What is operator precedence in coding?

What is operator precedence in coding?

Operator precedence determines the order in which different 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 a real-world example of operator precedence?

Sure! In a budgeting application, if you calculate total expenses with a formula like total = rent + utilities * tax_rate, the multiplication of utilities and tax_rate will be calculated first before adding rent.

What happens if I change the order of operations?

If you change the order by adding parentheses, like total = (rent + utilities) * tax_rate, it will yield a different result because now the addition is performed before the multiplication.

Are there any common mistakes related to operator precedence?

Yes, a common mistake is forgetting to use parentheses when needed, which can lead to unexpected results in calculations.
