C++ 使用setw（）正确格式化输出

还有别的方法吗？如果此代码的第节使其工作，但是否有任何方法可以使用setw（）正确组织（*）

void showTheater(char theater[][20],int row,int seat)
{
    cout << "Seats:  0  1  2  3  4  5  6  7  8  9 10 11 12 13 14 15 16 17 18 19" << endl;
    for (int i = 0; i <= row; i++)
    {

        for (int j = 0; j <= seat; j++)
        {
            if (j == 0) {
                cout << "Row " << i;
            }
            else if (i < 10) {
                cout << setw(3) << theater[row][seat];
            }
            else {
                cout <<" " << theater[row][seat]<<" ";
            }

        }

        cout << "\n";
    }
}

带有if部分的输出：

---

关键是使用

std:：setw

（与

std:：left

）作为行的索引。这是代码。请注意，现在星星也与标题对齐。在发布的代码中，

剧院

的索引也有错误

void showTheater(char theater[][20], int row, int seat) {
    std::vector<int> Seats (seat);
    for (int i = 0; i < seat; i++) Seats[i] = i;
    std::cout << "Seats:";
    for (int i = 0; i < seat; i++) std::cout << std::setw(3) << Seats[i] << " ";
    std::cout << "\n";

    for (int i = 0; i < row; i++) {
        std::cout << "Row " << std::setw(2) << std::left << i << " ";
        for (int j = 0; j < seat; j++) {
            std::cout << " " << theater[i][i] << "  ";
        }
        std::cout << "\n";
    }
}

void showTheater（char剧院[][20]，内排，内座）{
标准：：矢量座椅（座椅）；
对于（int i=0；istd：：是否可以将
setw
应用于
i
中的
i
您是否只需要对齐星号，或者也要对齐标题？使用printf（），有时比只处理星号要好。非常感谢。欢迎使用。如果此解决方案令您满意，您能否接受此答案？
