So far, you have learned about arithmetic operators, +, -,
*, /, and %, the output operator, <<, and the
assignment operator, =. In general, an operator is a
symbol, or combination of symbols, that is treated by the compiler in a
special way.
Most operators are special in that they receive arguments via flanking
operands, rather than via the parenthesized argument lists used by ordinary
functions. Some operators, such as the new operator, which you
learn about in the hardcopy version of this book, and the delete operator, which you
learn about in the hardcopy version of this book are special in that they do not evaluate
their arguments. Still others, such as the conditional operator, which you
learn about in the hardcopy version of this book, are special in that they evaluate some
arguments, but not others.
