D編程 nested if statements
2021-09-01 11:23 更新
在D編程中，嵌套if-else語(yǔ)句意味著您可以在另一個(gè)if或else if語(yǔ)句中使用一個(gè)if或else if語(yǔ)句。
nested if - 語(yǔ)法
嵌套if語(yǔ)句的語(yǔ)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 */
}
}nested if - 示例
import std.stdio;
int main () {
/* local variable definition */
int a=100;
int b=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 */
writefln("Value of a is 100 and b is 200" );
}
}
writefln("Exact value of a is : %d", a );
writefln("Exact value of b is : %d", b );
return 0;
}編譯并執(zhí)行上述代碼時(shí)，將生成以下結(jié)果-
Value of a is 100 and b is 200
Exact value of a is : 100
Exact value of b is : 200 以上內(nèi)容是否對(duì)您有幫助：
