Take a look at Cinder. It's a C++ library designed for 'creative coding' and looks pretty simple to use while still being powerful (check the examples).
You could also try SFML. It has quite a following and you'll have a large community behind you should you have any trouble.
If you are looking for "modern" and "not much boilerplate" why not JavaScript? It will run directly in the browser and you can either use a <canvas> element or bundle up a setPixel DOM function in a script you supply to your students.
If you are committed to C++, there is always OpenGL but there is, I suppose a bit more of a learning curve. In the old days there was BGI, and GRX for DJGPP (anyone remember that?). I don't know of many device-independent libraries for writing pixels to the screen (GDI and Xlib are too OS-specific). In the Perl/Python/Tcl world there is Tk, which is O.S. independent.
Personally I like JavaScript for low-level graphics algorithms -- no setup! -- but if you are not tied to C++ it might be worth a look. But if you don't have time to teach JavaScript then perhaps some of your students can implement some algorithms for extra credit.
SDL 是您最好的选择。我无法让 Graphics.h 与 Dev C++ 一起使用，因为较新版本的 Windows 与它不兼容。如果您只想绘制窗口和 UI 内容，另一个可能有效的图形库是 GLFW。
SDL is your best bet. I could not get graphics.h to work with Dev C++ as newer versions of Windows are incompatible with it. Another graphics library that might work is GLFW, if all you want is to draw windows and UI stuff.

Allegro 或 SDL 库可能适合您。
我还建议不要使用 Bloodshed Dev-C++，因为它也有点过时了。您可以使用 MS VC++ Express 或Code::Blocks 两者都是免费的。
Allegro or SDL libraries may be for you.
I would also suggest not to use Bloodshed Dev-C++ as it is also a little outdated. You may use MS VC++ Express or Code::Blocks which are both free.
看看 Cinder。它是一个专为“创意编码”而设计的 C++ 库，看起来使用起来非常简单，但仍然很强大（查看示例）。
您也可以尝试 SFML。它拥有相当多的追随者，如果您遇到任何麻烦，您将有一个庞大的社区为您提供支持。

如果您正在寻找“现代”和“没有太多样板”，为什么不是 JavaScript 呢？它将直接在浏览器中运行，您可以使用
元素，也可以在提供给学生的脚本中捆绑setPixelDOM 函数。您可以查看以下链接： http://www.codeproject.com/KB/脚本/javascriptlinedrawing.aspx。
还有一个问题：Javascript 中的 Bresenham 算法。
如果您致力于 C++，那么总会有 OpenGL，但我认为学习曲线要长一些。过去有 BGI 和 DJGPP 的 GRX（还有人记得那个吗？）。我不知道有多少独立于设备的库用于将像素写入屏幕（GDI 和 Xlib 太特定于操作系统）。在 Perl/Python/Tcl 世界中，有 Tk，它与操作系统无关。
就我个人而言，我喜欢使用 JavaScript 来实现低级图形算法——无需设置！ -- 但如果您不依赖 C++，那么它可能值得一看。但如果你没有时间教授 JavaScript，那么也许你的一些学生可以实现一些算法来获得额外的学分。

And a SO question: Bresenham algorithm in Javascript.

该库与 BGI（Borland Graphics Interface） API 兼容，这意味着它使用“ Graphics.h") 用于 Visual Studio。

this library is API compatible with BGI(Borland Graphics Interface, which means it uses "graphics.h") for Visual Studio.
