• 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
}
