What is the difference between operator precedence and associativity in coding?

What is the difference between operator precedence and associativity in coding?

Operator precedence determines the order in which operators are evaluated in an expression, while associativity defines the direction of evaluation for operators of the same precedence.

Can you give me an example of how they work together?

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

What happens if I change the order of operations?

If you want to change the order, you can use parentheses. For example, (3 + 4) * 5 will evaluate to 7 * 5, which equals 35.

Are there any languages where this works differently?

Most programming languages follow similar rules for operator precedence and associativity, but it's always good to check the specific language documentation for any exceptions.
