#include<stdio.h>
#include <string.h>

char * reverse (char *); //function prototype
int length(char *); //function prptotype

void main()
{
int i;
char *str, *rev;
clrscr();
gets(str);
strcpy(rev,reverse(str));

printf("Original %s Reverse %s", str, rev);
free(str);
free(rev);
getch();
}

int length(char *s)
{
int i;
for (i=0; *(s+i)!='\0' ; ++i);
return i;
}

char *reverse(char *s)
{
char *t;
int i, n;
n=length(s);
for (i=0; i<n; ++i)
{
*(t+i)=*(s+n-1-i);
}
*(t+i)='\0';
printf("\nOUT: %s\n", t);
return t;
}
