45 initialization of is skipped by 'case' label

initialization of 'XXX' is skipped by 'case' label 原因及解决办法编译时提示："error C2361: initialization of 'a' is skipped by 'default' label"。这怎么可能？出错原因： C++约定，在块语句中，对象的作用域从对象的声明语句开始直到块语句的结束，也就是说default标号后的语句是可以使用对象a的。如果程序执行时从switch处跳到default处，就会导致对象a没有被正确地初始化。确保对象的初始化可是C++的重要设计哲学，所以编译器会很严格地检查这种违例情况，像上述的示例代码中default语句后面并没有使用a，但考虑到以后代码的改动可能无意中使用，所以一样被封杀。明白了原因，解决起来就很容易了。只要明确地限制对象a的作用域就行了。 switch (t) { case 0: error C2360: initialization of 'i' is skipped by 'case' label ? - C / C++ My program has an error C2360: initialization of 'i' is skipped by 'case' label.
