C语言程序设计教程（第三版）课后习题8.4 （Java代码）

解题思路:

注意事项:





参考代码:

import java.util.*;

public class Main1030 {

public static void main(String[] args) {

Scanner sc = new Scanner(System.in);

int[][] a = new int[3][3];

for (int i = 0; i < 3; i++) {

for (int j = 0; j < 3; j++) {

a[i][j] = sc.nextInt();

}

}

int n = 0;

for (int i = 0; i < 3; i++) {

for (int j = 0; j < 3; j++) {

if (n == 1 || n == 2 || n == 5) {

int x = a[i][j];

a[i][j] = a[j][i];

a[j][i] = x;

}

System.out.print(a[i][j] + " ");

n++;

if (n % 3 == 0)

System.out.println();

}

}

}

}
