123abc123 二,标准库模板initializer_list initializer_list模板在函数声明中可以代表可变参数列表。 initializer_list中的参数可以使用迭代器来访问。 initializer_list实例中传入参数时需要使用{}把多个参数括起来。 代码样例: 代码语言:javascript 复制 initializer_list<int>i1{1,2,3,4}; Demo1: 初始化类成员 代码...
另一个可能的原因是使用了初始化表达式列表但未包含 initializer_list 标头<>。 C++ // C2065_initializer.cpp// compile with: cl /EHsc C2065_initializer.cpp// #include <initializer_list>intmain(){for(autostrList : {"hello","world"})if(strList =="hello")// C2065: 'strList': undeclared ...
