Go - Relational Operators

Quiz

The following table lists all the relational operators supported by Go language. Assume variable A holds 10 and variable B holds 20, then −

Operator	Description	Example
==	It checks if the values of two operands are equal or not; if yes, the condition becomes true.	(A == B) is not true.
!=	It checks if the values of two operands are equal or not; if the values are not equal, then the condition becomes true.	(A != B) is true.
>	It checks if the value of left operand is greater than the value of right operand; if yes, the condition becomes true.	(A > B) is not true.
<	It checks if the value of left operand is less than the value of the right operand; if yes, the condition becomes true.	(A < B) is true.
>=	It checks if the value of the left operand is greater than or equal to the value of the right operand; if yes, the condition becomes true.	(A >= B) is not true.
<=	It checks if the value of left operand is less than or equal to the value of right operand; if yes, the condition becomes true.	(A <= B) is true.

Example - Usage of Equality Operators

Try the following example to understand equality operators available in Go programming language −

main.go

package main

import "fmt"

func main() {
   var a int = 21
   var b int = 10

   if( a == b ) {
      fmt.Printf("a is equal to b\n" )
   } else {
      fmt.Printf("a is not equal to b\n" )
   }
   
   /* Lets change value of a and b */
   a = 5
   b = 20
   if ( a <= b ) {
      fmt.Printf("a is either less than or equal to  b\n" )
   }
   if ( b >= a ) {
      fmt.Printf("b is either greater than or equal to b\n" )
   }
}

Output

When you compile and execute the above program it produces the following result −

a is not equal to b
a is either less than or equal to  b
b is either greater than or equal to b

Example - Usage of < and & gt; Operators

Try the following example to understand < and & gt; operators available in Go programming language −

main.go

package main

import "fmt"

func main() {
   var a int = 21
   var b int = 10

   if ( a < b ) {
      fmt.Printf("a is less than b\n" )
   } else {
      fmt.Printf("a is not less than b\n" )
   } 
   if ( a > b ) {
      fmt.Printf("a is greater than b\n" )
   } else {
      fmt.Printf("a is not greater than b\n" )
   }
}

Output

When you compile and execute the above program it produces the following result −

a is not less than b
a is greater than b
