The Seek (long Pos) method specifies the position of the current pointer, which is based on the number of bytes present in the system to locate the

Writeint writes an int value to the system by 4 bytes, a long is 8 bytes, and float converts the floating-point argument to an int in scientific notation, and then writes the int value to the file system by 4 bytes

The Readint method reads a signed 32-bit integer from the file system at its current location.
