Golang Assignment Operators

Assignment operators are used for assigning the expressions or values to the variable/ constant etc. These operators assign the result of the right-side expression to the left-side variable or constant. The "=" is an assignment operator. Assignment operators can also be the combinations of some other operators (+, -, *, /, %, etc.) and "=". Such operators are known as compound assignment operators.

List of Golang Assignment Operators

Operator	Description	Example x:=5 y:=3
Assignment (=)	It assigns the result of the expression written on the right side to the variable written on the left side.	x = 10 or x = y+10 or x = x+5, etc.
Add and Assignment (+=)	It is the combination of '+' and '=' operators, it adds the given value with the current value of the variable and assigns it to the variable.	x +=y is equivalent to x = x+y
Subtract and Assignment (-=)	It is the combination of '-' and '=' operators, it subtracts the given value with the current value of the variable and assigns it to the variable.	x -=y is equivalent to x = x-y
Multiply and Assignment (*=)	It is the combination of '*' and '=' operators, it multiplies the given value with the current value of the variable and assigns it to the variable.	x *=y is equivalent to x = x*y
Divide and Assignment (/=)	It is the combination of '/' and '=' operators, it divides the given value with the current value of the variable and assigns it to the variable.	x /=y is equivalent to x = x/y
Modulus and Assignment (%=)	It is the combination of '%' and '=' operators, it finds the remainder of the current value of the variable with the given value and assigns it to the variable.	x %=y is equivalent to x = x%y
Bitwise AND Assignment (&=)	It is the combination of '&' and '=' operators, it performs the Bitwise AND operation with the current value of the variable and the given value and assigns the result to the variable.	x &=y is equivalent to x = x&y
Bitwise OR Assignment (|=)	It is the combination of '|' and '=' operators, it performs the Bitwise OR operation with the current value of the variable and the given value and assigns the result to the variable.	x |=y is equivalent to x = x|y
Bitwise XOR Assignment (^=)	It is the combination of '^' and '=' operators, it performs the Bitwise XOR operation with the current value of the variable and the given value and assigns the result to the variable.	x ^=y is equivalent to x = x^y
Bitwise Left Shift Assignment (<<=)	It is the combination of '<<' and '=' operators, it performs the Bitwise Left-shift operation with the current value of the variable and the given value and assigns the result to the variable.	x <<=y is equivalent to x = x<<y
Bitwise Right Shift Assignment (>>=)	It is the combination of '>>' and '=' operators, it performs the Bitwise Left-shift operation with the current value of the variable and the given value and assigns the result to the variable.	x >>=y is equivalent to x = x>>y

Example of Golang Assignment Operators

The below Golang program is demonstrating the example of assignment operators.

// Golang program demonstrate the
// example of assignment operators

package main

import "fmt"

func main() {
	x := 5
	y := 3

	x += y
	fmt.Println("x:", x)

	x -= y
	fmt.Println("x:", x)

	x *= y
	fmt.Println("x:", x)

	x /= y
	fmt.Println("x:", x)

	x %= y
	fmt.Println("x:", x)

	x &= y
	fmt.Println("x:", x)

	x |= y
	fmt.Println("x:", x)

	x <<= y
	fmt.Println("x:", x)

	x >>= y
	fmt.Println("x:", x)
}

Output:

x: 8
x: 5
x: 15
x: 5
x: 2
x: 2
x: 3
x: 24
x: 3
