2.20. Go language if statement nesting

You can do it in the if or else if statement to embed one or more if or else if statement.

2.20.1. Grammar #

In programming Go language the syntax of the if...else statement is as follows:

If Boolean expression 1 {
   /* Execute when Boolean expression 1 is true */
   If Boolean expression 2 {
      /* Execute when Boolean expression 2 is true */
   }
}

You can nest else if...else statements within the if statement in the same way

2.20.2. Example #

Nested use if Statement:

Example #

package main
import "fmt"
func main() {
   /* Define local variables */
   var a int = 100
   var b int = 200

   /* Judging conditions */
   if a == 100 {
       /* Execute if the conditional statement is true */
       if b == 200 {
          /* Execute if the conditional statement is true */
          fmt.Printf("The value of a is 100, and the value of b is 200\\n" );
       }
   }
   fmt.Printf("The value of a is : %d\\n", a );
   fmt.Printf("The value of b is: %d\\n", b );
}

The result of the above code execution is:

The value of a is 100, and the value of b is 200
The value of a is: 100
The value of b is: 200
