[编程入门]二维数组的转置 AC代码

解题思路:

注意事项:

参考代码:

#include

using namespace std;

void Transpose(int arr[3][3])

{

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

{

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

{

if (i < j)

{

arr[i][j] = arr[i][j] ^ arr[j][i];

arr[j][i] = arr[i][j] ^ arr[j][i];

arr[i][j] = arr[i][j] ^ arr[j][i];

}

}

}

}

int main()

{

int arr[3][3];

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

{

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

{

cin >> arr[i][j];

}

}

Transpose(arr);

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

{

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

{

cout << arr[i][j] << " ";

}

cout << endl;

}

return 0;
