齿轮程序重新修正!!

crane_QS

经过meflying大哥指点,我已把程序改正了!!~~



有兴趣的朋友可以试一下了





       

meflying

tcc和tee返回的都是字符串,为什么还要用itoa?,而且你后面的计算应该使用数字才对,应该用atoi吧

crane_QS

是的!! 谢谢大哥!!



我已经改正了,现在可以正确的运行了!~

我不会编程.请问一下大哥.你写的这个东西加载以后输什么命令呀.........才能用

cag

齿形怎么会是直线呢？

yuncai11

本来想遍个齿轮的程序的，看来有人捷足先登了呵呵


对了是不是3D的啊？？？

llccadd

我真的不知道，这个应该怎么用，能说明白一点吗？
