Go - Assignment Operators
The following table lists all the assignment operators supported by Go language −
| Operator | Description | Example |
|---|---|---|
| = | Simple assignment operator, Assigns values from right side operands to left side operand | C = A + B will assign value of A + B into C |
| += | Add AND assignment operator, It adds right operand to the left operand and assign the result to left operand | C += A is equivalent to C = C + A |
| -= | Subtract AND assignment operator, It subtracts right operand from the left operand and assign the result to left operand | C -= A is equivalent to C = C - A |
| *= | Multiply AND assignment operator, It multiplies right operand with the left operand and assign the result to left operand | C *= A is equivalent to C = C * A |
| /= | Divide AND assignment operator, It divides left operand with the right operand and assign the result to left operand | C /= A is equivalent to C = C / A |
| %= | Modulus AND assignment operator, It takes modulus using two operands and assign the result to left operand | C %= A is equivalent to C = C % A |
| <<= | Left shift AND assignment operator | C <<= 2 is same as C = C << 2 |
| >>= | Right shift AND assignment operator | C >>= 2 is same as C = C >> 2 |
| &= | Bitwise AND assignment operator | C &= 2 is same as C = C & 2 |
| ^= | bitwise exclusive OR and assignment operator | C ^= 2 is same as C = C ^ 2 |
| |= | bitwise inclusive OR and assignment operator | C |= 2 is same as C = C | 2 |
Example
Try the following example to understand all the assignment operators available in Go programming language −
package main
import "fmt"
func main() {
var a int = 21
var c int
c = a
fmt.Printf("Line 1 - = Operator Example, Value of c = %d\n", c )
c += a
fmt.Printf("Line 2 - += Operator Example, Value of c = %d\n", c )
c -= a
fmt.Printf("Line 3 - -= Operator Example, Value of c = %d\n", c )
c *= a
fmt.Printf("Line 4 - *= Operator Example, Value of c = %d\n", c )
c /= a
fmt.Printf("Line 5 - /= Operator Example, Value of c = %d\n", c )
c = 200;
c <<= 2
fmt.Printf("Line 6 - <<= Operator Example, Value of c = %d\n", c )
c >>= 2
fmt.Printf("Line 7 - >>= Operator Example, Value of c = %d\n", c )
c &= 2
fmt.Printf("Line 8 - &= Operator Example, Value of c = %d\n", c )
c ^= 2
fmt.Printf("Line 9 - ^= Operator Example, Value of c = %d\n", c )
c |= 2
fmt.Printf("Line 10 - |= Operator Example, Value of c = %d\n", c )
}
When you compile and execute the above program it produces the following result −
Line 1 - = Operator Example, Value of c = 21 Line 2 - += Operator Example, Value of c = 42 Line 3 - -= Operator Example, Value of c = 21 Line 4 - *= Operator Example, Value of c = 441 Line 5 - /= Operator Example, Value of c = 21 Line 6 - <<= Operator Example, Value of c = 800 Line 7 - >>= Operator Example, Value of c = 200 Line 8 - &= Operator Example, Value of c = 0 Line 9 - ^= Operator Example, Value of c = 2 Line 10 - |= Operator Example, Value of c = 2
