The answer is not Rather, the answer which will surprise many is , assuming 32 bit integers. So when the two operands are, as in our example, 25u unsigned int and 50 int , the 50 is promoted to also being an unsigned integer i. Moreover, the result of the operation will be of the type of the operands. Therefore, the result of 25u - 50u will itself be an unsigned integer as well. So the result of converts to when promoted to being an unsigned integer. Give an example.

The imperative, object-oriented programming language is widely used as a general-purpose programming language. The full form of OOPS is an Object-Oriented Programming System, which means a paradigm that provides an application of various concepts, including data binding, polymorphism, inheritance, and various others. Answer: Class is referred to as the designing of the user-defined data type. It reflects the different entities, attributes, and actions. Answer: Object is an instance of the class. An object can have fields, methods, constructors, and related. For example, a bike in real life is an object, but it has various features such as brakes, color, size, design, and others, which are instances of its class.

Try to give examples when you answer this question. Class defines a datatype, it's type definition of category of thing s. But a class actually does not define the data, it just specifies the structure of data. To use them you need to create objects out of the class. Class can be considered as a blueprint of a building, you can not stay inside blueprint of building, you need to construct building s out of that plan. You can create any number of buildings from the blueprint, similarly you can create any number of objects from a class.
