What are arithmetic operators in Golang?

About Golang

Golang, also known as Go, is an open-source, compiled, and statically-typed programming language developed by Google. The language has a simple syntax and robust standard libraries.

It is used in real-world applications and supports imperative and OOP paradigms.

Operators

An operator is a symbol or function that indicates an operation. In Go, arithmetic operators perform just as they do in mathematics. They can be used as a calculator in Go.

Arithmetic operators

Here are some common arithmetic operators:

  • x+y: This provides the sum of two variables, x and y.

  • x-y: This provides the difference between x and y.

  • x*y: This provides the product of x and y.

  • x/y: This provides the quotient of x and y.

  • x%y: This provides the remainder of x and y after division.

  • x++: The value of x is increased by one.

  • x--: The value of x is decreased by one.

Example

package main
import (
	"fmt"
)
func main() {
	a := 10
  b := 8
	
  var sum = a + b
	fmt.Println(sum)
  var diff = a - b
	fmt.Println(diff)
  var product = a * b
	fmt.Println(product)
  var division = a/b
  fmt.Println(division)
 
  var module = a%b
  fmt.Println(module)
  a++
	fmt.Println(a)
	b--
	fmt.Println(b)
}

Explanation

  • Line 8: We assign the value, 10, to the variable a.
  • Line 9: We assign the value, 8, to the variable b.
  • Line 11: This is the syntax to add a and b.
  • Line 14: This is the syntax to subtract a and b.
  • Line 17: This is the syntax to multiply a and b.
  • Line 20: This is the syntax to divide a and b.
  • Line 23: This is the syntax to find the remainder of a and b.
  • Line 26: This is the value of a increased by one.
  • Line 29: This is the value of b decreased by one.
