what arithmetic operators

[Note] C # basic introduction -- Arithmetic Operators of C, Add: +.The plus sign has two purposes: When the plus sign is used to connect two numbers, the sum of the two numbers is calculated. For example: Console. WriteLine (9 + 2.2); // output 11.2

This section to talk about arithmetic operators1. Automatic conversion of the result type.Package Com.ray.ch01;public class Test {public static void main (string[] args) {int a = 2, b = 3;int c = A/b;int D = b/ A System.out.println (c);

One. Describes other types of operators.In addition to the +,-,*,/,%,+ connector described earlier, there are two + +,--。Two. + + self-incrementDefinition: Add one on the basis of the original data and assign it to the original data.The

I. Re-understanding of the self-increment operatorThe first thing to understand is that operators are symbolic representations of operations, and each of these operators represents a specific operation. The forms of these operations are various, and

I. Overview operatorsSome of the previous explanations are errors, in constants and variables that piece, around the ground is to assign constants to the variable, here is talking about the operation, the previous is not considered an operation. The

First lists all the arithmetic operatorsStep Two:Precautions:When we use arithmetic operators, remember that the following things are important:1. The addition operator should be aware that when connecting strings, it is only possible to add strings

IntroducedArithmetic operators are used in mathematical expressions, and they function in the same way as they do in mathematics. The following table lists all the arithmetic operators.The instance in the table assumes that the value of integer

Typically, the "/" arithmetic operator is calculated based on the data on either side of the participating operation, such as:6/3 = 2; 6,3 are integers, then the result is an integer 2;6.0/3.0 = 2.0; 6.0,3.0 is a floating-point number, then the

[Switch] C ++ Operator Overloading guidelines Http://www.cs.caltech.edu/courses/cs11/material/cpp/donnie/cpp-ops.html   One of the nice features of C ++ is that you can give special meanings to operators, when they are used with user-defined

If the data type is the brick of the programming language, the operators and operators are the lime and cement of the programming language. It is a mixture of values of various data types, so that the data value is no longer just an isolated value,
