题目描述 雪花 一片两片三四片， 五片六片七八片， 九片十片无数片， 飞入梅花看不见。 试编一程序，算算《雪花》第一句中数字1、2、3、4的和是多少？ 输出 先输出提示语句“1+2+3+4=”，然后输出它们的和。

```cpp #include <iostream> using namespace std; int main() { cout << " " << endl; cout << " " << endl; cout << " ....#." << endl; cout << " #.......##...." << endl; cout << " .......## " << endl; cout << " ........... #...# #...#" << endl; cout << " ##* #.#.# #.#.#" << endl; cout << " *## #.#.# #.#.#" << endl; cout << " ...#*..*.... #...# #...#" << endl; cout << " ...." << endl; return 0; } ``` ```cpp #include <iostream> using namespace std; int main() { int length = 880; int width = 500; int area = length * width; cout << area << endl; return 0; } ``` ```cpp #include <iostream> using namespace std; int main() { int sum = 1 + 2 + 3 + 4; cout << "1+2+3+4=" << sum << endl; return 0; } ``` [2025-12-15 17:50:18 | AI问答 | 286点数解答]
