* Challenge: write this function without
* using any library functions;
* void GetInt(char *strint, int val);
* this function gets an integer value and
* converts it to a string ("strint")
*
* My lean and mean version has lots of
* notes but very little code. I include
* a main()and two additional functions
* for display.
*
* I changed the brackets so that the code
* will be easier to read on this blog.
