@gengchl 1&gt;c:\users\lenovo\desktop\one\one.cpp(22): error C2664: “Teacher::Teacher(double,std::string,double,double)”: 不能将参数 2 从“double”转换为“std::string”

[gengchl]

    AssociateProfessor(double dClassHour,string sName,double dFixedWage=3000,double dPeriodAllow=30):Teacher(dFixedWage,dPeriodAllow,sName,dClassHour){};

是不是因为这句？Teacher（）的第三个参数之前都是dClassHour，在这里变成sName了。

[Andy1989630]

 AssociateProfessor(double dClassHour,string sName,double dFixedWage=3000,double dPeriodAllow=30):Teacher(dFixedWage,dPeriodAllow,sName,dClassHour){};

sName跟dClassHour互换一下位置
