Which operator has the lowest precedence?

Question

BlackTom AI · Accepted Answer

To determine which operator has the lowest precedence, I will compare the typical precedence levels of each option.

Option 1: '!=' — This is a comparison operator. In many languages, comparisons (like !=, ==, <, >) have higher precedence than logical operators but lower than arithmetic and exponentiation. Since it sits above logical 'and' in precedence, it is not the lowest among the options.

Option 2: '*' — The multiplication operator. Arithmetic operators like '*' generally have a higher precedence than comparison and logical operators. This means '*' executes before any '!=' or 'and' in expressions, so it is not the lowest.

Option 3: '**' — The exponentiation operator. Typically the highest among the listed due to its role in raising numbers to powers. In almost all languages that include '**' (or an equivalent), it binds more tightly than multiplication and certainly more tightly than comparisons or logical operators. Therefore, '**' is not the lowest.

Option 4: 'and' — This is a logical conjunction. Logical operators like and/or have lower precedence than most arithmetic and comparison operators. Among the given options, 'and' is the one that binds least tightly, making it the lowest precedence.

Putting the pieces together, the operator with the lowest precedence among the options is the logical 'and' operator, since it is evaluated after the arithmetic and comparison operations in expressions. This reflects the general precedence ladder where arithmetic > comparison > logical (and/or).
