我不明白为什么这个for循环工作

void managingTable(unsigned char table[256][256][1])
{
    for (unsigned int x = 0; x <= 255; x++)
    {
        for (unsigned int y = 0; y <= 255; y++)
        {
            doSomethingWithTable();
        }
    }
}

当y达到255但在x上没有迭代时,这不起作用

void managingTable(unsigned char table[256][256][1])
{
    unsigned int x = 0;
    unsigned int y = 0;

    for (x; x <= 255; x++)
    {
        for (y; y <= 255; y++)
        {
            doSomethingWithTable();
        }
    }
}

这也行不通:

void managingTable(unsigned char table[256][256][1])
{
    unsigned int x = 0;
    unsigned int y …
