> 28 )
for( i=0, sum=0; i < month; i++ )
{
sum += daysOfMonth [i];
dayOfYear = sum + day + 1;
}
else
for( i=0, sum=0; i < month; i++ )
{
sum += daysOfMonth [i];
dayOfYear = sum + day;
}
else
return -1;
return dayOfYear;
}

int determineLeapYear ( int year )
{
if( (year % 4 == 0 && year % 100 != 0) || year % 400 == 0)
return 1; /* a leap yaer */
else
return 0; /* not a leap year */

Explanation / Answer

please rate - thanks #include #include int convertDateToDayOfYear ( int daysOfMonth [], int month, intday, int year ); int determineLeapYear ( int year ); int main() {int month,day,year,doy; int daysOfMonth[12]={31,28,31,30,31,30,31,31,30,31,30,31}; FILE *file;              file =fopen("input.txt","r");         if(file == NULL)         {                printf("Error opening file! ");                return 0;         } while(fscanf(file,"%d",&month)>0) {fscanf(file,"%d",&day); fscanf(file,"%d",&year); doy=convertDateToDayOfYear (daysOfMonth, month,day,year ); if(doy==-1) printf("%d/%d/%d invalid date "); else    printf("%d/%d/%d is day %d of theyear ",month,day,year,doy); } fclose(file); getch(); return 0; } int convertDateToDayOfYear ( int daysOfMonth [], int month, intday, int year ) { int i; int sum; int dayOfYear; int leap=determineLeapYear ( year ); if( month >= 1 && month = 1&& day 1000 && year < 9999 ) {    for( i=0, sum=0; i
