Go 嵌套的if语句
在Go编程中,使用一个if语句或者else if语句嵌套另一个if语句或者else if语句是合法的。这意味着你可以在一个if语句或者else if语句中使用另一个if语句或者else if语句。
语法
嵌套的if语句的语法如下所示:
if( boolean_expression 1) {
/* Executes when the boolean expression 1 is true */
if(boolean_expression 2) {
/* Executes when the boolean expression 2 is true */
}
}
你可以以类似的方式嵌套 else if…else ,就像你嵌套if语句一样。
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 );
}
当上述代码被编译并执行时,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
