Answer 3

#include<windows.h>

int main(){
    MessageBox(NULL,"正文1","标题1",0);
    MessageBox(NULL,"正文2","标题2",1);
    MessageBox(NULL,"正文3","标题3",2);
    MessageBox(NULL,"正文4","标题4",3);
    MessageBox(NULL,"正文5","标题5",4);
    //还可以有返回值，告诉你用户点击了哪个键
    if(MessageBox(NULL,"正文","标题",1)==1)
        MessageBox(NULL,"你点击了确定","判断返回值",0);
    else
        MessageBox(NULL,"你点击了取消","判断返回值",0);
    //一次只能运行一个MessageBox
}
