using namespace std;

const int MONTHS = 3;
int main()//w  ww .  jav  a 2 s  .co  m
{
   int d, m;
   double sales[DISTRICTS][MONTHS];  //two-dimensional array
   //definition
   cout << endl;
   for(d=0; d<DISTRICTS; d++)        //get array values
      for(m=0; m<MONTHS; m++)
       {
          cout << "Enter sales for district " << d+1;
          cout << ", month " << m+1 << ": ";
          cin >> sales[d][m];         //put number in array
       }

      for(m=0; m<MONTHS; m++)        //display array values
         cout << setiosflags(ios::fixed)      //not exponential
