### Expressions and Operators

Expressions are sequences of operators, operands, and punctuators that specify a computation. The evaluation of an expressions is based on the operators that the expression contains, and the context in which the operators are used.

C++ operators can be defined to behave differently when applied to operands of class type. This is called operator overloading. The C language does not permit overloading.
