unsigned char a[][5]={
{1,2,3,4,5},
{6,7,8,9,10},
{1,5,6,5,5},
{6,6,6,4,6}
};
unsigned char * b[][4]={
{a[1],a[2],a[3],a[0]},
{a[0],a[2],a[2],a[2]},
{a[1],a[0],a[0],a[3]}
};
while (1) {
printf ("%d",*(*b[1]));
}
}
这个函数能输出需要的12345156551565515655 吗？
该函数是简化版
只在了解能否通过*（*b[1]）通过 数组b访问到a 中的数组 从而得到数组的任意组合 麻烦大家了
在线等待
