此代码取自http://msdn.microsoft.com/en-us/library/system.console.windowwidth.aspx 我想用gcc编译器编译它。
#include<cstdio>
#include<string>
#include<windows.h>
#include<iostream>
using namespace System;
int main()
{
int origWidth;
int width;
int origHeight;
int height;
String^ m1 = "The current window width is {0}, and the "
"current window height is {1}.";
String^ m2 = "The new window width is {0}, and the new "
"window height is {1}.";
String^ m4 = " (Press any key to continue...)";
//
// Step 1: Get the current window dimensions.
//
origWidth = Console::WindowWidth;
origHeight = Console::WindowHeight;
Console::WriteLine( m1, Console::WindowWidth, Console::WindowHeight );
Console::WriteLine( m4 );
Console::ReadKey( true );
//
// Step 2: Cut the window to 1/4 its original size.
//
width = origWidth / 2;
height = origHeight / 2;
Console::SetWindowSize( width, height );
Console::WriteLine( m2, Console::WindowWidth, Console::WindowHeight );
Console::WriteLine( m4 );
Console::ReadKey( true );
//
// Step 3: Restore the window to its original size.
//
Console::SetWindowSize( origWidth, origHeight );
Console::WriteLine( m1, Console::WindowWidth, Console::WindowHeight );
}
但它显示错误。
错误是

我需要在代码中添加什么?
答案 0 :(得分:6)
该代码不是C ++,而是C++/CLI。使用Microsoft编译器。
答案 1 :(得分:2)
Console
是一个.NET类,只能由C ++ / CLI访问。
Regular C ++不使用.NET框架,也无法访问其中的类。
所以你需要决定你正在写哪种语言。
