萌萌哒颜团子: int n, a[10], j = 0, max, min; scanf("%d\n", &n); for (int i = 0; i < n; i++) { scanf("%d", &a[i]); max = a[0]; if (max < a[i]) { max = a[i]; j = i; } } printf("%d %d", max, j); 这种行吗

萌萌哒颜团子: int main() { int i , sign = 1 ; double sum = 0, eps, x = 1; scanf("%lf", &eps); for (int i = 0; 1 / x > eps; i++) { sum +=sign* 1.0 / x; x += 3; sign = -sign; } printf("sum = %f", sum); return 0; } 为什么我的不对呢
