推荐答案
创建一个临时缓冲区来您的字符串存储和使用的sprintf
,根据您的变量更改格式类型。对于你的第一个例子以下应该工作:
Create a temporary buffer to store your string in and use sprintf
, change the formatting depending on your variable type. For your first example the following should work:
char buff[100];
string name = "stackoverflow";
sprintf_s(buff, "name is:%s", name.c_str());
cout << buff;
然后调用消息框的buff作为字符串参数
Then call message box with buff as the string argument
MessageBox(hWnd, buff, "Msg title", MB_OK | MB_ICONQUESTION);
有一个int更改为:
int d = 3;
sprintf_s(buff, "name is:%d",d);
