Connect and share knowledge within a single location that is structured and easy to search.
给定以下课程:
class MyRecord { public: int a; int b; MyRecord() : MyRecord(8, 9) {}; MyRecord(int a, int b) : a(a), b(b) {}; };
初始化向量的最简单方法是什么: std::vector<MyRecord> myVector使用一些数据?
std::vector<MyRecord> myVector
通过示例演示:
MyRecord exampleRecord(3,4); std::vector<MyRecord> myVector = {{1,2}, {}, exampleRecord};
为了验证,下面的代码
for (MyRecord &record : myVector) { std::cout << "a:" << record.a << " b:" << record.b << std::endl; }
将输出:
a:1 b:2 a:8 b:9 a:3 b:4
