[求助]HAPPY教授，还要麻烦你帮帮我

bryan

<P>我是学C的，所以我的程序可能有时候潜意识按照C的规则来写，还要指正了。我下面的程序要做的是，实现A矩阵通过图形界面进行输入，我是想通过一个子函数调用来画出输入矩阵的框图，可是总也画不出来。我想问的问题如下：<BR>1。我想通过用户自己输入阶次来画出矩阵，我是保存在Z里面，不知道后面子函数调用的时候，Z是不是里面有了输入的数据？我这些写程序合适?<BR>2。有没有合适的函数，不用挨个画每个矩阵元素的输入框，只要告诉阶次就可以开辟面积输入?如果没有的话，我这样做，咋总是不能实现我的画矩阵元素输入框功能呢？<BR>3。子函数括号里面需要标出所有用到的变量吗？<BR><BR>我在很努力的看书，但还是解决不了，请您帮看看啊。如果您比较忙，给我指出问题，我自己调试也可以。麻烦了。<BR><BR>clf reset</P>
