Hi guys im having a slight problem passing the month and year variable to a function that i have created called int totalDays(unsigned year, unsigned month) now when i do a print inside the function it prints 0. Even though i have inputted using a key for example 6 for the month and 2006 for the year.
So pretty much after i have entered the input for month and year it does not carry the value that i have entered into the totalDays function instead its always 0 why is that?
sorry for posting the whole thing but its got something to do with how im passing variables through the function impretty sure.
int main(void)
{
unsigned month;
unsigned year;
int i;
int daysOfMonth[] = {31,28,31,30,31,30,31,31,30,31,30,31};
month = getMonth();
year = getYear();
displayCalendar(month, year);
/* function call : if its a leap year february is now 29 days instead of 28*/
if(isLeapYear(year))
{
daysOfMonth[1] = 29; /* change feb to 29 days*/
}
return EXIT_SUCCESS;
}
