This article mainly explains "what is the basic knowledge of C # operator". The content of the explanation in this article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought. Let's study and learn what the basics of C # operators are.

Basic knowledge of C # operator 1. Arithmetic operator

Arithmetic operators include addition (+), subtraction (-), multiplication (*), division (/), and remainder (%). In addition to the addition and subtraction of integers and real numbers, the addition and subtraction operators also apply to enumerated types, string types, and delegate types, which are achieved through operator replanting.

String mf1= "Mike"; string mf2= "Cat"; string mf3=mf1+mf2;//mf3= "MikeCat" using System; enum Weekday {Sunday,Monday,Tuesday,Wednesday,Thursday,Friday,Saturday}; class MikeCat {static void Main () {Weekday mf1=Weekday.Sunday; Weekday mf2=mf1+3; Console.WriteLine ("mf1= {0}, mf2= {1}", mf1,mf2);}} / / result: mf1=Sunday,mf2=Wednesday

Basic knowledge of C # operator 2. Assignment operator

Assignment is to assign a new value to a variable. C # is divided into two categories: simple assignment and compound assignment.

Simple assignment: "=" a=b=c is equivalent to a = (breadc)

Compound assignment: "+ ="-= "* =" / = "% =" | = "^ =" = "axiomatic 10 is equivalent to a=a+10

Basic knowledge of C # operator 3. Comparison operator

The comparison operator is used to compare the size of two expressions, such as greater than (>).

Using System; class MikeCat {public static void Main () {int astat6; Console.WriteLine ("a = {0}", a); / 6 is 00000110; the binary of / 6 is 00000011, which is equal to 00000010 by bit and after, that is, 2 int bread6 | 3; Console.WriteLine ("b = {0}", b); / 6 is 00000110; the binary of / 6 is 00000011, which equals 00000111 by bit or later, that is, 7 int center6. Console.WriteLine ("c = {0}", c); the binary of / / 6 is 00000110, and the bitwise inverse is 11111001, that is,-7 int d = 6 ^ 3; Console.WriteLine ("d = {0}", d); / 6 is 00000110, and the binary of / 6 is 00000011, which is equal to 00000101 by XOR, that is, 5 int eigen62; Console.WriteLine ("f = {0}", f) The binary system of / / 6 is 00000110, and moving two digits to the right is equal to 00000001, that is, 1}} Thank you for your reading.
