Q:-What is Function Overloading ?A:-Function overloading: C++ enables several functions of the same name to be defined, as long asthese functions have different sets of parameters (at least as far as their types are concerned). Thiscapability is called function overloading. When an overloaded function is called, the C++ compilerselects the proper function...

Q:-What is namespace?A:-Namespaces allow us to group a set of global classes, objects and/or functions under a name. To sayit somehow, they serve to split the global scope in sub-scopes knownas namespaces.The form to use namespaces is:namespace identifier { namespace-body }Where identifier is any valid identifier and namespace-body is the set of classes,...
1. What is virtual constructors/destructors?Virtual destructors: If an object (with a non-virtual destructor) is destroyed explicitly by applyingthe delete operator to a base-class pointer to the object, the base-class destructor function(matching the pointer type) is called on the object.There is a simple solution to this problem – declare a virtual...
