Multiple inheritance is a type of inheritance in which a class derives from more than one class. As shown in the above diagram, class C is a subclass that has class A and class B as its parent. In a real-life scenario, a child inherits from their father and mother. This can be cons...
Variables are lvalues and so may appear on the left-hand side of an assignment. Numeric literals are rvalues and so may not be assigned and can not appear on the left-hand side. Following is a valid statement − But the following is not a valid statement and would generate compile-time...

Static- These variables holds their value between function calls. Example: #include <iostream.h> using namespace std; int main() { final int i=10; static int y=20; }
