In general, it is possible to move to any position in a file stream. This is a capability most programmers use rarely, if at all. For fairly obvious reasons, don't try to use repositioning operations on the standard input, output, or error streams.The most likely reason for using a repositioning command is to rewind a file to the start, so that you can read its contents again. This is done as follows:fp_in.clear(); // forget we hit the end of filefp_in.seekg(0, ios::beg); // move to the start of the file
