界面如下图,请模拟计算器设计一个完成简单算术运算功能的计算器程序。 该程序应该具有下列功能:
(1)单击数字按钮输入运算量(在文本框显示)、选择运算符、单击等号按钮在文本框显示运算结果;(2)单击八进制数按钮,把文本框中显示的十进制数转换为八进制数显示在文本框中(...
(1) 单击数字按钮输入运算量(在文本框显示)、选择运算符、单击等号按钮在文本框显示运算结果;
(2) 单击八进制数按钮,把文本框中显示的十进制数转换为八进制数显示在文本框中(可使用Oct 函数);
(3) 单击十六进制数按钮,把文本框中显示的十进制数转换为十六进制数显示在文本框中(可使用Hex 函数);(4) 单击CE按钮,清除本次运算的所有选择(相关变量初始化),在文本框中显示0; 展开
(2) 单击八进制数按钮,把文本框中显示的十进制数转换为八进制数显示在文本框中(可使用Oct 函数);
(3) 单击十六进制数按钮,把文本框中显示的十进制数转换为十六进制数显示在文本框中(可使用Hex 函数);(4) 单击CE按钮,清除本次运算的所有选择(相关变量初始化),在文本框中显示0; 展开

不知道你要的是什么语言。我这地方也看不到图。
我这有个VBA版本的,不知道你要不要。要的话留下你的邮箱,我发给你;

你要进制转换的?
可以这样想
10进制转成二进制,除二取余,由最后向前排序就行了,其它进制就除相应的数(8进制8,16进制是16(10 用A,11B,12C,13D,14E,15F)
其它进制转换成10进制则可以用各位数值乘以基数(2,8,16)的n-次方(n为从右向左数的位数)的和就行。这说的是整数
小数还没见哪款计算器有
