/* 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();


Output :
