Sorry ...correction we have to bring temp2 to last char again...!!!! so
char* temp, temp2;
char* s="Nitin";
for(temp2=s;*temp2='\0';temp2++ );/*just to calculate the length of s*/
--temp2; *<===================*
void strrev(char * s,char* temp2)
{ if (s==temp2 ||s>temp2)
{return;}
*temp = *s;
*s=* temp2;
*temp2=*temp;
temp2++;
s++;
strrev(*s,*temp2)
}
