The purpose of this article is to share with you what the operator with the lowest priority is. The editor thinks it is very practical, so I hope you can learn something after reading this article. Let's take a look at it with the editor.
The lowest precedence operator is the comma operator. The order in which expressions are combined depends on the priority of the various operators in the expression; the operators with high priority are combined first, and the operators with low priority are combined later, and the operators on the same line have the same priority.
The lowest precedence operator is the comma operator.
An expression may include several data objects with different data types connected by different operators; because the expression has a variety of operations, different combination sequences may result in different results or even erroneous operations. because when an expression contains a variety of operations, it must be combined in a certain order in order to ensure the rationality of the operation and the correctness and uniqueness of the results.
The priority decreases from top to bottom, with the highest priority at the top and the lowest priority for the comma operator. The order in which expressions are combined depends on the priority of the various operators in the expression. Operators with high priority are combined first, and operators with low priority are combined later, and operators on the same line have the same priority.
Knowledge expansion
Priority
Priority is independent of the order in which it is evaluated. For example, although * has the highest priority, the expression is evaluated from left to right, for example, axib & & bailc.
The priority decreases from top to bottom, with the highest priority at the top and the lowest priority for the comma operator.
In the same priority, the combination is carried out according to the combination. Most operators are associative from left to right, and only three precedence are combined from right to left. They are unary operators, conditional operators, and assignment operators.
The basic priorities need to be remembered:
The pointer is the best, and monocular operation is better than binocular operation. Such as a plus or minus sign.
First the arithmetic operation, then the shift operation, and finally the bit operation. Please pay special attention to: 1
