简易计算器程序源代码

简易计算器程序源代码下面是一个简易计算器程序的源代码，它可以执行基本的四则运算：```python#定义加法函数def add(x, y):return x + y#定义减法函数def subtract(x, y):return x - y#定义乘法函数def multiply(x, y):return x * y#定义除法函数def divide(x, y):if y == 0:return "除数不能为0"else:return x / y#显示菜单print("选择操作:")print("1. 相加")print("2. 相减")print("3. 相乘")print("4. 相除")#获取用户输入choice = input("输入你的选择(1/2/3/4): ")#获取用户输入的两个数字num1 = float(input("输入第一个数字: "))num2 = float(input("输入第二个数字: "))#根据用户选择执行相应操作if choice == '1':print(num1, "+", num2, "=", add(num1, num2))elif choice == '2':print(num1, "-", num2, "=", subtract(num1, num2)) elif choice == '3':print(num1, "*", num2, "=", multiply(num1, num2)) elif choice == '4':print(num1, "/", num2, "=", divide(num1, num2))else:print("请输入有效的选择")```运行这个程序，你将看到一个简易的计算器菜单。

c语言入门源代码以下是C语言入门的源代码，用于初学者学习和参考： 1. Hello World程序#include <stdio.h>int main() {printf('Hello World!');return 0;}2. 输入输出程序#include <stdio.h>int main() {int num;printf('请输入一个整数：');scanf('%d', &num);printf('您输入的整数是：%d', num);return 0;}3. 判断奇偶数#include <stdio.h>int main() {int num;printf('请输入一个整数：');scanf('%d', &num);if(num % 2 == 0) {printf('%d是偶数', num);} else {printf('%d是奇数', num);}return 0;}4. 计算两个数的和#include <stdio.h>int main() {int num1, num2, sum;printf('请输入两个整数，以空格隔开：');scanf('%d %d', &num1, &num2);sum = num1 + num2;printf('%d和%d的和是：%d', num1, num2, sum); return 0;}5. 计算n的阶乘#include <stdio.h>int main() {int n, i, factorial = 1;printf('请输入一个整数：');scanf('%d', &n);for(i = 1; i <= n; i++) {factorial *= i;}printf('%d的阶乘是：%d', n, factorial);return 0;}以上代码只是C语言入门的一部分，还有很多其他程序可以学习和练习。

编程代码大全

编程代码大全在当今数字化的时代，编程成为了一项至关重要的技能。

无论是开发网站、创建应用程序，还是实现复杂的算法，编程代码都是实现这些目标的基石。

接下来，让我们一同探索各种各样的编程代码。

首先，我们来谈谈 Python 语言。

Python 以其简洁易懂的语法而闻名，对于初学者来说非常友好。

比如下面这段简单的代码，用于计算两个数的和：｀｀｀pythonnum1 ＝ 5num2 ＝ 10result ＝ num1 ＋ num2print(＂两数之和为:＂， result)｀｀｀｀｀｀pythonmy_list ＝ 1, 2, 3, 4, 5my_listappend(6)for num in my_list:print(num)｀｀｀｀｀｀javapublic class Rectangle ｛private int length;private int width;public Rectangle(int length, int width) ｛thislength ＝ length;thiswidth ＝ width;｝public int getArea(）｛return length width;｝public static void main(String args) ｛Rectangle rectangle ＝ new Rectangle(5, 10)；Systemoutprintln(＂矩形面积为: ＂＋ rectanglegetArea(））；｝｝｀｀｀｀｀｀c+＋include ＜iostream>int factorial(int n) ｛if （n ＝＝ 0 ｜｜ n ＝＝ 1) ｛return 1;｝ else ｛return n factorial(n 1)；｝｝int main(）｛int num ＝ 5;std:：cout ＜＜ num ＜＜＂的阶乘为: ＂＜＜ factorial(num) ＜＜std:：endl;return 0;｝｀｀｀JavaScript 常用于网页开发，使网页具有动态交互性。

C语言简单计算器程序源代码

C语言简单计算器程序源代码以下是一个简单的C语言计算器程序的源代码：```c#include <stdio.h>int maichar operator;double num1, num2;printf("请输入运算符：");scanf("%c", &operator);printf("请输入两个数字：");scanf("%lf %lf", &num1, &num2);switch (operator)case '+':printf("%.2lf + %.2lf = %.2lf", num1, num2, num1 + num2); break;case '-':printf("%.2lf - %.2lf = %.2lf", num1, num2, num1 - num2); break;case '*':printf("%.2lf * %.2lf = %.2lf", num1, num2, num1 * num2);break;case '/':if (num2 != 0)printf("%.2lf / %.2lf = %.2lf", num1, num2, num1 / num2);elseprintf("除数不能为0");break;default:printf("无效的运算符");}return 0;```这个程序首先提示用户输入一个运算符，然后再提示输入两个数字。

接下来，程序会根据输入的运算符执行相应的计算，并打印结果。

在计算除法时，程序会检查除数是否为0，如果为0，则打印错误信息。

请注意，这只是一个非常简单的计算器程序，没有考虑很多错误处理情况。
