二维数组进行行的排序

#include "stdio.h"
main()
{
unsigned int m[2][4],z,t;
unsigned int j,k;
printf("input 8 numbers:\n");
for (j=0;j<2;j++)
for (k=0;k<4;k++)
scanf ("%d",&m[j][k]);
for (j=0;j<2;j++)
{
for (k=0;k<4;k++)
printf("%5d",m[j][k]);
printf("\n");
}
for (int z=0;z<2;z++)
{
for (int j=0;j<2;j++)
{
for(k=0;k<4-1-j;k++)
{
if (m[z][k]>m[z][k+1])
{
int t=m[z][k];
m[z][k]=m[z][k+1];
m[z][k+1]=t;
}
}
}
}

printf("Sort results:\n");
for (k=0;k<4;k++)
printf("%d",m[z][k]);

}

可以问一下，这个二维数组排序是哪里不对吗？每次输值进去都不能进行排序。

#include "stdio.h"
int main()
{
    unsigned int m[2][4],z,t;
    unsigned int j,k;
    printf("input 8 numbers:\n");
    for (j=0; j<2; j++)
        for (k=0; k<4; k++)
            scanf ("%d",&m[j][k]);
    for (j=0; j<2; j++)
    {
        for (k=0; k<4; k++)
            printf("%5d",m[j][k]);
        printf("\n");
    }
    for (int z=0; z<2; z++)
    {
        for (int j=0; j<4-1; j++)
        {
            for(k=0; k<4-1-j; k++)
            {
                if (m[j][k]>m[z][k+1])
                {
                    int t=m[z][k];
                    m[z][k]=m[z][k+1];
                    m[z][k+1]=t;
                }
            }
        }
    }
    for (int z=0; z<4; z++)
    {
        for (int j=0; j<2-1; j++)
        {
            for(k=0; k<2-1-j; k++)
            {
                if (m[k][z]>m[k+1][z])
                {
                    int t=m[k][z];
                    m[k][z]=m[k+1][z];
                    m[k+1][z]=t;
                }
            }
        }
    }
    printf("Sort results:\n");
    for (k=0; k<2; k++) {
        for (z=0; z<4; z++)
            printf("%5d",m[k][z]);
        printf("\n");
    }

    return 0;
}
