C++实现：输入两位正整数计算其十位与个位数字之和

```cpp #include <iostream> using namespace std; int main() { int num; cout << "请输入一个两位正整数: "; cin >> num; int tens = num / 10; int units = num % 10; int sum = tens + units; cout << "十位数字: " << tens << endl; cout << "个位数字: " << units << endl; cout << "数字之和: " << sum << endl; return 0; } ``` ######[AI问答 | 111点数解答 | 2025-11-23 17:09:48]
