    Exactly what do you have problems with? Showing some coding attempt will most likely motivate people to help rather than flame for asking to do homework.

    It doesn't get any easier by trying to study what others have done for you.

    At least you should be able to
    - prompt for input
    - read year, month and day values
    - print "You were born on "

    Show us that you can at least do that much.

    If at first you don't succeed, try writing your phone number on the exam paper.

    Code:
    #include<windows.h>
    #include<iostream>
    using namespace std;
    main(){
    
    SYSTEMTIME st;
           
        GetSystemTime(&st);
    
    cout<<st.wYear;
    }
    here is the code that prints the system year.


    and here is the SYSTEMTIME structure for your reference:
    typedef struct _SYSTEMTIME {
    WORD wYear;
    WORD wMonth;
    WORD wDayOfWeek;
    WORD wDay;
    WORD wHour;
    WORD wMinute;
    WORD wSecond;
    WORD wMilliseconds;
    } SYSTEMTIME


    so u can use whicever field u want.actually i am still using the c api,if u want c++ wrapper classes refer to mfc(CTime class).

    can u do it from here or u want more help?

    In C there is no magic or standard way to do what you want. In C++ there are classes that will take two dates and return the difference.

    The functions in time.h should help you. time() will return current system date as an unsigned integer. Then convert the birth date to struct tm and call mktime() which will return the values of struct tm into an integer. Then just subract the two integers. That will give you the difference in seconds. Finally convert the difference into years, months and days.

    Show some effort will you!

    You do the work, we help you sort out the problems - you're never going to learn anything by just begging people to do the work for you.

    5 posts of begging.
    Not a single line of code showing any attempt at anything.
