"The three file stream data types are" , , and . If a file fails to open, the file stream object will be set to . Design a pseudocode algorithm for determining the length of a file (the number of bytes that are stored in the file). Design a pseudocode algorithm for comparing two files to see if their contents are identical. Design a pseudocode algorithm for reversing the content of one text file into another file. Assume that the amount of memory is limited, so that you cannot read the entire source file into memory before you start writing it into the second file in reverse order.
