inputName(numbers);
inputScore(numbers);
rank(inputName(numbers), inputScore(numbers), numbers);
这里有问题，他会重复调用两次。
for (i = 0; i < numbers; i++) {
if (score[i] < score[i + 1]) {
change = score[i + 1];
score[i + 1] = score[i];
score[i] = change;
middle = name[i + 1];
name[i + 1] = name[i];
name[i] = middle;
}
}
这个循环也有问题，会越界的。
改成：
rank(inputName(numbers), inputScore(numbers), numbers);

for (i = 0; i < numbers-1; i++) {
if (score[i] < score[i + 1]) {
change = score[i + 1];
score[i + 1] = score[i];
score[i] = change;
middle = name[i + 1];
name[i + 1] = name[i];
name[i] = middle;
}
}

Java code

        for (i = 0; i < numbers-1; i++) {            if (score[i] < score[i + 1]) {                change = score[i + 1];                score[i + 1] = score[i];                score[i] = change;                middle = name[i + 1];                name[i + 1] = name[i];                name[i] = middle;            }        }
