For example, one practise is to explicitly instantiate a template for distinct set of parameters in one .cpp file and declare those instantiations extern in the header. This way, those instantiations can be used in other source files without requiring the implementation of the t...
voidsetInstructorName(std::string);// declaration in .hvoidGradeBook::setInstructorName()const// implementation in .cpp See the difference? Your implementations are missing thenameparameter and have trailingconstmodifiers. You need to correct those mistakes: voidGradeBook::setCourseName(std::string ...

2在C语言中,如果函数在声明之前被调用,如果对函数的参数做检测? compiler assumes nothing about parameters. Therefore, the compiler will not be able to perform compile-time checking of argument types and arity when the function is applied to some arguments. This can cause problems. 编译器对参数不做...
