c++bad-layout

/*************************************************************\
This is a bad example becasue the beginning and end of loops and function are not aligned.
The comments are place at the begining of the line. The case statment is spaced and organized
poorly, and the data declarations are also unaligned.
This makes the program difficult to read.
