date validation

[swapnali143]

hey friends can you give some example to validate date accepted by user in variable
as follows
int day;
int month;
int year;
It must validate entered details are correct or not ans
It must check that date is more than System date or not

Just write a date validation function. It would take 3 arguments and return true or false of the 3 arguments are a valid date or not.

Then write a date comparison function that takes 6 arguments and returns 0 if the two dates are equal, <0 of the first date is less than the secnd date and >0 of the first date is greater than the secnd date.

This is the same setup used by strcmp so everyone is used to seeing it.

I can help with your code but I can't provide it.

"give some example to validate date accepted by user"... do you mean accepted or provided?
Take day... what integers would be valid for month of Jan?
Ans:>0 and <32. Write the algorithm then some code and show where your problems lie. Post it on this forum for help

We don't "provide" code, we will help if you have a problem with the code you have written. Consider these questions

1. What is the valid range of the year?
2. What is the valid range of the month?
3. What is the valid range of the day? Is it dependent on any other fields?

Also consider whether your application needs to work with a subset of valid dates. For example, a date-of-birth field might reject valid future dates and valid dates more than 120 years in the past.
