如果要形成一个可视化的柱和盘呢？

如果要形成可视化的柱和盘，可以使用图形界面库来实现，例如Windows下的Win32 API，或者跨平台的Qt等。这里给出一个使用Qt实现的汉诺塔可视化程序的示例代码：

#include <QApplication>
#include <QWidget>
#include <QHBoxLayout>
#include <QVBoxLayout>
#include <QPushButton>
#include <QLabel>
#include <QLineEdit>
#include <QComboBox>
#include <vector>
using namespace std;

class Disk : public QLabel {
public:
    Disk(int size, QWidget *parent = nullptr) : QLabel(parent) {
        setText(QString(size, '#'));
        setAlignment(Qt::AlignCenter);
        setStyleSheet("background-color: #FFC0CB; border-radius: 5px;");
    }
};

class Tower : public QWidget {
public:
    Tower(QWidget *parent = nullptr) : QWidget(parent) {
        QVBoxLayout *layout = new QVBoxLayout(this);
        layout->setMargin(0);
        layout->addStretch();
    }

    void addDisk(int size) {
        Disk *disk = new Disk(size, this);
        QVBoxLayout *layout = static_cast<QVBoxLayout *>(this->layout());
        layout->insertWidget(0, disk);
        disks.push_back(disk);
    }

    void removeDisk() {
        QVBoxLayout *layout = static_cast<QVBoxLayout *>(this->layout());
        delete layout->itemAt(0)->widget();
        disks.pop_back();
    }

    int topSize() const {
        if (disks.empty()) {
            return -1;
        }
        return static_cast<int>(disks.back()->text().size());
    }

private:
    vector<Disk *> disks;
};

class MainWindow : public QWidget {
public:
    MainWindow(QWidget *parent = nullptr) : QWidget(parent) {
        setWindowTitle("汉诺塔");
        setFixedSize(800, 600);

        QHBoxLayout *layout = new QHBoxLayout(this);
        layout->setMargin(30);

        for (int i = 0; i < 3; i++) {
            Tower *tower = new Tower(this);
            layout->addWidget(tower);
            towers.push_back(tower);
        }

        QVBoxLayout *buttonLayout = new QVBoxLayout();
        buttonLayout->setAlignment(Qt::AlignTop);

        QLabel *label1 = new QLabel("盘子数量：");
        buttonLayout->addWidget(label1);

        QLineEdit *lineEdit = new QLineEdit();
        buttonLayout->addWidget(lineEdit);

        QLabel *label2 = new QLabel("移动方式：");
        buttonLayout->addWidget(label2);

        QComboBox *comboBox = new QComboBox();
        comboBox->addItem("A -> B");
        comboBox->addItem("A -> C");
        comboBox->addItem("B -> A");
        comboBox->addItem("B -> C");
        comboBox->addItem("C -> A");
        comboBox->addItem("C -> B");
        buttonLayout->addWidget(comboBox);

        QPushButton *button = new QPushButton("移动");
        connect(button, &QPushButton::clicked, this, [=](){
            int from = comboBox->currentIndex() / 2;
            int to = comboBox->currentIndex() % 2;
            moveDisk(from, to);
        });
        buttonLayout->addWidget(button);

        QLabel *label3 = new QLabel("操作说明：");
        buttonLayout->addWidget(label3);

        QLabel *label4 = new QLabel("1. 输入盘子数量后按回车；");
        buttonLayout->addWidget(label4);

        QLabel *label5 = new QLabel("2. 选择移动方式后点击移动按钮；");
        buttonLayout->addWidget(label5);

        QLabel *label6 = new QLabel("3. 操作错误时会有提示信息。");
        buttonLayout->addWidget(label6);

        layout->addLayout(buttonLayout);
    }

    void moveDisk(int from, int to) {
        if (from == to) {
            return;
        }
        Tower *pFrom = towers[from];
        Tower *pTo = towers[to];
        if (pFrom->topSize() == -1) {
            QMessageBox::warning(this, "错误", "移动的起始塔没有盘子！", QMessageBox::Ok);
            return;
        }
        if (pTo->topSize() != -1 && pFrom->topSize() > pTo->topSize()) {
            QMessageBox::warning(this, "错误", "不能把大盘子放在小盘子上面！", QMessageBox::Ok);
            return;
        }

        pTo->addDisk(pFrom->topSize());
        pFrom->removeDisk();

        if (towers[2]->topSize() == n) {
            QMessageBox::information(this, "提示", "恭喜你完成了汉诺塔的移动！", QMessageBox::Ok);
        }
    }

private:
    vector<Tower *> towers;
    int n;
};

int main(int argc, char *argv[]) {
    QApplication app(argc, argv);

    MainWindow window;
    window.show();

    return app.exec();
}

这个程序使用Qt的图形界面库，实现了汉诺塔的可视化效果，用户可以选择盘子数量和移动方式，并通过点击移动按钮来移动盘子，程序会判断移动是否合法，如果不合法则会提示错误信息。
