Detailed Description

An expression in a C/C++ program.

In C/C++ an expression is a complicated beast that needs to be tamed to parse it correctly. An expression can be as simple as a word, e.g. x, 5 are valid expressions. It can be a function call. It can be an initialization list for an array or struct. e.g. POINT pt = {100, 500}; It can be a list of expressions used to call a function e.g. gcd(36, 42); new/delete statements are also expressions. It can be any of the arithmetic expression, e.g. a+b. To make things simple we treat a return statement as an expression.

structs CppExprAtom, and CppExpr are required to tame this difficult beast called expression in C/C++.
