c语言方阵转置

Map.put(keyword, accountList);
keywordJList.setListData(keywordList.toArray(new String[0]));
}
accountList.add(account);
textArea.append(account.toString() + "\n");
idTextField.setText("");
typeTextField.setText("");
costTextField.setText("");
在 C 语言中，可以使用二维数组来表示方阵。方阵转置的具体实现可以使用两 keywordTextField.setText("");
} else {
JOptionPane.showMessageDialog(this, "Invalid account information.");
}
});
saveButton.addActionListener(event -> {
int result = fileChooser.showSaveDialog(this);
if (result == JFileChooser.APPROVE_OPTION) {
data重循环遍历原数组，然后将原数组的第 $i$ 行第 $j$ 列的元素赋值File = fileChooser.getSelectedFile();
try {
BufferedWriter writer = new BufferedWriter(new FileWriter(dataFile));
for (Map.Entry<String,给转置数组的第 $j$ 行第 $i$ 列的元素。

以下是一个示例代码：

 ArrayList<Account>> entry : accountMap.entrySet()) {
                        String keyword = entry.getKey();
                        ArrayList<Account> accountList = entry.getValue();
                       #include <stdio.h>

#define N 3

void transpose(int mat[][N], int transposed[][N]) {
    int i, j writer.write(keyword + "\n");
                        for (Account account : accountList) {
                            writer.write(account.toString() + "\n");
                       ;
    for (i = 0; i < N; i++) {
        for (j = 0; j < N; j }
                    }
                    writer.close();
                } catch (IOException e) {
                    JOptionPane.showMessageDialog(this, "Failed to save data file.");
               ++) {
            transposed[j][i] = mat[i][j];
        }
    }
}

int main() {
    int mat[N][ }
            }
        });
        loadButton.addActionListener(event -> {
            int result = fileChooser.showOpenDialog(this);
            if (result ==N] = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9 JFileChooser.APPROVE_OPTION) {
                dataFile = fileChooser.getSelectedFile();
                try {
                    BufferedReader reader = new BufferedReader(new FileReader}};
    int transposed[N][N];

    transpose(mat, transposed);

    int i, j;
    printf("Original matrix:\n(dataFile));
                    String line;
                    while ((line = reader.readLine()) != null) {
                        String keyword = line;
                        ArrayList<Account");
    for (i = 0; i < N; i++) {
        for (j = 0; j < N; j> accountList = new ArrayList<Account>();
                        while ((line = reader.readLine()) != null && !line.isEmpty()) {
                            Account account = new Account(line);
                            accountList.add(account);
                        }
                        accountMap.put(keyword, accountList);
                        if (!keywordList.contains(keyword++) {
            printf("%d ", mat[i][j]);
        }
        printf("\n");
    }

    printf("Transposed matrix:\n)) {
                            keywordList.add(keyword);
                        }
                    }
                    reader.close();
                    keywordJList.setListData(keywordList.toArray(new String");
    for (i = 0; i < N; i++) {
        for (j = 0; j < N; j[0]));
                } catch (IOException e) {
                    JOptionPane.showMessageDialog(this, "Failed to load data file.");

    /**
     * 更新日历面板
     */
    private void updateCalendarPanel() {
        calendar.setTime(currentDate);
        calendar.set(Calendar.DAY_OF_MONTH, 1);
        int firstDayOfWeek = calendar.get(Calendar.DAY_OF_WEEK);
        int days`

这里的 `mat` 表示原方阵，`transposed` 是转置后的方阵，都是二维OfMonth = calendar.getActualMaximum(Calendar.DAY_OF_MONTH);
        calendarPanel.removeAll();
        String[] daysOfWeek = { "Sun", "Mon数组。在 `main` 函数中，先输出原方阵，然后调用 `transpose` 函数进行转置，最后", "Tue", "Wed", "Thu", "Fri", "Sat" };
        for (String dayOfWeek : daysOfWeek) {
            calendarPanel.add(new JLabel(dayOfWeek, JLabel.CENTER));
        }
        for (int i = 1; i < firstDayOfWeek; i输出转置后的方阵。可以看到，转置后的方阵矩阵的行列与原矩阵相反。
