int[][] score = new int[][] { { 33, 22, 56, 45, 33 },
{ 77, 33, 68, 55, 21 }, { 21, 44, 45, 33,56 } };
int sum = 0;
for (int i = 0; i < score[0].length; i++) {
for (int j = 0; j < score.length; j++)
{
sum += score[j][i];
}
System.out.println("第" + (i + 1) + "列的和为" + sum);
}
{ 77, 33, 68, 55, 21 }, { 21, 44, 45, 33,56 } };
int sum = 0;
for (int i = 0; i < score[0].length; i++) {
for (int j = 0; j < score.length; j++)
{
sum += score[j][i];
}
System.out.println("第" + (i + 1) + "列的和为" + sum);
}
