Here is the given example representing both with this pointer in the Const member function Vs static member function.Open Compiler #include <iostream> class MyClass { public: MyClass(int val) : data(val) {} // Const member function (has 'this' pointer, but it's a const pointer) void ...
在C++ 中,this指针是一个特殊的指针,它指向当前对象的实例。 在C++ 中,每一个对象都能通过this指针来访问自己的地址。 this是一个隐藏的指针,可以在类的成员函数中使用,它可以用来指向调用对象。 当一个对象的成员函数被调用时,编译器会隐式地传递该对象的地址作为 this 指针。 友元函数没有this指针,因为友元不...
Type of 'this' pointer is "Class pointer" (or "Objet pointer") type - if there is a class named "Example" then, the type of 'this' pointer will be "Example*".Its type may depends on member function declaration in which the 'this' pointer is used. If the member function is ...

Transpose a matrix via pointer in C I'm trying to transpose a matrix in C while passing the matrix to a function and return a pointer to a transposed matrix. What am I doing wrong in the second while loop? in main create matrix transpos... ...
error C2662, cannot convert ‘this’ pointer from ‘const class ’ to ‘class &’ 看一下导致这个编译错误的例子: class COwnInt { public: int get(); private: int m_n; }; int COwnInt::get() { return m_n; } int main() {
这个错误在于一点:常量对象只能调用常量成员(函数\变量),不能调用非常量成员。另一方面,非常量对象,既可以调用常量成员,又可以调用非常量成员。 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 classA { public: voidfun_1() { std::cout <<"非常量函数"<< std::endl; ...

实际上,vbptr 指的是虚基类表指针(virtual base table pointer),该指针指向了一个虚基类表(virtual table),虚表中记录了虚基类与本类的偏移地址;通过偏移地址,这样就找到了虚基类成员,而虚继承也不用像普通多继承那样维持着公共基类(虚基类)的两份同样的拷贝,节省了存储空间。
