字面意思为没有默认的构造函数,但是仔细的检查了自己的类的定义和实现,其中已经实现了无参的构造函数,而且new 的语法部分也没有错误 既然系统说找不到默认的构造函数,也就是说编译器在进行解析的过程中出现了类似于函数未定义的错误,那么是不是自己的类的定义位置出现了问题 ...
错误提示说得很清楚了，没有合适的构造函数 你的Graduate类的构造函数是 Graduate(string n,string s,int a,string t,float sc,float w):Person(n,s,a),Teacher(n,s,a,t),Student(n,s,a,sc),wages(w){} 而你生成对象时 Graduate g;参数表为空，所以你得按构造函数的参数表，传入参数 ...
Because there is no default constructor available in B, as the compiler error message indicates. Once you define a constructor in a class, the default constructor is** not included.** If you defineanyconstructor, then you must defineallconstructors. ...
没有合适的的构造函数！！！你重新定义了一个构造函数，默认的无参数的构造函数就会被编译器取消掉。所以，就有这样的提示了。no appropriate default constructor available 翻译：没有有效的适合的默认构造函数。
