Hi everyone. wel l i wanted to know if it was possible to assign the date of today[ date stored in the os time system] to a particular variable and then i will be using that date to know when a particular line of text has been input in of of my data file..
or simply is there a function for this?? Else if this is not possible then ill have to ask the user to enter the date during program execution, but this seems a bit lengthy.. please do suggest.. thnks in advance.
There are a bunch of functions to do that in "time.h". Ideally, you want to store the content of a "struct tm", which is a standard format struct. Several functions return a "time_t" type, which is implementation dependent, so if you store that value, it will not work right if you move to another system.
Here are some references to the basic "time()" function call, which returns the current time in a time_t type - you then have to convert that with for example localtime() or gmtime()

http://www.hmug.org/man/3/ctime.php (gives localtime and friends)

thanks i will try it... also is there somewhere i can find the different functions that i can use with a particular file header?? such a <stdio.h> <math.h>..
There should be some reference books and web-sites. www.cppreference.com does it for C++ (but includes the C standard libraries too, although stdio.h would be called cstdio - it's the same thing, just converted so that it works with C++ includes really).
