c計算器源碼
㈠ win7自帶計算器的源代碼
win7在運行處 輸入calc.exe，可以直接進如計算器！
㈡ c++計算器源代碼
#include<iostream>//簡單的計算器
using namespace std;//DEV c++
int main()
{
int a,b;
char c;//這里變數名只能為char
cout<<"計算器"<<endl;
cout<<"你想使用哪種計算器(+,-,*,/)"<<endl;
cin>>c;
switch(c)//這里是對+，-，*，/進行使用（c）
{
case '+'://加法運算
{
cout<<"請輸入第一個數"<<endl;
cin>>a;
cout<<"請輸入第二個數"<<endl;
cin>>b;
cout<<a<<"+"<<b<<"="<<a+b;
}
break;//break是終止
case '-'://減法運算
{
cout<<"請輸入第一個數"<<endl;
cin>>a;
cout<<"請輸入第二個數"<<endl;
cin>>b;
cout<<a<<"-"<<b<<"="<<a-b;
}
break;
case '*'://乘法運算
{
cout<<"請輸入第一個數"<<endl;
cin>>a;
cout<<"請輸入第二個數"<<endl;
cin>>b;
cout<<a<<"*"<<b<<"="<<a*b;
}
break;
case '/'://除法運算
{
cout<<"請輸入第一個數"<<endl;
cin>>a;
cout<<"請輸入第二個數"<<endl;
cin>>b;
if(b!=0)
{
cout<<a<<"/"<<b<<"="<<a/b;
}
else cout<<"除數不能為0"<<endl;
}
break;
default:cout<<"請輸入正確的運算符號"<<endl;//特殊情況
}
return 0;
}
㈢ 如何查看電腦上某程序的源代碼 如計算器
可以通過GitHub源代碼ping在計算機中檢查計算器的源代碼。具體操作方式如下：
1、進入GitHub的Microsoft個人問題主頁，如下圖所示。
(3)c計算器源碼擴展閱讀：
GitHub的Windows應用
GitHub 使用 git 分布式版本控制系統，而 git 最初是 LinusTorvalds 為幫助Linux開發而創造的，它針對的是 Linux 平台，因此 git 和 Windows 從來不是最好的朋友，因為它一點也不像Windows。
GitHub 發布了GitHub for Windows，為 Windows 平台開發者提供了一個易於使用的 Git 圖形客戶端。
GitHub forWindows是一個 Metro 風格應用程序，集成了自包含版本的 Git，bash 命令行 shell，PowerShell 的 posh-git 擴展。
GitHub 為 Windows 用戶提供了一個基本的圖形前端去處理大部分常用版本控制任務，可以創建版本庫，向本地版本庫遞交補丁，在本地和遠程版本庫之間同步。微軟也通過CodePlex向開發者提供 git 版本控制系統，而 GitHub 創造了一個更具有吸引力的 Windows 版本。
㈣ 求C++編寫的科學計算器源代碼
給你個地址，自己去下載。
★★[源碼庫]811款導彈-制導-彈道-慣性導航-GPS-雷達等模擬源代碼★★
http://bbs.81tech.com/read.php?tid=209564
其中有兩款計算機源代碼：
1. 科學計算器程序--VC++源代碼.rar (30 K)
2. 非常實用的一款計算器-VC++源代碼.rar (138 K)
㈤ 關於java做的計算器源代碼
關於計算器的設計其實是一個很大的學問，如果你按照嚴格的設計來完成一個計算器的話，完成之後。你就是一個很牛的人了。注意我說的是很牛
關於這方面的資料我建議你看本書
《大話設計模式》
這本書就是從計算器來展開的設計模式的運用和講解
㈥ c語言計算器程序源代碼
棧操作~
輸入的弄成字元串。
如：a+(b+c*(d+e))
先檢索「（」入棧，b入棧，+入棧，c入棧，*入棧，後面的不是數字那麼「（」入棧，+，入棧，e入棧，
「）」入棧，遇到「）」，出棧操作，直到遇到第一個「（」。
得到字元：d+e,通過演算法計算出值D,然後把D入棧。那麼棧中的字元為：a+(b+c*D
向後判斷一步看是不是乘或除，不是繼續向後入棧，是就出棧。
得到c*D，通過演算法計算值為C，入棧，那麼棧中的字元為：a+(b+C，向後判斷，無乘或除運算，繼續入棧：「）」，遇到「）」，出棧操作，直到遇到第一個「（」，得到字元串：b+c，演算法計算值為B，入棧
棧中字元串為：a+B 字元串結束，出棧操作計算出a+B,值。
如果字元串的式子很長的話，就反復的入棧出棧計算。
思路是這樣的......
關於COS，SIN類的關鍵字，也是上面的思路，
(入棧，直到遇到)出棧，先計算出括弧里的，然後後退一步判斷前面的是乘除或者關鍵字，
如：sin(0.1+0.2)
操作得出sin0.3然後判斷前面的是不是關鍵字，是那句計算sin0.3。
但是遇到關鍵字的時候不是一個一個字元在一起的，你可以入棧的時候判斷是不是字母，是字母，那麼入棧直到不是字母為止，出棧判斷關鍵字也是一樣......
不明白的繼續問~
㈦ C#計算器源代碼
全部按鈕的事件代碼可以省略成1個方法
private void Btn_click(object sender, EventArgs e)
{
//(button)sender，把sender參數強制轉換成按鈕類型，根據按鈕的文本屬性判斷是哪個按鈕
string buttonType= ((button)sender).Text;
}
