Go語言嵌套if語句
Go語言程序中嵌套if-else語句它始終是合法的,這意味著你可以使用一個if else在另一份if 或else if 語句聲明中。
語法
嵌套if語句的語法如下:
if( boolean_expression 1) { /* Executes when the boolean expression 1 is true */ if(boolean_expression 2) { /* Executes when the boolean expression 2 is true */ } }
您可以嵌套else if ...else在類似if語句的方式。
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 ); }
讓我們編譯和運行上麵的程序,這將產生以下結果:
Value of a is 100 and b is 200 Exact value of a is : 100 Exact value of b is : 200
