Operations and operators in C language and operators in C Language
1. Operator priority and associativity 1. Priority

In the operator list, the higher the operator, the higher the priority.

 

2. associativity

If O is used to represent binary operators that require two operands, then the expression aObOc:

The left Union operator interprets the expression as (aOb) Oc [left Union]

The right Union operator interprets the expression as aO (bOc) [right Union]

Conclusion: When an operator with the same priority is encountered, the combination indicates whether the expression should be operated from left to right or from right to left.
