The position is computed from adding offset to a reference point; the reference point is selected by the whence argument. A whence value of 0 measures from the beginning of the file, 1 uses the current file position, and 2 uses the end of the file as the reference point. Webseekp () moves the put pointer to the desired location i.e. for write operation. seekg () moves the get pointer to the desired location i.e. for read operation. When we try reading a text file, the pointer is set to 0. So we read from the 0th pointer all the way to the last pointer. But if we want to read from a particular pointer, we use seekg (). do it yourself dog bathing
