Operator precedence defines the order in
which an expression evaluates when several different operators are present. C
and C++ have specific rules to determine the order of evaluation. The easiest to

subtraction. After that, if an expression isn’t transparent to you it
probably won’t be for anyone reading the code, so you should use
parentheses to make the order of evaluation explicit. For
example:
