此程序能运行出结果，但结果不能保存，求助！！！
非常感谢啊！！！

你可以将图形数据存至外存上.
然后,通过算法把外存上的数据换化为图形数据回放到屏幕上就可以了.
----------------解决方案--------------------------------------------------------
多谢高手赐教啊，不过你说的我还是不会整 啊！！！
有没有最简单的办法啊？
多谢拉！！！

最简单应该是这个了.

最好自己定义一个读写图形文件的格式(结构体之类的),用哪方法存的再用它取
----------------解决方案--------------------------------------------------------
用fopen fwrite 保存好你的数据
char *v[]={"0.0","0.1","0.2","0.3","0.4","0.5","0.6","0.7","0.8","0.9","1.0"};
char *dmax[]={"25","24","23","22","21","20","19","18","17","16","15"};
float JL[]={18.75,18.43,17.70,20.75,18.73,20.62,21.81,21.01,20.27,18.47,15.66};
float CT[]={18.64,18.34,17.61,20.62,18.62,20.47,21.65,20.87,20.16,18.38,15.58};
下次用 fopen fread 调用这些数据进行画图
