Go语言嵌套if语句

在Go编程中嵌套if-else语句总是合法的,这意味着可以在另一个ifelse if语句中使用一个ifelse if语句。

语法

Go编程语言中嵌套if语句的语法是:

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

可以使用嵌套else if ... else类似的方式来嵌套if语句。

流程图

示例

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 );
}

当上述代码编译和执行时,它产生以下结果:

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