Operator classification and priority

OPERATOR:
I. mathematical operators:
+,-, *,/, ++ ,--

Example 1:

Example 2:

Example 3:

1. incremental Operators: ++
(1) Increment prefix Operator
Int x = 4;
X ++; // output result. The value of X is 5.

Example:

(2) Suffix incrementing Operator
Int x = 4;
+ + X; // output result. The value of X is 5.

Differences between prefix increment operators and suffix increment operators:
① Int y = ++ X;
Equivalent to X = x + 1;
Int y = X;
② Int y = x ++;
Equivalent to int y = X;
X = x + 1;
2. Decrease Operator:--
Incremental operators.

Example:

2. Relational operators, 6 in total. Only true or false is returned.
= ,! =, <,>, <=,> =

Example:

3. logical operators.
& (And) | (OR )! (Not)

Example:

Iv. assignment operators
=, + =,-=, * =, % =,/=

Example:

5. Conditional operators ()? ():()
Example: x = (x> 12 )? (X-12) :( X );
// If x> 12, then x = x-12, otherwise x = x.
