What are the operators in Go language?

In programming languages, operators are symbols used by programmers to perform arithmetic and logical operations. In the Go language, there are many kinds of operators, including arithmetic operators, comparison operators, logical operators, bitwise operators, etc. This article will introduce operators in Go language in detail.

1. Arithmetic operators

The arithmetic operators in Go language are used to perform common arithmetic operations, including addition, subtraction, multiplication, division, remainder, increment and decrement, etc. The following is a list of arithmetic operators in Go language:

• Plus sign, used to add two numbers
• Minus sign, used to subtract one number from another number
• Multiply sign, used to multiply two numbers
  / Division sign, used to divide one number by another number
  % Remainder sign, used to get the division of two numbers The remainder after
  is the auto-increment operator, used to increase the value of a variable by 1
  -- the auto-decrement operator, used to reduce the value of a variable by 1

2. Comparison operators

Comparison operators in Go language are used to compare the size relationship between two variables, and the result returns a Boolean value. The following is a list of comparison operators in the Go language:

== The equal sign is used to compare whether the values ​​​​of two variables are equal
!= The inequality sign is used to compare whether the values ​​​​of two variables are not equal.

Greater than sign, used to compare whether one variable is greater than another variable
< Less than sign, used to compare whether one variable is less than another variable
= Greater than or equal to sign, used to compare a variable Whether it is greater than or equal to another variable
<= The less than or equal sign is used to compare whether a variable is less than or equal to another variable

3. Logical operators

Go language Logical operators are used to perform logical operations such as AND, OR, NOT, etc. The following is a list of logical operators in the Go language:

&& The AND operator is used to determine whether two conditions are true at the same time
|| The OR operator is used to determine whether one of the two conditions is true One is true
! Non-operator, used to negate the value of a condition (if the condition is true, return false; if the condition is false, return true)

4. Bitwise operator

In computer systems, numbers are represented in binary form. Bitwise operators are symbols used to manipulate binary numbers. In Go language, there are many kinds of bitwise operators. The following is a list of bitwise operators in Go language:

& bitwise AND symbol, used to get the intersection of two numbers (compares every bit of each number, if the two numbers are in the same If the positions are all 1, return 1; otherwise return 0)
| Bitwise or sign, used to obtain the union of two numbers (compares every bit of each number, if the two numbers are in the same If the positions are all 0, return 0; otherwise return 1)
^ Bitwise XOR symbol, used to obtain different bits in two numbers (compare each bit of each number, if the two numbers are in If the same positions are the same, 0 is returned; otherwise 1 is returned)
<< Left shift symbol, used to move all bits of a number to the left by the specified number of digits

right The shift symbol is used to shift all the bits of a number to the right by the specified number of digits

Summary

This article introduces common operators in the Go language, including arithmetic operators, Comparison operators, logical operators and bitwise operators. Operators are an important part of the Go language and they help programmers perform important arithmetic and logical operations. Proficiency with these operators is important for writing efficient and correct code.
