Features were added to programming languages so that parts of a program could control the access to their data. Scope refers to the visibility of variables and methods in one part of a program to another part of that program. The importance and meaning of scope varies between languages, but there are two general scope concepts many languages have in common: local and global scope.
Programming languages typically support a set of operators: constructs which behave generally like functions, but which differ syntactically or semantically from usual functions. Common simple examples include arithmetic, comparison, and logical operations. More involved examples include assignment, field access in a record or object, and the scope resolution operator. Languages usually define a set of built-in operators, and in some cases allow user-defined operators.
