Question

Hello. I'm working on decompressing text in run length encoding in C++. I'm almost finished with the code but I'm confused about how to fix the whitespace.

Program requirements:

Do not forget to close the file after you are done with it.
You must use a while loop to handle the loop reading information from the file.
You must use a for loop to handle the count/char output.
Use the sample runs to ensure that all output is spelled/spaced correctly.

Hint:

You will need to make use of .get(ch) to "throw out" the irrelavent spaces. With stdin you would have used std::cin.get(ch), however with file objects remember you will need to use file_obj.get(ch) .

Sample Run 3 (simplestring.txtas input)
Enter filename to decompress: simplestring.dat
RRRRRRRRRRRRRGGGGGGGGGRRRRRRRRRRBBRRRRRRRRRRRGGGRGRGGGGBBBBBBRRRRRRRR
Sample Run 4 (cat.txt as input)
Enter filename to decompress: cat.txt
/// //_.-' .-/";
///_.-'
|/ (_..-' // (<

Sample Run 5 (horse.txt as input)
Enter filename to decompress:
