Operators
Logical operators in programming are like a set of tools that help us decide what to do depending on how things look. Logical operators tell the computer to do something based on how two different things compare.

-
Addition Arithmetic Operators
-
The addition operator returns the sum of two variables.
Go
Example of addition operator in go.
package main

import "fmt"

func main() {
	var age int = 20

	fmt.Println(age + 1) // 21
}

-
-
-
Subtraction Arithmetic Operators
-
The subtraction operator returns the difference of two variables.
Go
Example of subtraction operator in go.
package main

import "fmt"

func main() {
	var age int = 20

	fmt.Println(age - 2) // 18
}

-
-
-
Multiplication Arithmetic Operators
-
The multiplication operator returns the product of two variables.
Go
Example of multiplication operator in go.
package main

import "fmt"

func main() {
	var age int = 20

	fmt.Println(age * 3) // 60
}

-
-
-
Division Arithmetic Operators
-
The division operator returns the quotient of two variables.
Go
Example of division operator in go.
package main

import "fmt"

func main() {
	var age int = 20

	fmt.Println(age / 2) // 10
}

-
-
-
Modulus Arithmetic Operators
-
The modulus operator returns the remainder of two variables.
Go
Example of modulus operator in go.
package main

import "fmt"

func main() {
	var age int = 20

	fmt.Println(age % 9) // 2
}

-
-
-
Exponentiation Arithmetic Operators
-
The exponentiation operator returns the power of two variables.
Go
Example of exponentiation operator in go.
package main

import (
	"fmt"
	"math"
)

func main() {
	var age float64 = 2

	fmt.Println(math.Pow(age, 3)) // 8
}

-
-
-
Equal Comparison Operators
-
The equal operator checks if two variables are equal value.
Go
Example of equal operator in go.
package main

import "fmt"

func main() {
	var age int = 20

	fmt.Println(age == 20) // true
}

-
-
-
Equal Type Comparison Operators
-
The equal type operator checks if two variables are equal value and type.
Go
Example of equal type operator in go.
package main

import "fmt"

func main() {
	var age string = "20"

	fmt.Println(age == "20") // true
}

-
-
-
Not Equal Comparison Operators
-
The not-equal operator checks if two variables are not equal value.
Go
Example of not-equal operator in go.
package main

import "fmt"

func main() {
	var age int = 20

	fmt.Println(age != 18) // true
}

-
-
-
Not Equal Type Comparison Operators
-
The not-equal type operator checks if two variables are not equal value and type.
Go
Example of not-equal type operator in go.
// NA
-
-
-
Greater Than Comparison Operators
-
The greater-than operator checks if the value of the first variable is greater than the second.
Go
Example of greater-than operator in go.
package main

import "fmt"

func main() {
	var age int = 20

	fmt.Println(age > 18) // true
}

-
-
-
Less Than Comparison Operators
-
The less-than operator checks if the value of the first variable is less than the second.
Go
Example of less-than operator in go.
package main

import "fmt"

func main() {
	var age int = 20

	fmt.Println(age < 21) // true
}

-
-
-
Greater Than or Equal Comparison Operators
-
The greater-than or equal-to operator checks if the value of the first variable is greater than or equal to the second.
Go
Example of greater-than or equal-to operator in go.
package main

import "fmt"

func main() {
	var age int = 20

	fmt.Println(age >= 20) // true
}

-
-
-
Less Than or Equal Comparison Operators
-
The less-than or equal-to operator checks if the value of the first variable is less than or equal to the second.
Go
Example of less-than or equal-to operator in go.
package main

import "fmt"

func main() {
	var age int = 20

	fmt.Println(age <= 20) // true
}
