SYNOPSIS
#include <publib.h>
char *strrot13(char *str);
DESCRIPTIONstrrot13 converts the argument string using rot13, i.e., it replaces
each letter a with n, n with a, b with o, o with b, and so on. Con‐
verting twice results in the original string. Non-letter characters
are not converted.
The rot13 encryption method is used commonly on USENET to hide offen‐
sive text, or spoilers in discussions about movies or books, or in
other similar occasions.
RETURN VALUEstrrot13 returns its argument.
