for(count = 1;sum=0; count <=10; count++)是正确的for语句
举一反三
- 将变量$count增1,下面哪种方式是正确的?( ) A: $count =+1; B: ++ count; C: count++; D: $count++;
- 下程序从终端读入数据到数组中,统计其中正数的个数,并计算它们之和。请填空。main(){ int i,a[20],sum,count;sum=count=0;for(i=0;i<20;i++) scanf("%d", ______);{ if(a[i]>0){ count++;sum+=______;}}printf("sum=%d,count=%d\n",sum,count);}
- 循环后count的值是什么? ( )int count = 0;do { System.out.println("Welcome to Java"); count++;} while (count A: 10 B: 11 C: 9 D: 8
- 给定一个Java程序的代码如下所示,则编译运行后,输出结果是 ( )。 public class Test { int count = 9; public void count() { System.out.println("count=" + count++); } A: blic static void main(String args[]) new Test().count(); new Test().count();}} B: count=9 count=9 C: count=10 count=9 D: count=10 count=10 E: count=9 count=10
- 下列程序打印( )次“Welcome to Java”?[br][/br] int count = 0; do { System.out.println("Welcome to Java"); count++; } while (count < 10);
