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if
或else if
语句中使用一个if
或else 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
