Question:
I am doing a c++ project to check age from years,months.....femtoseconds. The problem is i am not getting the output required. i am getting correct
results upto agemils(age in milli seconds) then i get something e+xxxxx(x= number) like that. so i tried cout.precision() statement. then i dont get e+(exponential form(i guess!!)
but still i am not getting correct results. for conversion of milli to micro,micro to nano,nano to pico,pico to femto i just need 3 zeroes extra at every successive outputs keeping numbers same. but i am getting different numbers . this is quite strange i changed all data types. please help me with this problem soon.


Point out my mistakes and give new ideas (if any)

I am beginner to c++ so please explain me in detail

sorry for such a long question

use cout<<fixed

[his111]

where and how to use that?

So you have no Birth day? You do have Birth year & month & hour, but no day?

Please post your code in code tags - the <> button on the right.

You are using goto's which is really bad - forget they even exist. You need to put inside a while loop to achieve the same thing.

You should put more things into functions, rather than having a heap of code in one lump. It will be much more organised.

Google is your best friend. Use it to check things out. There is a heap of reference stuff on this site - read some of it.

Good luck !!
