编写科学计算器的程序可以通过多种编程语言实现,包括C语言、C++、Java和C等。下面我将分别提供C语言和Java的示例代码,以帮助你理解如何编写科学计算器程序。
C语言示例
```c
include include int main() { double a, b, result; char operation; printf("请输入表达式(例如:3*(4+6)-(5-2)^3):"); scanf("%lf%c%lf", &a, &operation, &b); switch (operation) { case '+': result = a + b; break; case '-': result = a - b; break; case '*': result = a * b; break; case '/': if (b != 0) { result = a / b; } else { printf("错误:除数不能为零。\n"); return 1; } break; case '^': result = pow(a, b); break; case 's': result = sin(a); break; case 'c': result = cos(a); break; case 't': result = tan(a); break; case 'e': result = exp(a); break; case 'l': result = log(a); break; case 'f': result = factorial(a); break; case 'r': result = 1 / a; break; case 'x^2': result = a * a; break; case '1/x': if (a != 0) { result = 1 / a; } else { printf("错误:除数不能为零。\n"); return 1; } break; default: printf("错误:无效的操作符。\n"); return 1; } printf("结果:%.2lf\n", result); return 0; } double factorial(double n) { if (n == 0) { return 1; } return n * factorial(n - 1); } ``` Java示例
