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。

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。
/*

#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。
