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。
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 "); 39 printf("Author: Haipz School: HDU "); 40 printf("1 for C; 2 for C++; 3 for Java. "); 41 printf("Example: 12 to add C and C++. "); 42 printf("Please make choice(s): "); 43 gets(s); 44 for (int i = 0; s[i] != ' '; ++i) { 45 printf("Working... "); 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! ", s[i]); 50 } 51 system("pause"); 52 return 0; 53 }
第二个版本，精简了代码，支持添加用户输入的后缀。
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! "); 35 printf("Author: Haipz School: HDU "); 36 printf("Example: Enter c to add C and enter cpp to add C++. "); 37 printf("Your opion: "); 38 gets(a); 39 work(a); 40 system("pause"); 41 return 0; 42 }
第三个版本，支持多次添加，并允许删除已添加的注册表。

"); 44 printf("Author: Haipz School: HDU "); 45 printf("Example: Enter "c" to add C and enter "cpp" to add C++; "); 46 printf(" Enter "-c" to delete C. "); 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 }
