这个错误信息“error: c++ requires a type specifier for all declarations”意味着C++编译器在编译代码时,发现某个声明缺少了类型说明符。在C++中,每个变量、函数返回类型、指针等都需要明确的类型说明,否则编译器无法正确理解和编译代码。 2. 指出可能导致该错误的常见原因 变量声明未指定类型:在声明变量时忘记了类...

For example, the String class is implicitly derived from Object. The benefit of sealing a class is that it supports the static resolution (that is, at compile-time) of all virtual function calls through the sealed reference class object. This is because the sealed specifier guarantees that the...
