Method overloading is used to achieve compile time polymorphism. it is difficult to generate machine code for each OS. A late binding. Method overriding says the child class has the same method as . can't decide whether to call parent class method or child class method, it's jvm which makes the decision. Compile-time polymorphism is the use of templates (instances of which's types vary, but are fixed at compile time) whereas run-time polymorphism refers to the use of inheritance and virtual functions (instances of which's types vary and are fixed at run time). Compiler does choose which version of the class to instantiate based on the type T we provide, so does this mean class templates also exibit compile time polymorphic behaviour ? For example, at compile time you determine the actual type of a std::vector by what it contains: I'm not sure why you think it it is limited to functions. I will cover topics like Spring boot, Angular, SQL and so on. And how is it going to affect C++ programming? Compile-time polymorphism is a polymorphism that is resolved during the compilation process. It indicates that method overriding occurs when a child class offers a custom implementation of a method offered by another of its parent classes. Answer: Polymorphism that is resolved during compiler time is known as static polymorphism or compile time polymorphism. Why is processing a sorted array faster than processing an unsorted array?
