计算器源码（计算器编程代码）

#include<stdio.h>int main() { double num1 = 0; //输入1 double num2 = 0; //输入2 char ch; //操作 double ret = 0; //结果 printf( "输入第一个数:" ); scanf( "%lf", &num1 ); printf( "输入第二个数:" ); scanf( "%lf", &num2 ); printf( "操作[+ - * /]:" ); getchar(); scanf( "%c", &ch ); switch( ch ) { case '+': ret = num1 + num2; break; case '-': ret = num1 - num2; break; case '*': ret = num1 * num2; break; case '/': ret = num1 / num2; break; default: break; } printf( "结果:%.2lf\n", ret ); return 0;} 写个简单易懂的，你操作计算器的步骤就是编写程序的思路呀
