1、輸出結(jié)果4
#include
void Example(char acHello[])
{
printf("%d",sizeof(acHello));
//printf("%d",strlen(acHello));//自己加的區(qū)別一下
}
void main()
{
char acHello[]="hello";
Example(acHello);
return ;

{
unsigned shortS=0;
S=a+b;
return &S;
}
int main()

unsigned chara=1,b=2;
p=Sum(a,b);
printf("%u+%u",a,b);
printf("=%u\n",*p);
retun 0;
}
3、輸出結(jié)果300 44

ucB=128;
usC=cA+ucB;
printf("0x%x\n",usC);
usC=cA+(short)ucB;
printf("0x%x\n",usC);
usC=(unsigned char)cA+ucB;
printf("0x%x\n",usC);
usC=cA+(char)ucB;
printf("0x%x\n",usC);
}
5、void main()
{論文聯(lián)盟http://wWw.LWlM.cOM
int i;
//characNew[20]={0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0};
//strlen(acNew)輸出結(jié)果10
char acNew[20];
//strlen(acNew)輸出結(jié)果是29
for(i=0;i<10;i++)
{
acNew='0';
}
printf("%d\n",strlen(acNew));
return ;
}
6、void PrintBlue()
{
charpcBlue[]={'b','l','u','e'};
printf("%s",pcBlue);
return 0;
}正確的是
A、pcBlue數(shù)組初始化時(shí)沒(méi)有字符串結(jié)束符
B、數(shù)組pcBlue定義時(shí)必須指定長(zhǎng)度
第二部分簡(jiǎn)答題
1、進(jìn)程與線(xiàn)程的區(qū)別聯(lián)系
2、說(shuō)明時(shí)間片的分配方式有哪些?各有什么優(yōu)缺點(diǎn)?
3、說(shuō)明mutex、semaphore的概念?有何區(qū)別?
4、簡(jiǎn)要描述一下什么是實(shí)時(shí)操作系統(tǒng)和一般操作系統(tǒng),它們有何區(qū)別/
5、有個(gè)例子忘了,主要是要結(jié)合例子說(shuō)明DHCP獲取IP的方式
6、BT與迅雷的工作方式
答案:首先..兩者所采用的協(xié)議完全不同..BT是用的BT專(zhuān)用協(xié)議..像一樓講的一樣..其是一種P2P技術(shù)..即點(diǎn)對(duì)點(diǎn)..在BT網(wǎng)絡(luò)中...很有可能只有一個(gè)種子文件..其它人都是從這個(gè)種子文件進(jìn)行下載的..然后每個(gè)下載者之間再互傳..BT下載從理論上講是下載的同時(shí)必需上傳給其它人分享.
而迅雷所支持的協(xié)議是傳統(tǒng)FTP和HTTP協(xié)議以及迅雷專(zhuān)用協(xié)議...迅雷專(zhuān)用協(xié)議不是典型的P2P協(xié)議..你如果仔細(xì)看迅雷下載過(guò)程的話(huà)就會(huì)發(fā)現(xiàn)...迅雷很大一部份不是P2P.而是搜索資源..比如你用迅雷下載一個(gè)文件..迅
雷是從迅雷服務(wù)器上搜索所有和你下載的文件名稱(chēng)且大小更或者 hash值一樣的資源..然后迅雷可以以多線(xiàn)程從不同的服務(wù)器上面下載...所以迅雷下載快.
BT下載對(duì)應(yīng)的方式是:
┌下載者┐
種子┤ │
└下載者┘
而迅雷的下載方式是:
資源一 ┐
資源二 │--- 下載者
...... │
資源N ┘
7、通常所用的家庭網(wǎng)和校園網(wǎng)有哪些網(wǎng)絡(luò)設(shè)備和服務(wù)器?(結(jié)合TCP/IP協(xié)議棧的知識(shí)說(shuō)明)
8、說(shuō)明TYPE &var表達(dá)式的含義
9、模板與宏的相似之處,有何不同,各有什么優(yōu)缺點(diǎn)?
10、如何申明一個(gè)成員函數(shù),使其可以訪(fǎng)問(wèn)類(lèi)的數(shù)組成員?////好像是這個(gè)意思,具體的問(wèn)法忘了
11、如何申明一個(gè)成員函數(shù),使其不可以修改類(lèi)的數(shù)組成員?//好像是這個(gè)意思,具體的問(wèn)法忘了
12、請(qǐng)說(shuō)明一下IPAD2在上市之前需要做哪些必要地測(cè)試?
13、一個(gè)關(guān)于路由器的地址配置的說(shuō)明表格,就是讓你修改一下表格,使其的默認(rèn)網(wǎng)關(guān)以及分配地址都是按照題目要求中的地址//表格數(shù)據(jù)太多,沒(méi)有記清楚,反正就是熟悉一下路由器、IP地址分配方面的知識(shí)
第三部分編程題
要求寫(xiě)一個(gè)函數(shù),實(shí)現(xiàn)將一個(gè)節(jié)點(diǎn)插入到雙向鏈表中
就這么多了,感覺(jué)自己這趟筆試有打醬油了,最后祝大家好運(yùn)!
1,數(shù)模 模數(shù)轉(zhuǎn)換前的LPF分別是什么作用?
2,兩道放大電路的計(jì)算題啊,應(yīng)該跟簡(jiǎn)單,無(wú)奈不學(xué)基本模電很多年了 木有辦法啊{:74:}
3,若有一家手機(jī)公司給你打電話(huà),提出一些要求,請(qǐng)你寫(xiě)出一套方案來(lái)(研發(fā)的',英文的){:51:}
4,阻抗匹配的理解
5, FIR IIR的區(qū)別,該題目我一看出現(xiàn)在了測(cè)試類(lèi),我就要哭了,為什么為什么,考前20分鐘的時(shí)候,我偏偏對(duì)自己說(shuō),不會(huì)考的,,
