Expressions and operators

Lecture 1 - Slide 25 : 34

Expressions and operators in C are well-known

Similar to the means of expression in most other languages in C family

Expressions are evaluated to obtain a value
Expressions in C may have side effects
- Assignments are expressions
- Other dirty operators: ++, -- (both prefix and postfix)
Operators
- In C: A fixed repertoire with fixed meanings
- In C++: A fixed repertoire, but overloadable

C++ adds three new operators ( .*, ->*, ::) of which the scope operator :: is the most important

( .* and ->* are special operators that binds pointer to members to a particular object)
