对于程序员来说，新建一个cpp文件是再频繁不过的事情了。
为了方便，我们习惯在桌面右键新建文件，而不是新建一个文本文档，然后修改后缀名。
百度谷歌查询了一下，终于知道如何添加注册表。
手痒，抽出时间用cpp写了一个程序，方便以后操作。
客户需求是永远无法满足的，经同学测试，陆续写了三个版本。
接下来直接贴代码~
第一个版本，只能添加c、cpp、java三种后缀。

#include <cstdio>
#include <cmath>
#include <ctime>
#include <cctype>
#include <cstring>
#include <cstdlib>
#include <climits>
#include <cfloat>
#include <iostream>
#include <vector>
#include <stack>
#include <queue>
#include <set>
#include <map>
#include <algorithm>
using namespace std;
char s[1024], buffer[128], result[1024*4];
void work_1() {
system("reg add \"HKEY_CLASSES_ROOT\\.c\\ShellNew\" /v \"NullFile\" /t REG_SZ");
}
void work_2() {
system("reg add \"HKEY_CLASSES_ROOT\\.cpp\\ShellNew\" /v \"NullFile\" /t REG_SZ");
}
void work_3() {
system("reg add \"HKEY_CLASSES_ROOT\\.java\\ShellNew\" /v \"NullFile\" /t REG_SZ");
}
int main() {
printf("Add registry for C, C++ and Java\n");
printf("Author: Haipz\nSchool: HDU\n");
printf("1 for C;\n2 for C++;\n3 for Java.\n");
printf("Example: 12 to add C and C++.\n");
printf("Please make choice(s): ");
gets(s);
for (int i = 0; s[i] != '\0'; ++i) {
printf("Working...\n");
if (s[i] == '1') work_1();
else if (s[i] == '2') work_2();
else if (s[i] == '3') work_3();
else printf("%c is a wrong enter!\n", s[i]);
}
system("pause");
return 0;
}
第二个版本，精简了代码，支持添加用户输入的后缀。
/*

* School: HDU
* File Name: registry2.0.cpp
*/
#include <cstdio>
#include <cmath>
#include <ctime>
#include <cctype>
#include <cstring>
#include <cstdlib>
#include <climits>
#include <cfloat>
#include <iostream>
#include <vector>
#include <stack>
#include <queue>
#include <set>
#include <map>
#include <algorithm>
using namespace std;
char a[1024];
char b[1024] = "reg add \"HKEY_CLASSES_ROOT\\.";
char c[1024] = "\\ShellNew\" /v \"NullFile\" /t REG_SZ";
void work(char* a) {
strcat(b, a);
strcat(b, c);
system(b);
}
int main() {
printf("Function: Add registry to build a new file simply!\n");
printf("Author: Haipz\nSchool: HDU\n");
printf("Example: Enter c to add C and enter cpp to add C++.\n");
printf("Your opion: ");
gets(a);
work(a);
system("pause");
return 0;
}
第三个版本，支持多次添加，并允许删除已添加的注册表。

gets(a);
if (a[0] == '-') del(a + 1);
else add(a);
printf("Enter \"r\" to run again or any other key to quit: ");
gets(key);
} while (key[0] == 'r');
return 0;
}
