阅读下面程序
A: result="";
B: result=null
C: result=number1
D: result=number2
A: result="";
B: result=null
C: result=number1
D: result=number2
举一反三
- 以下代码的运行结果为 def calculate(number): result = 0 i = 1 while i <= number: result = result + i i += 1 return result result = calculate(100) print('1~100的累积和为:', result)
- 以下程序执行完后,c与result的值是:()。 A: c:false;result:1; B: c:true;result:2; C: c:true;result:1; D: c:false;result:2;
- 下面程序段的输出结果是( )。 public class Test public static void main ( String[] args) int result=0; for ( int i=1;i<=5;i++) if ( i%2==0 ) continue; result + =i; System. out. println ("result is " + result ); A: result is 7 B: result is 8 C: result is 9 D: result is 10
- 以下代码执行的结果是:( )int i=2;int result = 0;switch (i) {case 1:result = result + i;case 2:result = result + i * 2;case 3:result = result + i * 3;}System.out.println(result); A: 0 B: 2 C: 4 D: 10
- 下面的方法,当输入为2的时候返回值是多少?( ) public static int getValue(int i) { int result = 0; switch (i) { case 1: result = result + i; case 2: result = result + i * 2; case 3: result = result + i * 3; } return result; }
