# #514 – Examples of Operator Precedence

February 7, 2012 Leave a comment

Each operator has an associated precedence, which indicates the order in which the operators are evaluated when evaluating the expression.

For example, because multiplicative (*, /, %) operators have a higher precedence than additive (+, -) operators, the multiplication in the expression below happens before the addition, so the answer is 34.

int result = 4 + 5 * 6;

If we want the addition to happen first, we can change the precedence by using parentheses.

// Result = 54 int result = (4 + 5) * 6;

Here are some other examples of operator precedence.

// Negation operator has higher precedence than conditional operators bool res = !false || true; // true (negation operator evaluated first) res = !(false || true); // false (conditional OR evaluated first) // && has higher precedence than || bool res = true || false && false; // true res = (true || false) && false; // false
