二维数组交换行和列

#include<stdio.h>
int main()
{
    int a[2][3] = { 1, 2, 3, 4, 5, 6 };            //定义数组
    int b[3][2],j,k;
    for (j = 0; j <= 1;j++)                        //循环交换
    {
        for (k = 0; k <= 2;k++)
        {
            b[k][j] = a[j][k];                    //把行和列交换
        }
    }
    for (j = 0; j <= 2; j++)                    //输出
    {
        for (k = 0; k <= 1;k++)
        {
            printf("%d", b[j][k]);
        }
        printf("\n");
    }

    return 0;
