仔细阅读 说明以下代码的实现功能

代码段A：
/* */

unsined short function(unsigned char *gpszCrr)
{
unsied char *ipCh;
unsined short iusMaxLen;
for(ipCh=(byte *)gpszCrr, iusMaxlen=65535;) ((*ipCh !='\n') && (iusMaxlen>0)); ipCh++, iusMaxlen--);

return (ipCh - gpszCrr);

}

代码段B：

void CExample::Process(unsigned int nLength, char *pszSource, char *pszDset)
{
short nTemp;
int i,j;
char szBuff[30];
for(i=0; i<nLength; i++)
{
nTemp=pszSource[i];
nTemp= (nTemp>>4)& 0x000f;
if(nTemp<10)
pszDset[2*i] = nTemp + '0';
else pszDset[2*i] ='';
nTemp = pszSource[i] & 0x000f;
}
pszDset[2*i] = '\0';
strcpy(szBuff, pszDset);
nLength = nLength*2;
i=j=0;
for(i=0; i<nLength; i++)
if(szBuff[i] != '')
pszDset[j++] = szBuff[i];
pszDset[j]='\0';
}
代码段C:
void process (char* elem, int l, int r)
{
int i=l, j=r;
char* a=&elem[l];

while(i<j)
{
while(i<j && *a<elem[j])
j--;
if(i<j)
{
elem[i] = elem[j];
i++;
}
while(i<j && elem[i]<*a)
i++;
if(i<j)
{
elem[j] = elem[i];
j--;
}

}
elem[i]=*a;
if(l<i)
process(elem, l, i-l);
if(i<r)
process(elem, j+1, r);
}
代码段D：
#include<iostream>
#include<deque>
#include<algorithm>

using namespace std;

void print(int elem)
{
cout<<elem<<'';
}
int main()
{
deque<int>coll;

for(int i=l; i<=9; ++i)
coll.push_back(i);
deque<int>::iterator pos2;
pos2 = find(coll.begin(),coll.end(),7);
for_each(posl, pos2,print);
cout<<endl;
deque<int>::reverse_iterator rpos1(pos1);
deque<int>::reverse_iterator rpos2(pos2);

for_each(rpos2, rpos1, print);
cout<<endl;
}

最后一个题的
for_each(posl, pos2,print); //pos1是什么呀?

找出以下各代码段的错误
代码段A
/* */
int main(int argc, char* argv[])
{
FILE *f;

char s[] = "this is a string";
char c = '\n';
f=fopen("output.txt","r");
fprintf(f, "%s%c", s, c);
return 0;

}

代码段B：

class CBaseThread : public CWinThread
{
public:
CBaseThread(CWnd* pWnd, HDC hDC);
virtual ~CBaseThread();
virtual void BeginProcess()=0;
};

class CHastThread : public CBaseThread
{
CHastTread();
CHastThread(CWnd* pWnd, HDC hDC, CPoint ptPos, UINT ThreadId);
Virtual void BeginProcess();
protected:
virtual ~CHastThread();

};

class CInqThread : public CBaseThread
{
public:
CInqThread();
CInqThread(CWnd* pWnd, HDC hDC, CPoint ptPos, UINT ThreadId);
virtual void BeginProcess();
Protected:
virtual ~CInqThread();

};
void CMainFrame::startThreads()
{
CBaseThread pThread[3];
CPoint Pos(48,78);
UINT nThreadId = 0;
pThread[0] = new CBaseThread(this, m_pDC->GetSafeHdc());
pThread[1] = new CHaseThread(this, m_pDC->GetSafeHdc(), Pos, ++nThreadId);
pThread[2] = new CInqThread(this, m_pDC->GetSafeHdc(),Pos, ++nThreadId);
}

楼上的 打错了 是 for_each(rposl, rpos2,print); //pos1是什么呀?

[CloudOfFly]

那里少了一句
deque<int>::iterator pos1;
pos1 = find(coll.begin(), coll.end(), 2);

[cunsh]

那最后一个是2 3 4 5 6
区间是[first, last)

找错的第一题的fopen "r" 是读文件的要改成写的.

[CloudOfFly]

郁闷了 都一天了还没人来帮忙啊

[guyanhun]

int main(int argc, char* argv[])
{
FILE *f;

char s[] = "this is a string";
char c = '\n';
f=fopen("output.txt","r");
fprintf(f, "%s%c", s, c);
return 0;

}

1。加上文件是否成功打开的判断，失败直接exit。
2。打开方式要改，
3。最后要 fclose 文件。
