Operator _ and _ operator priority

Mathematical operators (7 ):

+,-, *,/, %, ++, And ,--

1 · % is the remainder operator, for example: 3% 2 = 1 8% 3 = 2

2. ++ and -- are the auto-increment 1 and auto-increment 1 operators.

3. I ++ and I both add 1 operations. For example, I ++ and ++ I are equal to I = I + 1 (I = I ++ and I = ++ I have different meanings than I ++ and I + I, (it can be understood that the plus sign first adds the 1 operation and then the value assignment, and the plus sign first adds the value to the 1 operation. For example, int I = 6; I = ++ I; the result is 7, I = I ++; the result is 6 .))

 

Relational operators:

= ,! =, <,>, <=,> =

 

Logical operators (common and boolean operators ):

& (Logical and), | (logical or ),! (Non-logical)

&: True only when all conditions are met.

|: True if one condition is met.

! : The highest level in logical operators.

 

Conditional OPERATOR :? :

Int I;

String S = (relational operation )? (1) :( 2 );

(If the conditions are met, output within 1 bracket; if the conditions are not met, output within 2 brackets)

! : The highest level in logical operators.

 

Computing priority example

Int I = 5;

Int S = int. parse (console. Readline (); // The keyboard accepts integer S.

Bool B =! (S> 5) & (S> = (1 + 2*3-(I ++ )));

Bool B =! (S> 5) & (S> = (1 + 2*3-(-- I )));
Bool B =! (S> 5) & amp; S> = 1 + 2*3--- I;

Bool B =! (S> 5) & amp; S> = 1 + 2*3-(-- I)/2;
