C++ 输出错误（新增问题）

Question

我的程序似乎只运行完成 2 门课程，然后它停止并显示第二门课程 3 次。

我被难住了，拔头发，任何建议都会有很大帮助。

我也提前为冗长道歉post，但我觉得需要所有部分来确定问题。

这是当前的输出： Current output

我的预期输出是：

标题：标题课程 ID：12345 Session：54321 学分：1.2

这里是错误所在：

这是header：

这里是Course.cpp

    #include "Course.h"

    Courses::Courses()

    void Courses::setNumOfUnits(double units)

    void Courses::setSessionNumber(int session)

Answer 1

您的构造函数声明为 Courses(string title, int course, int session, double units)

但你称它为 Courses Class_1(title, session, units, course);

只要切换一下变量就可以了

Courses Class_1(title,course,session,units);
