What is operator precedence in programming?

What is operator precedence in programming?

Operator precedence determines the order in which operators are evaluated in expressions. It affects how calculations are performed.

Can you give me an example of operator precedence in an expression?

Sure! In the expression 3 + 4 * 5, the multiplication operator * has higher precedence than addition +, so it's evaluated first, resulting in 3 + 20 = 23.

What happens if I use parentheses?

Using parentheses changes the precedence. For example, in (3 + 4) * 5, the addition is evaluated first, resulting in 7 * 5 = 35.

Are there any common mistakes related to operator precedence?

Yes, a common mistake is assuming addition and multiplication have the same precedence, which can lead to incorrect results.
