微软研究院笔试题目
1．#include
#include
class CBuffer
{
char * m_pBuffer;
int m_size;
publc:
CBuffer()
{
m_pBuffer=NULL;
}
~CBuffer()
{
Free();
}
void Allocte(int size)
{
m_size=size;
cBuffer buffer1;
buffer1.SaveString(“Microsoft”);
printf(buffer1.GetBuffer());
}
}
找出Allocate, SaveString, main的错误。
2．打印“Welcome MSR Asia”
#include
#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;i<=32;i++)
{
name[1]=‘{post.content}‘;
}
//copy “Welcome” to name
name=“Welcome”;
//Append a blank char
name[8]=”;
//Append string to name
strcat(name,GetName());
//print out
printf(name);
}
找出程序中的错误。
3．#include
class A
{
public:
void FuncA()
{
printf(“FuncA called\n”);
}
virtual void FuncB()
{
printf(“FuncB called\n”);
}
};
class B: public A
{
public:
void FuncA()
{
A::FuncA();
printf(“FuncAB called\n”);
}
virtual void FuncB()
{
printf(“FuncBB called\n”);
}
};
void main(void)
{
B b;
A *pa;
pa=&b;
A *pa2=new A;
b.FuncA();
b.FuncB();
pa->FuncA();
pa->FuncB();
pa2->FuncA();
pa2->FuncB();
delete pa2;
}
What is the output of the above program?
4．#include
#include
int FindSubString(char* pch)
{
int count=0;
char* p1=pch;
while(*p1!=‘{post.content}’)
{
if(*p1==p1[1]-1)
{
p1++;
count++;
}
else
{
break;
}
}
int count2=count;
while(*p1!=‘{post.content}’)
{
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!=‘{post.content}’)
{
int count=FindSubString(p1);
if(count>0)
{
*p2++=*p1;
sprintf(p2, “%I”, count);
while(*p2!= ‘{post.content}’)
{
p2++;
}
p1+=count+count+1;
}
else
{
*p2++=*p1++;
}
}
}
void main(void)
{
char text[32]=“XYBCDCBABABA”;
ModifyString(text);
printf(text);
}
In the main() function, after ModifyString(text) is called, what’s the
value of ‘text’?
