char* strrev(chr* src)
{      
       char* dest
       int len=0, index=0 , rindex=0;

       while(*(src+len) != '\0')
       { len++ }

       rindex=len-1;

       while(rindex > =0)
       {
           *(dest+index) = *(src + rindex)
            index++;
            rindex--;
       }

      *(dest+index) = '\0';


return dest;
}
