[amp_mcq option1=”additional data members” option2=”additional member functions” option3=”both (a) and (b)” option4=”neither (a) nor (b)” correct=”option3″]<\/p>\n
The correct answer is C. both (a) and (b).<\/p>\n
When a class inherits from another class, it gains access to all of the data members and member functions of the base class. It can also add its own data members and member functions. This means that an inherited class can have more data members and member functions than the base class.<\/p>\n
For example, consider the following code:<\/p>\n
“`class Base {
\npublic:
\n int x;
\n void foo() {
\n cout << “Base::foo()” << endl;
\n }
\n};<\/p>\n
class Derived : public Base {
\npublic:
\n int y;
\n void bar() {
\n cout << “Derived::bar()” << endl;
\n }
\n};
\n“`<\/p>\n
The class In conclusion, inherited classes may have additional data members and member functions compared with the classes from which they are derived.<\/p>\n","protected":false},"excerpt":{"rendered":" [amp_mcq option1=”additional data members” option2=”additional member functions” option3=”both (a) and (b)” option4=”neither (a) nor (b)” correct=”option3″]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[683],"tags":[],"class_list":["post-56063","post","type-post","status-publish","format-standard","hentry","category-object-oriented-programming-using-c-plus-plus","no-featured-image-padding"],"yoast_head":"\nDerived<\/code> inherits from the class Base<\/code>.
