How to convert char chA[14] to char *pointerA???

ifstream myInputFile("thisFile.txt");
if( !myInputFile )
{
	perror("File could not be opened");
}
	
char chA[14];
myInputFile.getline(chIPAddress, 14, '\n');

I need to convert to char *,
becouse of this:

(Toggle Plain Text)

sockaddr_in clientService;
clientService.sin_addr.s_addr = inet_addr( pointerA );

i try to use char chA for inet_addr(chA),
but it has error.

Please help... thanks

I recommend you begin by reading up on pointers. There's a link in my signature to "pointer basics". While there is some equivalency between pointers and arrays, they are not precisely the same thing.
