the child class function (overriding function) gets called. What if you want to call the overridden function by using the object of child class. You can do that by creating the child class object in such a way
Example of Function OverridingBelow is a simple example illustrating how overriding works#include <iostream> using namespace std; // Base class class Shape { public: // Virtual method to be overridden virtual void draw() const { cout << "Drawing a shape" << endl; } }; // Derived class...

Functions with incorrect names: For example, if the virtual function in the base class is named print(), but we accidentally name the overriding function in the derived class as pint(). Functions with different return types: If the virtual function is, say, of void type but the function ...

The example below showcases the implementation of an inline function in C++.Code Example:#include<iostream> using namespace std; // Use the keyword "inline" to define an inline function inline int sum(int a, int b) { // Definition of inline function return a + b; } int main() { ...
您可以從 Visual Studio屬性視窗覆寫基底類別中定義的虛擬函式。 在[屬性] 視窗中覆寫虛擬函式: 在[類別檢視] 中,選取類別。 在[屬性] 視窗中,選取 [覆寫]按鈕。 備註 當您在 [類別檢視] 中選取類別名稱或在原始檔視窗內選取時,即可使用 [覆寫]按鈕。
Example The following example illustrates how you can use function overloads: C++ // function_overloading.cpp// compile with: /EHsc#include<iostream>#include<math.h>#include<string>// Prototype three print functions.intprint(std::strings);// Print a string.intprint(doubledvalue);// Print ...
