超详细一、因为计算器设计的控件太多，不便使用控制台应用程序完成，所以这里使用Windows窗体应用程序，并命名为Calc,如下图所示：二、向窗体中拖入需要的控件，如下图所示：（完成效果图）结果显示区（作者博客左边的文本框）是TextBox控件，并修改其name为txtShow ，按键0~9为Button控件，并将其name分别修改为btn_0、btn_1、btn_2、btn_3、btn_4、btn_5、btn_6、btn_7、btn_8、btn_9；按键【负数】的name值修改为btn_sign，按键【.】的name 修改为btn_dot，按键【+ - * /】的name值分别修改为btn_add、btn_sub、btn_mul、btn_div，按键【=】的name值修改为btn_equ，按键【倒数】的name值修改为btn_rev，按键【平方】的name值修改为btn_sqr，按键【开方】的name值修改为btn_sqrt。

右边的计算器图片空间是PictureBox，作者博客控件是LinkLabel，可以不添加，以上所有控件均可按照需求添加，只保留自己需要的按钮控件和textbox控件即可。

三、代码部分（含解释），采用switch多分支语句编写using System;using System.Drawing;using System.Collections;using SystemponentModel;using System.Windows.Forms;using System.Data;namespace Calc///<summary>/// QQ:479340056 温柔一刀C#简易计算器的实现///</summary>public class CalcForm : System.Windows.Forms.Formprivate System.Windows.Forms.Button btn_0;private System.Windows.Forms.Button btn_1;private System.Windows.Forms.Button btn_2;private System.Windows.Forms.Button btn_3;private System.Windows.Forms.Button btn_4;private System.Windows.Forms.Button btn_5;private System.Windows.Forms.Button btn_6;private System.Windows.Forms.Button btn_7;private System.Windows.Forms.Button btn_8;private System.Windows.Forms.Button btn_9;private System.Windows.Forms.Button btn_add;private System.Windows.Forms.Button btn_sub;private System.Windows.Forms.Button btn_mul;private System.Windows.Forms.Button btn_div;private System.Windows.Forms.Button btn_sqrt;private System.Windows.Forms.Button btn_sign;private System.Windows.Forms.Button btn_equ;private System.Windows.Forms.Button btn_dot;private System.Windows.Forms.Button btn_rev;private System.Windows.Forms.TextBox txtShow;private System.Windows.Forms.Button btn_sqr;private PictureBox pictureBox1;private LinkLabel linkLabel1;///<summary>///必需的设计器变量。

c语言科学计算器程序编写

以下是一个简单的C语言科学计算器程序，可以执行基本的数学运算和科学计算：```c#include <stdio.h>#include <math.h>int main() {char op;double num1, num2, result;printf("请输入一个数学表达式（例如：2 + 3）：\n"); scanf("%lf %c %lf", &num1, &op, &num2);switch(op) {case '+':result = num1 + num2;break;case '-':result = num1 - num2;break;case '*':result = num1 * num2;break;case '/':if(num2 == 0) {printf("错误：除数不能为0！\n");return 0;} else {result = num1 / num2;}break;case '^':result = pow(num1, num2);break;default:printf("错误：不支持的操作符！\n");return 0;}printf("结果为：%lf\n", result);return 0;}```该程序首先要求用户输入一个数学表达式，然后使用scanf函数读取表达式中的操作数和运算符。

