All of the above.<\/p>\n<p>A programming language is said to be object-oriented if it supports the following features:<\/p>\n<ul>\n<li><strong>Encapsulation:<\/strong> The data and code that manipulates that data are kept together in a single unit called an object. This makes it easier to understand and maintain the code.<\/li>\n<li><strong>Inheritance:<\/strong> Objects can inherit the properties and methods of other objects. This makes it easier to reuse code and create new objects quickly.<\/li>\n<li><strong>Polymorphism:<\/strong> Objects can be used in different ways depending on their type. This makes code more flexible and reusable.<\/li>\n<\/ul>\n<p>Functions that return only a single value and #include files are not specific to object-oriented programming. They can be used in both object-oriented and non-object-oriented programming languages.<\/p>\n<p>Here is a brief explanation of each of the features of object-oriented programming:<\/p>\n<ul>\n<li><strong>Encapsulation:<\/strong> Encapsulation is the bundling of data and code together into a single unit called an object. This makes it easier to understand and maintain the code. For example, a car object might have data members for its speed, fuel level, and current gear. It might also have methods for accelerating, braking, and changing gears.<\/li>\n<li><strong>Inheritance:<\/strong> Inheritance is the ability of an object to inherit the properties and methods of another object. This makes it easier to reuse code and create new objects quickly. For example, a sports car object might inherit from a car object. This means that the sports car object would have all of the properties and methods of a car, plus any additional properties and methods that are specific to sports cars.<\/li>\n<li><strong>Polymorphism:<\/strong> Polymorphism is the ability of an object to be used in different ways depending on its type. This makes code more flexible and reusable. For example, a function that takes a car object as an argument might be able to accelerate the car, brake the car, or change the car&#8217;s gear. The specific action that the function takes will depend on the type of car that is passed to the function.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;functions that return only a single value&#8221; option2=&#8221;#include files&#8221; option3=&#8221;inheritance&#8221; option4=&#8221;All of the above&#8221; correct=&#8221;option4&#8243;]<\/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-19198","post","type-post","status-publish","format-standard","hentry","category-object-oriented-programming-using-c-plus-plus","no-featured-image-padding"],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.2 (Yoast SEO v23.3) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>To be called object-oriented, a programming language must allow A. functions that return only a single value B. #include files C. inheritance D.
