Operator precedencedetermines which operator is evaluated first when an expression has more than one operators. For example 100-2*30 would yield 40, because it is evaluated as 100 – (2*30) and not (100-2)*30. The reason is that multiplication * has higher precedence than subtraction(-)....

The standard itself doesn't specify precedence levels. They are derived from the grammar. In C++, the conditional operator has the same precedence as assignment operators, and prefix ++ and -- and assignment operators don't have the restrictions about their operands. ...

Operator Precedence: When an expression has more than one operator, C has to determine the order in which to execute them. This is called the "precedence." Precedence of some basic operators: ++, --,!, (unary -), (unary +)// increment, decremement, not, unary ops ...
