问题描述

铸型与铸件之间有什么区别？类型转换在c ++。

Is there any difference between type casting & type conversion in c++.

推荐答案

一般来说，转换是指一个显式的转换，无论是通过C风格的转换c $ c> T（v）或（T）v ）或C ++风格的转换（ static_cast ， const_cast ， dynamic_cast 或 reinterpret_cast ）。转换通常是一个更通用的术语，用于任何时候将变量转换为另一个：

Generally, casting refers to an explicit conversion, whether it's done by C-style cast (T(v) or (T)v) or C++-style cast (static_cast, const_cast, dynamic_cast, or reinterpret_cast). Conversion is generally a more generic term used for any time a variable is converted to another:

std::string s = "foo"; // Conversion from char[] to char* to std::string
int i = 4.3; // Conversion from float to int
float *f = reinterpret_cast<float*>(&i); // (illegal) conversion from int* to float*
