no matching function for call to 'CDate::CDate()'你需要在CDate中定义参数为空的构造函数 SB(){};当调用这个构造函数的时候，成员CDate也会调用参数为空的构造函数，因为没有定义，所以报错了，你需要在类CDate中加上 CDate(){}
'CPoint::CPoint(CPoint)' 你在代码中没有对CPoint(CPoint)这类型的构造函数进行定义，所以找不到 该函数
include <iostream> using namespace std;class CPerson { public:void Print();CPerson(int a, const char *b); //必须公有，要带参数 private:int age;char name[50]; // 若用 *name，则要加动态分配存储空间 };CPerson::CPerson(int a, const char *b){ age=a; strcpy(na...

这是因为模板参数推导对std::initializer_list的元素拒绝隐式转换,如果你把to_array的模板参数从int改为uint32_t,会得到如下编译错误: D:\Work\Source_Codes\MyProgram\VSCode\main.cpp:51:61: error: no matching function for call to 'to_array(<brace-enclosed initializer list>)' auto g_cfgPara = to...
It also made it possible to introduce two new code inspections: Ambiguous call: No matching function to call: This work addresses a huge list of issues from the tracker and most likely a lot of problem not yet even reported to us. Thus we kindly ask you to check the update and log any...
