1)

-Get input from the user any way you like. getch() or whatever.
-Then just use a for loop.
Code:
for (int i = 0; i < MAX_ARRAY_ELEMENTS; i ++)
   array[i] = input_from_user;
2)

Simular to the first.

Code:
for (int i = 0; i < MAX_ARRAY_ELEMENTS; i ++)
{
   if (array2[i] != 0) //we dont want division by zero
      Result[i] = array1[i] / array2[i];
   else
      Result[i] = 0;
}
