How do you want to split your file? Depending on what you want to achieve (split in half versus remove some header versus some other thing), the solution will be different.

It really depends on how complex the splitting will be. For a very simple kind of splitting it might suffice for you to use str_tok which breaks up a string on a specified set of delimiters. See here: http://www.cplusplus.com/reference/clibrary/cstring/strtok/[^].

For more complex work you may want to resort to using regular expressions[^]. See here for the MSDN documentation: http://msdn.microsoft.com/en-us/library/4384yce9(v=vs.80).aspx[^].

Cheers!
