Summary
Section 10.1 Introduction
C++ enables you to overload most operators to be sensitive to the context in which they’re used— the compiler generates the appropriate code based on the types of the operands.
One example of an overloaded operator built into C++ is operator
<<
, which is used both as the stream insertion operator and as the bitwise left-shift operator. Similarly,>>
is also overloaded; it’s used both as the stream extraction operator and as the bitwise right-shift operator. Both of these operators are overloaded in the C++ Standard Library.C++ overloads

to perform differently, depending on their context in integer arithmetic, floating-point arithmetic and pointer arithmetic.The jobs performed by overloaded operators ...
