對於程序員來說，新建一個cpp文件是再頻繁不過的事情了。
為了方便，我們習慣在桌面右鍵新建文件，而不是新建一個文本文檔，然後修改後綴名。
百度谷歌查詢了一下，終於知道如何添加注冊表。
手癢，抽出時間用cpp寫了一個程序，方便以後操作。
客戶需求是永遠無法滿足的，經同學測試，陸續寫了三個版本。
接下來直接貼代碼~
第一個版本，只能添加c、cpp、java三種後綴。
1 /*

3 * School: HDU
4 * File Name: registry1.0.cpp
5 */
6 #include <cstdio>
7 #include <cmath>
8 #include <ctime>
9 #include <cctype>
10 #include <cstring>
11 #include <cstdlib>
12 #include <climits>
13 #include <cfloat>
14 #include <iostream>
15 #include <vector>
16 #include <stack>
17 #include <queue>
18 #include <set>
19 #include <map>
20 #include <algorithm>
21 using namespace std;
22
23 char s[1024], buffer[128], result[1024*4];
24
25 void work_1() {
26 system("reg add \"HKEY_CLASSES_ROOT\\.c\\ShellNew\" /v \"NullFile\" /t REG_SZ");
27 }
28
29 void work_2() {
30 system("reg add \"HKEY_CLASSES_ROOT\\.cpp\\ShellNew\" /v \"NullFile\" /t REG_SZ");
31 }
32
33 void work_3() {
34 system("reg add \"HKEY_CLASSES_ROOT\\.java\\ShellNew\" /v \"NullFile\" /t REG_SZ");
35 }
36
37 int main() {
38 printf("Add registry for C, C++ and Java\n");
39 printf("Author: Haipz\nSchool: HDU\n");
40 printf("1 for C;\n2 for C++;\n3 for Java.\n");
41 printf("Example: 12 to add C and C++.\n");
42 printf("Please make choice(s): ");
43 gets(s);
44 for (int i = 0; s[i] != '\0'; ++i) {
45 printf("Working...\n");
46 if (s[i] == '1') work_1();
47 else if (s[i] == '2') work_2();
48 else if (s[i] == '3') work_3();
49 else printf("%c is a wrong enter!\n", s[i]);
50 }
51 system("pause");
52 return 0;
53 }
第二個版本，精簡了代碼，支持添加用戶輸入的後綴。

37 printf("Your opion: ");
38 gets(a);
39 work(a);
40 system("pause");
41 return 0;
42 }
第三個版本，支持多次添加，並允許刪除已添加的注冊表。
