static_cast<>在 C++ 中是一种用于执行显式类型转换的运算符,它在编译时检查类型转换的有效性,比 C 风格的强制转换(如(int)x)提供了更强的类型检查。 基本类型之间的转换 用于基本数据类型(如 int、float、double 等)之间的转换,使得不同类型的数据可以进行操作。

在C++中,有 4 个强制类型转换运算符,分别是:static_cast、dynamic_cast、const_cast 和 reinterpret_cast。 2.2.1、static_cast 静态强制转换,用于实现任何标准类型间的转换。 2.2.2、dynamic_cast 动态强制转换,用于基类 和 派生类对象之间的指针转换,以实现多态。
