pointing to the last character

[brown monkey]

how do i do this? i do

char *s="brown monkey"
char *p=s;

to point to the first character of s.

[CornedBee]

First
char *s = "literal";
is not quite valid, it should be
const char *s = "literal";
and thus
const char *p = s;


To get the last character,
p = s + strlen(s) - 1;
strlen comes from <string.h>.

This is pure C, in C++ you'd be better off using std::string.

thanks corned. it helps. but my code

#include<string.h>
main(){
   const char *s="brown monkey";
   const char *p=s+strlen(s)-1;
   char *t;
   while(*--p)
      *t++=*p;
   printf("%s",t);
}

throws

am i missing something? i'm trying to do a strrev function of my own. thanks.

There's no memory attached to t, it points to a random location.

Learn a lot about string handling in C from a book or online tutorial.
