虽然是Java语言，看懂了可以适用任何语言
public class XiTi466 {
public static void main(String[] args) {
int score[] = new int[10];
for (int i = 0; i < score.length; i++) {
score[i] = i;
}
System.out.print("赋值后的数组：");
for (int i = 0; i < score.length; i++) {
System.out.print(score[i] + " ");
}
System.out.println();
// 这是首尾互换的过程
for (int i = 0; i < score.length / 2; i++) { //score.length是求数组score的长度
int temp = 0;
temp = score[i];
score[i] = score[score.length - (i + 1)];
score[score.length - (i + 1)] = temp;
}
System.out.print("交换后的数组：");
for (int i = 0; i < score.length; i++) {
System.out.print(score[i] + " ");
}
}
}
