C ++ uses the Registry to add a desktop right-click to create a menu, and the Registry Desktop

For programmers, it is no longer frequent to create a cpp file.

For convenience, we are used to right-click the desktop to create a file, instead of creating a text document, and then modify the suffix.

Baidu Google looked up and finally learned how to add a registry.

It takes time to write a program with cpp to facilitate subsequent operations.

Customer requirements cannot be met forever. After testing, three versions are successively written.

Next, paste the Code directly ~

In the first version, only three suffixes c, cpp, and java can be added.

 1 /* 2  * Author: Haipz 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 }

The second version simplifies the code and supports adding suffixes entered by users.

 1 /* 2  * Author: Haipz 3  * School: HDU 4  * File Name: registry2.0.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 a[1024];24 char b[1024] = "reg add \"HKEY_CLASSES_ROOT\\.";25 char c[1024] = "\\ShellNew\" /v \"NullFile\" /t REG_SZ";26 27 void work(char* a) {28     strcat(b, a);29     strcat(b, c);30     system(b);31 }32 33 int main() {34     printf("Function: Add registry to build a new file simply!\n");35     printf("Author: Haipz\nSchool: HDU\n");36     printf("Example: Enter c to add C and enter cpp to add C++.\n");37     printf("Your opion: ");38     gets(a);39     work(a);40     system("pause");41     return 0;42 }

In the third version, you can add the Registry multiple times and delete it.

 1 /* 2  * Author: Haipz 3  * School: HDU 4  * File Name: registry2.0.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 key[1024];24 char a[1024];25 26 void add(char* t) {27     char b[1024] = "reg add \"HKEY_CLASSES_ROOT\\.";28     char c[1024] = "\\ShellNew\" /v \"NullFile\" /t REG_SZ";29     strcat(b, t);30     strcat(b, c);31     system(b);32 }33 34 void del(char* t) {35     char d[1024] = "reg delete \"HKEY_CLASSES_ROOT\\.";36     char e[1024] = "\\ShellNew\" /f";37     strcat(d, t);38     strcat(d, e);39     system(d);40 }41 42 int main() {43     printf("Function: Build a new file simply!\n");44     printf("Author: Haipz\nSchool: HDU\n");45     printf("Example: Enter \"c\" to add C and enter \"cpp\" to add C++;\n");46     printf("         Enter \"-c\" to delete C.\n");47     do {48         printf("Your opion: ");49         gets(a);50         if (a[0] == '-') del(a + 1);51         else add(a);52         printf("Enter \"r\" to run again or any other key to quit: ");53         gets(key);54     } while (key[0] == 'r');55     return 0;56 }
