我有一个程序，让用户输入他们的姓名、年龄和他们上过的课程。这些类作为二维字符数组存储在 main() 函数中，然后将它们传递给 Student 类中的函数，该函数将该数组复制到名为 m_CourseNames 的公共成员 const char* 数组中。我已使用 CLion 中的调试器验证此过程已成功完成。
但是，exit code 11每当我尝试遍历 m_CourseNames 数组并将其内容打印到屏幕上时，程序就会崩溃。
我尝试通过以下方式将数组打印到屏幕上：
在主函数中：
for (int count = 0 ; count < 9 ; count++) cout << student.m_CourseNames[count] << " ";通过调用 via 在学生类的成员函数中
student.getCourses();：for (int count = 0 ; count < 9 ; count++) cout << m_CourseNames[count] << " ";在一个重载的运算符函数中，使用与 1) 中相同的方法（请参阅代码以了解我为什么在这里尝试它）
在程序完成之前，尝试将 const char* 数组打印到屏幕的所有三种方式都导致以下错误代码：
如果数组是公共成员变量，不知道为什么不会迭代。调试器验证所有类都正确存储在其中，因此它不是 addCourses() 函数的责任。
请参阅下面的整个程序（注释掉的所有内容都是尝试将数组打印到屏幕上）：
