下面程序段的输出结果是( )。 public class Test public static void main (String[] args) int n=10,result=0; for (int i=1;i<=n;i++) result+=i; System.out.println("result is"+result);
A: A) result is 55
B: B) result is 45
C: C) result is 56
D: D) result is 54
A: A) result is 55
B: B) result is 45
C: C) result is 56
D: D) result is 54
举一反三
- 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
- 写出下面程序的输出( )。 public class Test { public static void main (String args[ ]) { iht x=1, y=2; System. out. println ("result="+x+y); System. out. println ("result="+(x+y)); A.result=12 result=12 B.result=3 result=3 C.result=3 result=12 D.result=12 result=3
- 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
- 下面程序的运行结果是( )。 #include<iostream.h> int fun(int a[],int n) int result=1; for(int i=1;i<n;i++) result=result *a[i]; return result; void main() int a[3]=3,4,5; eout<<fun(a,3)<<end1;[/i] A: 12 B: 15 C: 20 D: 60
- 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; }
