C++实现：判断数字个位是否为3、5或7并统计个数

```cpp #include <iostream> using namespace std; int main() { int a, b, c; cin >> a >> b >> c; int count = 0; // 判断每个数的个位数是否为3、5、7 if (a % 10 == 3 || a % 10 == 5 || a % 10 == 7) { count++; } if (b % 10 == 3 || b % 10 == 5 || b % 10 == 7) { count++; } if (c % 10 == 3 || c % 10 == 5 || c % 10 == 7) { count++; } cout << count << endl; return 0; } ``` ######[AI问答 | 192点数解答 | 2026-05-31 13:05:30]
