static_cast<>和C风格铸造？ [英] What is the difference between static_cast<> and C style casting?

问题描述

有什么理由比C风格的转换更喜欢 static_cast<> 吗？它们是等效的吗？是他们的任何种类的速度差异？

Is there any reason to prefer static_cast<> over C style casting? Are they equivalent? Is their any sort of speed difference?

推荐答案

C ++样式转换由编译器检查。 C风格的cast不会，并且可以在运行时失败

C++ style casts are checked by the compiler. C style casts aren't and can fail at runtime

也可以很容易地搜索c ++风格的cast，而很难搜索c风格的casts

also, c++ style casts can be searched for easily, whereas it's really hard to search for c style casts

另一个大的好处是4个不同的C ++风格的转换更清楚地表达了程序员的意图。

Another big benefit is that the 4 different C++ style casts express the intent of the programmer more clearly.

编写C ++时，几乎总是使用C语言的C语言。

When writing C++ I'd pretty much always use the C++ ones over the the C style.
