文章目录1，c++类成员变量初始化顺序，和成员变量定义顺序保持一致，而和构造函数初始化列表中的顺序无关2，正确的写法1，c++类成员变量初始化顺序，和成员变量定义顺序保持一致，而和构造函数初始化列表中的顺序无关#include <iostream>class A { public: A(int a, int b):m_a(a), m_b(b),m_c(m_a + m_b) { std::cout << "m_a:" << m_a &lt

1，定义两个有虚函数的基类，一个派生类实现这两个基类的虚函数#include <iostream>class A { public: virtual void fun_a() = 0;};class B { public: virtual void fun_b() = 0;};class C :public A, public B{ public: void fun_a() override final { std::cout << "fu.

代码 结果

struct type { int i; std::string s; char *c; int a[2]; std::vector<int> v; std::map<std::string, int> m;};int main(){ std::cout << "hello" << st...

vector通过迭代器，使用eraser()删除元素后，该元素后面的vector部分会一次往前移动。1，创建一个vector，放入元素，并通过迭代器打印 std::vector<int> test_list; for(int i=0; i<5; i++) { test_list.push_back(i); } for(st...
