Go - Relational Operators


Advertisements

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

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

package main

import "fmt"

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

   if( a == b ) {
      fmt.Printf("Line 1 - a is equal to b\n" )
   } else {
      fmt.Printf("Line 1 - a is not equal to b\n" )
   }
   if ( a < b ) {
      fmt.Printf("Line 2 - a is less than b\n" )
   } else {
      fmt.Printf("Line 2 - a is not less than b\n" )
   } 
   if ( a > b ) {
      fmt.Printf("Line 3 - a is greater than b\n" )
   } else {
      fmt.Printf("Line 3 - a is not greater than b\n" )
   }
   
   /* Lets change value of a and b */
   a = 5
   b = 20
   if ( a <= b ) {
      fmt.Printf("Line 4 - a is either less than or equal to  b\n" )
   }
   if ( b >= a ) {
      fmt.Printf("Line 5 - b is either greater than  or equal to b\n" )
   }
}

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

Line 1 - a is not equal to b
Line 2 - a is not less than b
Line 3 - a is greater than b
Line 4 - a is either less than or equal to  b
Line 5 - b is either greater than  or equal to b