接下来，使用switch语句根据运算符执行相应的计算，并将结果存储在result变量中。

最后，程序输出计算结果。

自己写的计算器（加减乘除）代码

科学计算器源代码

科学计算器源代码以下是一个简单的科学计算器的源代码，包含了基本的数学运算、三角函数、指数和对数运算、阶乘和组合运算等功能。

```#include <iostream>#include <cmath>using namespace std;//计算器类class ScientificCalculatorpublic://基本运算double add(double a, double b)return a + b;}double subtract(double a, double b)return a - b;}double multiply(double a, double b)return a * b;}double divide(double a, double b)if (b != 0)return a / b;} elsecout << "Error: Division by zero!" << endl; return 0;}}//三角函数运算double sine(double angle)return sin(angle);}double cosine(double angle)return cos(angle);}double tangent(double angle)return tan(angle);}//指数和对数运算double exponent(double x) return exp(x);}double logarithm(double x) return log10(x);}//阶乘运算double factorial(int n)if (n == 0)return 1;} elseint result = 1;for (int i = 1; i <= n; i++) result *= i;}return result;}}//组合运算if (n >= r)return factorial(n) / (factorial(r) * factorial(n - r));} elsecout << "Error: Invalid input!" << endl;return 0;}}};//主函数int maiScientificCalculator calculator;//进行一些简单的计算cout << "Addition: " << calculator.add(5, 3) << endl;cout << "Subtraction: " << calculator.subtract(5, 3) << endl;cout << "Multiplication: " << calculator.multiply(5, 3) << endl;cout << "Division: " << calculator.divide(5, 3) << endl;//三角函数运算cout << "Sine: " << calculator.sine(0.5) << endl;cout << "Cosine: " << calculator.cosine(0.5) << endl;cout << "Tangent: " << calculator.tangent(0.5) << endl;//指数和对数运算cout << "Exponent: " << calculator.exponent(2) << endl;cout << "Logarithm: " << calculator.logarithm(100) << endl;//阶乘和组合运算cout << "Factorial: " << calculator.factorial(5) << endl;return 0;```这个科学计算器的源代码使用了面向对象的编程思想，将不同的数学运算封装成类的成员函数。

c语言实现虚拟计算器代码

c语言实现虚拟计算器代码以下是一个简单的C语言虚拟计算器代码示例： c.#include <stdio.h>。

int main() {。

char operator;float num1, num2, result;printf("请输入运算符(+, -, , /): ");scanf("%c", &operator);printf("请输入两个数字: ");scanf("%f %f", &num1, &num2);switch(operator) {。

case '+':result = num1 + num2; break;case '-':result = num1 num2; break;case '':result = num1 num2; break;case '/':if(num2 != 0) {。

result = num1 / num2;} else {。

printf("错误，除数不能为0\n"); return 1; // 退出程序。

}。

break;default:printf("错误，无效的运算符\n");return 1; // 退出程序。

}。

printf("结果: %f %c %f = %f\n", num1, operator,num2, result);return 0;}。

这段代码首先要求用户输入运算符和两个数字，然后根据用户输入的运算符进行相应的计算，并输出结果。

在这个示例中，我们使用了switch语句来根据不同的运算符执行不同的计算操作。

另外，我们还对除数为0的情况进行了处理，以避免出现除以0的错误。

当然，这只是一个简单的示例代码，实际的虚拟计算器可能会更复杂，包括更多的功能和更完善的用户界面。

C#编写简易计算器(附源代码)超详细

超详细因为计算器设计的控件太多，不便使用控制台应用程序完成，所以这里使用Windows窗体应用程序，并命名为Calc,如下图所示：向窗体中拖入需要的控件，如下图所示：（完成效果图）结果显示区（作者博客左边的文本框）是TextBox控件，并修改其name为txtShow，按键0~9 为Button 控件，并将其name分别修改为btn_O、btn_1、btn_2、btn_3、btn_4、btn_5、btn_6、btn_7、btn_8、btn_9;按键【负数】的name值修改为btn_sign，按键【.】的name修改为btn_dot，按键【+ - * / 】的name 值分别修改为btn_add、btn_sub、btn_mul、btn_div，按键【=】的name值修改为btn_equ，按键【倒数】的name值修改为btn_rev，按键【平方】的name值修改为btn_sqr,按键【开方】的name值修改为btn_sqrt。

右边的计算器图片空间是PictureBox ，作者博客控件是LinkLabel ，可以不添加，以上所有控件均可按照需求添加，只保留自己需要的按钮控件和textbox控件即可。
