C++里面怎么实现打开CMD运行一条命令？

C++里面怎么实现运行CMD.exe
然后CMD里面在运行一条命令？

Answer 1

#include <windows.h>

代码中写
SYSTEM(" <指令>");

引号里面是字符串，所以很简单的吧？
写个死循环，接收字符串，放到这里来就好了

while(true){
char str[256]={0};
scanf("%s",str)
SYSTEM(str);
}

Answer 2

可以使用int system(const char *command)函数
来调用DOS命令
*command指的是DOS命令
调用成功则返回0，否则返回-1
例如system("dir");

Answer 3

void CDlgtest4Dlg::OnButton9()
{
// TODO: Add your control notification handler code here
SHELLEXECUTEINFO ShExecInfo = {0};
ShExecInfo.cbSize = sizeof(SHELLEXECUTEINFO);
ShExecInfo.fMask = SEE_MASK_NOCLOSEPROCESS;
ShExecInfo.hwnd = NULL;
ShExecInfo.lpVerb = NULL;
ShExecInfo.lpFile = "cmd.exe";
ShExecInfo.lpParameters = _T("/k dir");
ShExecInfo.lpDirectory = _T("");
ShExecInfo.nShow = SW_SHOW;
ShExecInfo.hInstApp = NULL;

ShellExecuteEx(&ShExecInfo);

}
你可以执行cmd /?查看CMD的参数
