求大神帮助检查错误，小白解决不了了，，，

ERbbit 2017-09-07 06:17:53
我按照书上的程序敲了一个图轮廓线的设计的程序，但是书上给的是一段升程的，我设计的是三段，如下图滚子位移曲线所示。我对书上程序有一些改动，为了能够运行也改了很多地方。我使用的是VS2017，一些所需库什么的百度也都安了，但是程序运行后却不能得到正常图像，我对C语言的了解几乎为零，求各位帮助，谢谢啦下面是效果图，类似

http://www.easyx.cn 代码功能归根结底不是别人帮自己看或讲解或注释出来的；而是被自己静下心来花足够长的时间和精力亲自动手单步或设断点或对执行到某步获得的中间结果显示或写到日志文件中一步一步分析出来的。 提醒：再牛×的老师也无法代替学生自己领悟和上厕所！ 单步调试和设断点调试（VS IDE中编译连接通过以后，按F10或F11键单步执行，按Shift+F11退出当前函数；在某行按F9设断点后按F5执行停在该断点处。）是程序员必须掌握的技能之一。

编译没错，可以运行 ，就说明语法没问题，就是公式写错了~~
