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。

/* * Author: Haipz * School: HDU * File Name: registry1.0.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 s[1024], buffer[128], result[1024*4]; void work_1() { system("reg add "HKEY_CLASSES_ROOT.cShellNew" /v "NullFile" /t REG_SZ"); } void work_2() { system("reg add "HKEY_CLASSES_ROOT.cppShellNew" /v "NullFile" /t REG_SZ"); } void work_3() { system("reg add "HKEY_CLASSES_ROOT.javaShellNew" /v "NullFile" /t REG_SZ"); } int main() { printf("Add registry for C, C++ and Javan"); printf("Author: HaipznSchool: HDUn"); 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] != ''; ++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。

/* * Author: Haipz * 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: HaipznSchool: HDUn"); 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。

/* * Author: Haipz * 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 key[1024]; char a[1024]; void add(char* t) { char b[1024] = "reg add "HKEY_CLASSES_ROOT."; char c[1024] = "ShellNew" /v "NullFile" /t REG_SZ"; strcat(b, t); strcat(b, c); system(b); } void del(char* t) { char d[1024] = "reg delete "HKEY_CLASSES_ROOT."; char e[1024] = "ShellNew" /f"; strcat(d, t); strcat(d, e); system(d); } int main() { printf("Function: Build a new file simply!n"); printf("Author: HaipznSchool: HDUn"); printf("Example: Enter "c" to add C and enter "cpp" to add C++;n"); printf(" Enter "-c" to delete C.n"); do { printf("Your opion: "); 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; }
