Go - 嵌套 if 语句


在 Go 编程中嵌套if-else 语句始终是合法的,这意味着您可以在另一个 if 或 else if 语句中使用一个 if 或 else if 语句。

句法

嵌套 if语句的语法如下 -

if( boolean_expression 1) {
   /* Executes when the boolean expression 1 is true */
   if(boolean_expression 2) {
      /* Executes when the boolean expression 2 is true */
   }
}

您可以以与嵌套if语句类似的方式嵌套else if...else

例子

package main

import "fmt"

func main() {
   /* local variable definition */
   var a int = 100
   var b int = 200
 
   /* check the boolean condition */
   if( a == 100 ) {
      /* if condition is true then check the following */
      if( b == 200 )  {
         /* if condition is true then print the following */
         fmt.Printf("Value of a is 100 and b is 200\n" );
      }
   }
   fmt.Printf("Exact value of a is : %d\n", a );
   fmt.Printf("Exact value of b is : %d\n", b );
}

当上面的代码被编译并执行时,它会产生以下结果 -

Value of a is 100 and b is 200
Exact value of a is : 100
Exact value of b is : 200
