     len--;

     printf("%s%s ",p,str2);
  }
  while(p=strtok(NULL," "))
  {

     len=strlen(p);
     for(i=0;i<len;i++)

Answer
Hi Dear Cathy !

Here i made some corrections with your programme , actually your programme is almost near to the expected result  but there you commit a mistake

take a look at this statements !

>>
for(i=0;i<len;i  )
{
p[i]=p[i 1];
}

You have moved the characters 1 step forward but you failed to restore the 1st character in the array to the last position . In order to rectify this problem ,  ive used a temporary variable "temp" to store the first character in the array say p[0] , that after the successful shipment of all the characters to 1 position left ,  the last position say  p[len-1] is replaced with temp.

Debugged code!

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

void main()
{
char *str1;
char *str2={"ay"};
char *p;
int i;
int len;
char temp;
clrscr();
printf("Enter String: ");
gets(str1);


p=strtok(str1," ");

if(p)
{
  len=strlen(p);
  temp = p[0];
  for(i=0;i<len;i  )
  {
     p[i]=p[i 1];
  }
  p[len-1] = temp;
  printf("ss ",p,str2);
}
while(p=strtok(NULL," "))
{

  len=strlen(p);
  temp = p[0];
  for(i=0;i<len;i  )
  {
     p[i]=p[i 1];
  }
  p[len-1] = temp;
  printf("ss ",p,str2);
}
getch();
}


Thanks and Regards !
