What is operator precedence in programming?

What is operator precedence in programming?

Operator precedence determines the order in which operators are evaluated in expressions. For example, in the expression 3 + 4 * 5, the multiplication is performed first due to higher precedence.

Can you give me an example with parentheses?

Sure! In the expression (3 + 4) * 5, the addition inside the parentheses is evaluated first, resulting in 7, and then multiplied by 5 to give 35.

How does this differ in different programming languages?

While most languages follow similar precedence rules, there can be differences. For instance, Python and JavaScript have the same precedence for basic operators, but some languages may have unique rules for specific operators.

What happens if I don't use parentheses?

If you don't use parentheses, the expression will be evaluated based on the operator precedence rules, which might lead to unexpected results if you're not aware of them.

Where can I find a complete list of operator precedence?

You can find a complete list of operator precedence in the documentation of the specific programming language you're using, or on websites like MDN for JavaScript.
