What are some examples of operator precedence in programming?
Operator precedence determines the order in which operations are performed in expressions. For example, in the expression 3 + 4 * 5, the multiplication is performed first, resulting in 3 + 20, which equals 23.
Can you give me more examples with different operators?
Sure! In the expression 10 - 2 + 3, subtraction and addition have the same precedence, so we evaluate from left to right, resulting in 8 + 3 = 11.
What about parentheses? How do they affect precedence?
Parentheses have the highest precedence. For example, in (2 + 3) * 4, the addition is performed first, giving 5 * 4 = 20.
Are there any common mistakes to avoid with operator precedence?
Yes, a common mistake is assuming addition and subtraction are always evaluated from left to right without considering parentheses, which can lead to incorrect results.
