SYNOPSIS
#include <publib.h>
char *strrev(char *str);
DESCRIPTION
strrev reverses the argument string in place, i.e., it swaps the ith character from the beginning with the ith character from the end.RETURN VALUE
strrev returns its argument.EXAMPLE
Reversing "dlrow, elloh" would be done like the following.
char str[] = "dlrow, elloh"; puts(strrev(str));This would output "hello, world". Note that using the string literal as the argument would be an error, since it is not allowable to modify string literals.
