1、

  #include
  
class CBuffer
  {
  
char * m_pBuffer;
  
int m_size;
  publc:
   CBuffer()
   {
   m_pBuffer
=NULL;
   }
  
~CBuffer()
   {
   Free();
   }
  
void Allocte(int size)
   {
   m_size
=size;
   m_pBuffer
= new char[size];
   }
  
private:
  
void Free()
   {
  
if(m_pBuffer!=NULL)
   {
   delete m_pBuffer;
   m_pBuffer
=NULL;
   }
   }
  
public:
  
void SaveString(const char* pText) const
   {
   strcpy(m_pBuffer, pText);
  
char* GetBuffer() const
   {
  
return m_pBuffer;
   }
   };
  
void main (int argc, char* argv[])
   {
   cBuffer buffer1;
   buffer1.SaveString(“Microsoft”);
   printf(buffer1.GetBuffer());
   }
  }

找出Allocate, SaveString, main的错误。

 

2、打印“Welcome MSR Asia”

  #include
  
char * GetName (void)
  {
  
//To return “MSR Asia” String
   char name[]=“MSR Asia”;
  
return name;
  }
  
void main(int argc, char* argv[])
  {
  
char name[32];
  
//Fill in zeros into name
   for(int i=0;iFuncA();
   pa
->FuncB();
   pa2
->FuncA();
   pa2
->FuncB();
   delete pa2;
  }

What is the output of the above program?

3、

#include
  
int FindSubString(char* pch)
  {
  
int count=0;
  
char* p1=pch;
  
while(*p1!=‘’)
   {
  
if(*p1==p1[1]-1)
   {
   p1
++;
   count
++;
   }
  
else
   {
  
break;
   }
   }
  
int count2=count;
  
while(*p1!=‘’)
   {
  
if(*p1!==p1[1]+1)
   {
   p1
++;
   count2
--;
   }
  
else
   {
  
break;
   }
  
if(count2==0)
  
return count;
  
return 0;
  }
  
void ModifyString(char* pText)
  {
  
char* p1=pText;
  
char* p2=p1;
  
while(*p1!=‘’)
   {
  
int count=FindSubString(p1);
  
if(count>0)
   {
  
*p2++=*p1;
   sprintf(p2, “
%I”, count);
  
while(*p2!= ‘’)
   {
   p2
++;
   }
   p1
+=count+count+1;
   }
  
else
   {
  
*p2++=*p1++;
   }
   }
  }
  
void main(void)
  {
  
char text[32]=“XYBCDCBABABA”;
   ModifyString(text);
   printf(text);
  }

In the main() function, afterModifyString(text) is called, what’s the value of ‘text’?
