*Under the documentation for the ESCAPE key, it says "your function needs to allocate memory at run time". I guess it means the temp chr array needs to match the original str in size, and that's a whole new headache read this: [http://www.cplusplus.com/faq/sequences/arrays/sizeof-array/ size of array]
I just want to know if we actually have to do this, or just setting the size of temp chr array to something large, say 81, will do. (It will pass the cio_test.cpp like that)
