小北的身高是 1.65 米。班上有 n 个小朋友，小北想和身高最接近自己的人交朋友。如果有多个小朋友与小北的身高差相同，小北想和其中身高较矮的第一个小朋友做朋友。横线处应该填入的是（ ）。
int n, i;
float target, h, best_height, min_diff, diff;
cout << "请输入小朋友的人数: ";
cin >> n;
target = 1.65;
best_height = 0.0;
min_diff = 100.0;
for (i = 0; i < n; i++) {
cout << "请输入第 " << i << " 个小朋友的身高: ";
cin >> h;
diff = abs(h - target);
if (____________________) { // L1
min_diff = diff;
best_height = h;
}
}
cout << "小北的朋友身高为: " << best_height;
- A. diff < min_diff || (diff == min_diff && h < best_height)
- B. diff <= min_diff && h < best_height
- C. diff < min_diff && h < best_height
- D. diff < min_diff || h < best_height
正确答案：A
