Process command line argument on windows

I need a hand in terms of processing command line argument (on Windows) in C.

Suppose I have the following situation

C:\Users\USER\Desktop> my_executable arg1 ' "A>200 && B<300 (just some conditions" '

In this case argc = 5

and 

C:\Users\USER\Desktop> my_executable arg1 '"A>200 && B<300 (just some conditions"'

In this case argc = 3

Depending on users, the argv and argc will be different. How can I write the code such that the condition and arg1 can be stored correctly :) Required: arg1 is stored into a char pointer condition is also stored into a char pointer

Thanks

Don't use single quotes as argument quotes on Windows unless you want to implement your own argument parser. ^ can be used to escape " and itself and a few other things. To embed " in arguments use "".

If you really need to, call GetCommandLineW and parse yourself. GetCommandLineW returns a string that consists of the executable image name possibly enclosed in double quotes, followed by an optional space and the arguments exactly as given to CreateProcess (which means that ^ processing has already taken place).
