i am working on a project to synchronize the clock through GPS time and date , i am unable to find the exact code to do it. i am using GPS receiver which is connected to my system through rs 232 so i want to store the GPS date and time in a array coming out of gps serial string and then use it for synchronization of my clock.
Either i want to use $GPRMC or $GPZDA message to fetch and store the information

please help me through this as i am breaking my head on this for many days

What I have tried:

i have tried to sync it though a software which requires no code just a setting of gps com port but, now i want to do it with code which can store the info in a array

So what is the problem / question?

Serial communication?
Parsing a string?
Defining a structure to store the parsed data?
Convert to a common datetime structure?
Setting the system clock?

Programming is not looking for existing code that does what you want. You will usually not find code that does exactly what you want. While you can adapt existing code, you have to understand what the code is doing to verify that it is doing it right.

I asked you to tell us what your problem is. I understand what you want to do.
But this is Quick Answer and not "give me code for my task". We will help if you got stuck with code already written by you and general programming related questions.

Again:
Programming is not (re-)using existing code. It is analysing problems and solving it by writing your own code. For specific tasks, it might help to see example code on how it can be done. But you have to split your problem into tasks first and solve each step by step.

I would add to Jochen Arndts comments. This is just too vague a question. Is it Arduino, Windows, Android, RaspPi or what? Parsing NMEA sentences is quite easy to implement, there is a lot of example code out there - you can google that just as easily as we can. Remember this is a technical forum so give details of what you are attempting and what the problem is. You can use improve question to add more details.

You should provide more details in order to get better help. For instance what is your hardware (PC or micrcontroller)? What is your OS (if any)? Why are you using C programming language? And so on...

i am working on DOS n i want to fetch the time and date from $GPRMC or $GPZDA string using c.
I want to ask about ibcom serial library will it be helpful?
