Convert integers, floating-point values and enum types to enum types. (int float转enum) // copied from zhihuinti, j;doubleslope =static_cast<double>(j) / i;void*p = &d;double*dp =static_cast<double*>(p); dynamic
int coloe=static_cast<int>(MyNamespace::Colors::Red); 相信很多人跟我一样,想知道强枚举的实现方式,此次借助cppinsights来分析下,仍然是上面的代码: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 namespace MyNamespace{enumclassColors:int{Red,Green,Blue};} 看了上面代码的第一眼,就好奇enum cla...

②用于基本数据类型之间的转换,如把int转换成char,把int转换成enum。这种转换的安全性也要开发人员来保证。 ③把空指针转换成目标类型的空指针。 ④把任何类型的表达式转换成void类型。 注意:static_cast不能转换掉expression的const、volitale、或者__unaligned属性。
