Operator types (four classes)

One, arithmetic operators:

a:++--B: */% c: +-

Note: 1. When doing a division, if two numbers are integers, the result is an integer, not a decimal.

2. The above operations, if the two operands are not a type, will be automatically converted at the time of operation

3. Order of operations: first operation a type, then B type, and finally C type (the following operators operate in the same order)

Use of surplus (%):

1. Can be used to determine whether an integer, the remainder is 0 o'clock, is an integer

2. A number used to turn a number into a range

Operations of a++ and ++a

a++: int a=4 b=a++

Console.WriteLine ("A=" +a);

Console.WriteLine ("b=" +b); Result: a=5,b=4 executes b=a, then executes a++ (i.e. a=a+1) when the operation is performed

++a:int a=4 B=++a

Console.WriteLine ("A=" +a);

Console.WriteLine ("b=" +b); Result: A=5,b=5 performs ++a (that is, a=a+1) when the operation is performed, and then executes B=a

Example one:

Example Two

two, relational operators : A. > < >= <= B. == !=

logic operator :a.&& logic and b. | | Logical OR C.! Logical Non-

iv. assignment operator := + = = *=/= * /
