Problem: A water question but taught me how to use GetChar (), when all the data is read in the data in the cache before the return, enter the cache after the start of the data read into the program, so the problem, can be a one to get each character, then processing, and then output

Another detail in the code is that \ is a transfer character, and \ \ represents a character representing \, which occupies only one char space
