要解决'no matching function for call to'错误,需要确保函数调用与函数定义匹配。以下是详细说明: 1、相关编程概念解释: 'no matching function for call to' 是 C++ 编译器在编译时抛出的一个错误,表示程序尝试调用一个函数,但编译器无法找到与函数调用匹配的函数声明或定义。这通常是因为函数的参数类型、个数、...
最近初学Qt,在做项目的过程中遇到 E:\QT Project\WinCalculater\mainwindow.cpp:132: 错误:no matching function for call to 'MainWindow::connect(MyButton*&, void (MyButton::*)(), MainWindow* const, const char*)' 的问题,然后我就上网查错误的原因,但是查到的答案都没有解决我的问题,后来自己发现...
test.cpp:4: error: no matching function for call to ‘Statuslogfile::Statuslogfile(const char [8])’这个错误是由于构造函数接受的输入是字符串(char*),而不是常量字符串(const char*),你用“log.dat"作为参数的话就会出现找不到匹配的构造函数的错误了。如果先赋值一个字符串char* str...
1. no matching function for call to / no matching function for call If function call and function definition arguments are not matching then you might get this error. Depend on compiler to compiler you might get different errors. Sometimes it also give that type mismatch or can not convert f...

'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...
