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++;
A: $count =+1;
B: ++ count;
C: count++;
D: $count++;
举一反三
- for(count = 1;sum=0; count <=10; count++)是正确的for语句
- 给定JSP程序源码如下: A: <%=++count%> B: <%++count;%> C: <%count++;%> D: <%=count++%>
- 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
- 写出下列程序的输出结果( )<?php $count =5; function get_count(){ static $count =0; return $count++;} echo $count; ++$count; echo get_count(); echo get_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
