how can i convert simple integer value to years, months and days with taking care of leap year, and also 31 day of months.
like i have entered 364 then answer will be 11 months and 30 days..
or if entered 366 then it should be 1 year, 0 month and 1 day..
please help me. i have already the simple code but it is not giving me correct answer.
it is giving the answer if i entered 364 the 12 months and 4 days so its wrong but it seems right for big amount of value. so i need the exact code..
the code is given above.

Thanx

send your code, then let's talk about it.

There is no solution to this, as months and years do not have a fixed length. The result of the conversion will always depend on what months and what year you are looking at!

Likely you've misinterpreted the task you've been given, or if you've come up with it by yourself, you should reconsider what is the goal of that calculation. For instance banks like to average month to day ratios for the purpose of calculating day-to-day inertest rates.

there are many points here. first you should define an array to hold number of days for each month. if you want to take account of a leap year, then number of days becomes meaningless, because without knowing specific year (2012) you cannot talk about leap year. assuming that there is a specific year in the problem, then you should update #of days for February for leaps years. therefore I agree to Stefan_Lang.

There is no "direct" solution: you can't have a "months" count without knowing the start date, including the year - as the length of February changes every four years.

But... if you want to accept inaccurate answers which assume a 30 day month as in your code, then it's easier than your think - sort of.

C++

years = days / 365;
days = days % 365;
months = days / 30;
days = days % 30;

Since you are using integers throughout, the divide throws away any fractions, then the modulus throws away the bit you just calculated!

But do be aware: it produces rubbish results in the real world: such as 1 year, 12 months, 4 days if you enter 729!
