These functions seekg() and seekp() requires an argument of type ____________to determine that how many bytes to be move forward or backward.

The functions seekg() and seekp() require an argument of type streampos or streamoff to determine how many bytes to move forward or backward. These are specific types defined in the C++ Standard Library for representing positions within a stream and offsets from a position, respectively.

Here's a step-by-step explanation:

1. seekg() and seekp() are functions used in file handling in C++. seekg() is used for input (read operations), while seekp() is used for output (write operations).

2. These functions are used to change the position of the 'get' and 'put' pointers in the file. The 'get' pointer determines where the next character to be read from the file is, while the 'put' pointer determines where the next character to be written to the file is.

3. The argument passed to these functions determines the new position of the respective pointer. This argument can be of type streampos or streamoff.

4. streampos is a type that represents a specific position within a stream. It's typically used when you want to set the pointer to a specific position.

5. streamoff is a type that represents an offset from a position. It's typically used when you want to move the pointer a certain number of bytes forward or backward from its current position.

6. So, if you want to move the pointer forward or backward by a certain number of bytes, you would use an argument of type streamoff with seekg() or seekp().
