用C语言判断：输入整数是否为与7相关的数

```c #include <stdio.h> int hasSeven(int num) { if (num % 7 == 0) { return 1; } int temp = num; while (temp > 0) { if (temp % 10 == 7) { return 1; } temp /= 10; } return 0; } int main() { int num; scanf("%d", &num); if (hasSeven(num)) { printf("%d\n", num); } else { printf("no!\n"); } return 0; } ``` ######[AI写代码神器 | 160点数解答 | 2024-10-08 22:03:48]
