可执行文件的自我删除（笔试题）

Write a program delete itself after execution.
思路：调用cmd命令来删除,用ShellExecute来执行cmd命令
#include <ShlObj.h>
#include <shellapi.h>
#include <string.h>
int main(int argc, char* argv[])
{
 char str[100];
 GetModuleFileName(NULL,str,100);
 char str1[100]="/c del ";
 strcat(str1,str);
 ShellExecute(NULL, "open","cmd.exe", str1,NULL, SW_HIDE);
 return 0;
}
