gets(a);
for (i=0;a[i]!='\0';i++);
i--;
for (j=0;j <= i/2 ;j++)
{
temp = a[j];
a[j] = a[i-j];
a[i-j] = temp;

Answer / vishnu
Try this ...
#include <stdio.h>
#include <stdlib.h>
int Rev (char *s, char *b)
{
int i ;
char c ;
if (*s == '\0')
{
return 0 ;
}
c = *s ;
i = Rev (s + 1, b) ;
b[i] = c ;
return i+1 ;
}
int main ()
{
int end ;
char str[] = "Billie jean is not my lover - MJ" ;
end = Rev (str, str) ;
str[end] = '\0' ;
printf ("Now [%s]\n", str) ;
exit (0) ;
}

/* Program to reverse any string input by the user without
using library function strlen( );*/
#include <stdio.h>
#include<conio.h>
void main()
{
char a[]={"sixaN: you are with us or against us"};
int i,len=0;
char *b;
clrscr();
b=a;
while(*b!='\0')
{
len++;
b++;
} //counting lenght of string
for(i=len;i>-1;i--)
printf("%c",a[i]); //printing charachters in reverse
getch();

Answer / right
char* reverseStringR(char* string){
if(string[0] && !string[1])
return string;
char first = string[0];
reverseStringR(string+1);
size_t length_rest = strlen(string+1);
memmove(string, string+1, length_rest);
string[length_rest] = first;
return string;
}
