Theory of programming

QuestionAnswer
What is the difference between coercion, polymorphism and overloading Overloading- a name having more than one object at any point in a program. Coercion-when a compiler converts one type into value of another when required by surrounding context. Polymorphism allows a single subroutine to accept argument of multiple types.
What is difference between declaration and definition? Declaration introduces name and indicates scope. Definition describes object in detail for compiler to determine implementation.
What do we mean by scope of a name to object binding? the scope of a name to object binding refers to the area of a program that the name of the object doesn't change.
What is difference between static and dynamic scoping? Static scoping is defined by the syntax of the program and dynamic scoping relies on the current state of program execution.
