M型结构(名词解释)

函数readDat()的功能是从文件IN22.DAT中读取20行数据存放到字符串数组xx中(每行字符串长度均小于80)。请编制函数jsSort()，该函数的功能是：以行为单位对字符串按下面给定的条件进行排序，排序后的结果仍按行重新存入字符串数组xx中，最后调用函数writeDat()把结果xx输出到文件OUT22.DAT中。
条件：从字符串中间一分为二，左边部分按字符的ASCII值降序排序，排序后，左边部分与右边部分按例子所示进行交换。如果原字符串长度为奇数，则最中间的字符不参加处理，字符仍放在原位置上。
例如，位置 0 1 2 3 4 5 6 7 8
源字符串 a b c d h g f e
2 3 4 9 8 7 6 5
则处理后字符串 h g f e d c b a
8 7 6 5 9 4 3 2
注意：部分程序已给出。
请勿改动主函数main()、读函数readDat()和写函数writeDat()的内容。
inc lude〈 st dio. h＞
inc lude〈 s t ring. h＞
inc lude〈 conio, h＞
char xx[20] [80];
void jsSort()
{
}
main ()
{
readDat ();
jsSort ();
writeDat ();
}
readDat ()
{
FILE in;
int i=0;
char p;
in= fopen("IN22.DAT", "r");
while(i〈 20 && fgets(xx[i], 80, in) != NULL)
{
p = strchr(xx[i], '\n');
if(p) p = 0;
i++;
}
fclose(in);
}
writeDat ()
{
FILE out;
int i;
clrscr ();
ut = fopen("OUT22.DAT", "w");
for(i = 0; i〈 20; i++)
{
printf("%skn", xx[i]);
fprintf(out, "%sin", xx[i]);
}
fclose(out);
}

根据施工总平面图没计编制施工方案和施工进度计划是否正确？如不正确，应该怎样改正？

One day I can hear the faint rustle of autumn coming. The next day I can’t. One evening summer leaks away into the cool night sky, but the next morning it’s back again. But there is headway. Birdsong has gone, and is【46】__ (replace) by a whining bag-piping of insect creation. I look out across the pasture as dusk【47】(begin) and see a shining galaxy of airborne bugs. What would it be like, I wonder, to have an【48】awareof the actual number of insects on this farm？
I ask myself a version of this question every day: "Have you ever really looked at…？”You can【49】in the blank yourself.
Every day I am blinded by【50】familiar. I open our beehive, which is filled with honey, and the particularity of the honeybees, and even of their community, somehow escapes me, if only because I’ve been living with honeybees a good part of my life. I remember the phrase, "keep your eyes【51】 (peel) , ”and maybe that’s what I need, a good peeling.
Again and【52】, I find myself trying to really look at what I' m seeing. It happened the other afternoon, high on a nearby mountain. A dragonfly had settled on the denuded tip of a pine bough. It clung, still as only a dragonfly can be. Then it flicked upward and caught a midge and settled on the bough again, adjusting【53】(precise) to the wind. I see dragonflies【54】 (quiver) in the insect clouds above my pasture, too. I am always aware, however , that there’s no such thing as really looking.
What I want to see is invisible anyway: the prehistoric depth of time embodied in the form. of those dragonflies, the pressure of life itself, the web of【55】(relate) that bind us all together. I find myself trying to【56】witthe moment when the accident of life becomes a continued purpose. But this is a small farm, and, being human, 1 keep【57】(come) up against the limits of what a human can see.
This morning I found a spider resting—or perhaps hunting—on the leaf of a hydrangea, the axis of the spider’s abdomen perfectly aligned with the axis of the leaf. What I noticed was the symmetry of their placement, the way spider, and leaf resembled【58】_other. What I wanted to determine was the spider’s intent. If I【59】c, I would have asked it, "What are you doing？” Or, better yet, "Who are you？” But all I could do was look—and realizing that I was looking—make the【60】b__of what I’d seen.
