为啥子程序s值穿不到主程序k呢
int shuzu(int two[5][5],int s)
{   int m,n;
    s=two[0][0];
    for(m=0;m<5;m++)
        for(n=0;n<5;n++)
        {   if(n==m)
            {   if(two[m][n]<s)
                  s=two[m][n];
            }
            if((m+n)==4)
            {   if(two[m][n]<s)
                    s=two[m][n];
            }
         }

}
main()
{   int i,j,k;
    int one[5][5];
    for(i=0;i<5;i++)
        for(j=0;j<5;j++)
            scanf("%d",&one[i][j]);
    for(i=0;i<5;i++)
    {    for(j=0;j<5;j++)
            printf("%d    ",one[i][j]);
         printf("\n");
    }

    shuzu(one,k);
    printf("The small one is:%d",k);

}
