Can one (re)set all the values of an array in one line (after it has been initialized)?

Question

In C, I know I can make an array like this

int myarray[5] = {a,b,c,d,e};

However, imagine the array was already initialised like

Here is a solution that is all standards compatible (C89, C99, C++)

It has the advantage that you only worry about entering the data in one place. None of the other code needs to change - there are no magic numbers. Array is declared on the heap. The data table is declared const.

#include
#include

int main()
{
unsigned int i = 0;
int *myarray = 0;
static const int  MYDATA[] = {11, 22, 33, 44, 55};

  myarray = (int*)malloc(sizeof(MYDATA));
  memcpy(myarray, MYDATA, sizeof(MYDATA));

  for(i = 0; i < sizeof(MYDATA)/sizeof(*MYDATA); ++i)  
  {
    printf("%i\n", myarray[i]);
  }

  free(myarray);

  return 0;
}
