check for errors in opening the files

(1) Write a program to prompt the user for an input and output file name. The program should check for errors in opening the files, and print the name of any file which has an error, and exit if an error occurs. For example, (user input shown in caps in first line, and in second case, trying to write to a folder which you may not have write authority in) Enter input filename: DOESNOTEXIST.T Error opening input file: DOESNOTEXIST.T Enter input filename: SOURCE.CPP Enter output filename: .. Error opening output file: .. (2) It should copy the input file, line by line, to the output file and to standard output so you can see it working (3) Before the program exits, it should close all files. (4) You will have to manually look at the output file to confirm the program ran correctly. A sample input file is listed below for your testing, or you may use source.cpp as your input to see your code copied to the output file. If you use our sample file, copy/paste the text into a new .txt file in the same folder as your source.cpp file, or your program won't be able to find it. For example, (based on the input file we provide you, with user input shown in caps) Enter input filename: FB.TXT Enter output filename: O.TXT File text: Copy this text file, exactly, line by line, without losing any words or whitespace. Sample input file “FB.TXT” which generated the above output: Copy this text file, exactly, line by line, without losing any words or whitespace.
