int main()
{
int a[5][4] = {{1, 1, 1, 1}, {2, 2, 2, 2}, {3, 3, 3, 3}, {4, 4, 4, 4}, {5, 5, 5, 5}};
for (int i = 0; i < 5; ++i)
{
int sum = 0, avg = 0;
for (int j = 0; j < 4; ++j)
{
sum = sum + a[i][j];
}
printf("row %d %.2f\n", i + 1, float(sum / 4));
}
for (int j = 0; j < 4; ++j)
{
int sum = 0, avg = 0;
for (int i = 0; i < 5; ++i)
{
sum = sum + a[i][j];
}
printf("col %d %.2f\n", j + 1, float(sum / 5));
}
}
