Transcribed Image Text:Program Specifications
Write a function called rCopy that copies the entire contents of one file to another, but copies them over in reverse order. This function
should take the names of the input and output files as strings. If either file does not open for any reason, the function should output an error
message stating the name of the file that didn't open and then return the value false. Otherwise, if both files open correctly, the function
should return true once the reverse copy has been completed.
For example, if a file named in.dat contains the following:
A c d 87
arc 6587
9 9
then after the function call:
rCopy("in.dat", "out.dat")
the file out.dat should contain the following:
9 9
7856 cra
78 d c A
You must solve this recursively!! To implement this recursively you will need to write a helper function that passes in an input and an
output file stream. This helper function will be the recursive function. Recall that the expression cin.get(ch) will read in a single character
from cin into a char variable named ch.
Again, this must use recursion to get any points.
You may NOT use any kind of loop. You may NOT use global or static variables. You will be docked at least 20 points if you use a loop, a
global variable, or a static variable.
