MyEclipse java注册码 生成代码
1.首先创建一个工程随便命名。
2.创建一个类命名为Reg.
3.执行代码
4.输入注册的姓名，显示栏目会出现please input register name:，只要输入英文名然后回车，注册码就出来了。把姓名和注册码像：
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
public class Reg {
private static final String LL = "Decompiling this copyrighted software is a violation of both your license agreement and the Digital Millenium Copyright Act of 1998 (http://www.loc.gov/copyright/legislation/dmca.pdf). Under section 1204 of the DMCA, penalties range up to a $500,000 fine or up to five years imprisonment for a first offense. Think about it; pay for a license, avoid prosecution, and feel better about yourself.";
public String getSerial(String userId, String licenseNum) {
java.util.Calendar cal = java.util.Calendar.getInstance();
cal.add(1, 3);
cal.add(6, -1);
java.text.NumberFormat nf = new java.text.DecimalFormat("000");
licenseNum = nf.format(Integer.valueOf(licenseNum));
String verTime = new StringBuilder("-").append(
new java.text.SimpleDateFormat("yyMMdd").format(cal.getTime()))
.append("0").toString();
String type = "YE3MP-";
String need = new StringBuilder(userId.substring(0, 1)).append(type)
.append("300").append(licenseNum).append(verTime).toString();
String dx = new StringBuilder(need).append(LL).append(userId)
.toString();
int suf = this.decode(dx);
String code = new StringBuilder(need).append(String.valueOf(suf))
.toString();
return this.change(code);
}
private int decode(String s) {
int i;
char[] ac;
int j;
int k;
i = 0;
ac = s.toCharArray();
j

一、
先看一个程序
#include <stdio.h>
int main()
{
const int a = 5;
int b[a];
return 0;
}
在vc6.0中命名为.c文件，编译会出错，是int b[a]这一行：expected constant expression
命名为.cpp文件，没问题。
在codeblocks(一个免费开源的编译器)中编译都� ......
