Question

如题所述

Answer 1

#include "stdafx.h"

#include <stdio.h>

#include <iostream>

using namespace std;

int _tmain(int argc, _TCHAR* argv[])

{

    int arr[4][4],i,j;

    int temp[4][4];

    for (i=0;i<=3;i++)

    {

        printf("请输入第%d行数据：",(i+1));

        for (j=0;j<=3;j++)

            scanf_s("%d",&arr[i][j]);

    }

    for (i=0;i<=3;i++)

        for(j=0;j<=3;j++)

        {

            temp[i][j]=arr[j][i];

        }

    printf("转换后的矩阵为：\n");

    for (i=0;i<=3;i++)

        for(j=0;j<=3;j++)

            {

                printf("%d ",temp[i][j]);

                if(j==3)

                    printf("\n");

            }

    system("pause");

    return 0;
