 memmove() function

                   It copies the number of bytes from located pointed of source and it again copied into the located point of destination,In this case,the overlap will be occurring in the destination. i.e memmove() function.

syntax
              void *memmove(void *destination,void *source,size_t count);

 Program
            
                 #include<stdio.h>
                 main()
                 {
                       char str[] = "Programming";
             
                            memmove(str+1,str+3,4);

                     printf("After memory move  : %s\n",str);
                  }

    Output
                  After memory move :Pgramamaing

         Explanation 
                                 a[0]   1   2   3   4   5   6   7   8   9   10
                                   P     r    o   g    r    a   m  m   i   n     g
                    In memmove(str+1,str+3,4) function,from a[3] position to 4 bytes (a[6]) are copied and overlapped in destination string.So output is Pgramamaing.
