C++实现简单整数计算器：支持四则运算，处理除零与无效操作符问题

```cpp #include <iostream> using namespace std; int main() { int num1, num2; char op; cin >> num1 >> num2 >> op; if (op == '+') { cout << num1 + num2 << endl; } else if (op == '-') { cout << num1 - num2 << endl; } else if (op == '*') { cout << num1 * num2 << endl; } else if (op == '/') { if (num2 == 0) { cout << "Divided by zero!" << endl; } else { cout << num1 / num2 << endl; } } else { cout << "Invalid operator!" << endl; } return 0; } ``` ######[AI问答 | 194点数解答 | 2025-12-12 19:35:47]
