Operators in GO

• Operators are used to perform operations on variables and values.
• Operators allow operands to be combined into expressions
• Operators are either binary operators or unary operators. A binary operator operation takes two operands and a unary operator operation takes only one operand.

Arithmetic Operators

• Go supports the following arithmetic operators.
  

• To demonstrate the use of arithmetic operators; create new folder as 03-01 ArithmeticOperators in src folder of the workspace and create arithmetic_op.go file and type the following code.
  

• Following is the output of above example.

• Commit and push changes to GitHub.

$ git add .
$ git commit -m "03-01 ArithmeticOperators"
$ git push origin master

Assignment Operators

• Assignment operators are used to assign values to variables.
• Following is the list of assignment operators.

• Create 03-02 AssignmentOperators folder in src folder and add a file assignment_op.go and type the following example.
  

• Following is the output of above example.
  

• Commit changes to GitHub
  

$ git add .
$ git commit -m "03-02 AssignmentOperators"
$ git push origin master

Comparison/Relational Operators

• Comparison operators are used to compare two values.

• Following is the list of comparison operators.
  

• The following example demonstrates the usage of comparison operators. Create folder 03-03 ComparisonOperators in src folder and file with the name comparison_op.go
  

• Following is the output.
  

• Commit changes to GitHub.
  

$ git add .
$ git commit -m "03-03 ComparisonOperators"
$ git push origin master

Logical Operators

• Logical operators are used for operations on Boolean values within the logical expressions.

• Following is the list of logical operators supported by Go.
  

• Let’s create a folder 03-04 LogicalOperators in src folder of your workspace and then create file logical_op.go
  

• On execution the following output will be shown.
  

• Commit changes to GitHub.
  

$ git add .
$ git commit -m "03-04 LogicalOperators"
$ git push origin master

Bitwise Operators

• Bitwise operators work on bits and perform bit-by-bit operation.
• Following is the list of bitwise operators supported by Go.
• To demonstrate the usage of bitwise operators create folder 03-05 BitwiseOperators and file bitwise_op.go

• Following is the output.
  

• Finally commit Changes to GitHub.
  

$ git add .
$ git commit -m "03-05 BitwiseOperators"
$ git push origin master

Operators Precedence

• Operator precedence determines the grouping of terms in an expression.
• This affects how an expression is evaluated.
• The following table lists Go's operator precedence level, starting with the highest.
