One good example would be c++ implementation of converting number to stream object.
Possible example:

What is the difference between \r and \n?
...ome compatibility situations where \r is used instead though.)
For more information, see the Wikipedia newline article.
EDIT: This is language-sensitive. In C# and Java, for example, \n always means Unicode U+000A, which is defined as line feed. In C and C++ the water is somewhat muddier, as the m...
