軟件工程師筆試題

  軟件工程師是從事軟件開發(fā)相關工作的人員的統稱。下面就由學習啦小編為大家介紹一下軟件工程師筆試題的文章,歡迎閱讀。

  軟件工程師筆試題篇1

  考察虛繼承內存體系

  class A

  {

  public:

  A() { cout<<"Construct A"<

  ~A() { cout<<"Destruct A"<

  void speak() { cout<<"A is speaking!"<

  };

  class B:public virtual A

  {

  public:

  B() { cout<<"Construct B"<

  ~B() { cout<<"Destruct B"<

  };

  class C:public virtual A

  {

  public:

  C() { cout<<"Constuct C"<

  ~C() { cout<<"Destruct C"<

  };

  class D:public B, public C

  {

  public:

  D(){ cout<<"Constsruct D"<

  ~D(){ cout<<"Destruct D"<

  };

  int main()

  {

  D *p = new D();

  p->speak();

  delete p;

  }

  輸出:

  Construct A

  Construct B

  Constuct C

  Constsruct D

  A is speaking!

  Destruct D

  Destruct C

  Destruct B

  Destruct A

  軟件工程師筆試題篇2

  考察非虛析構函數

  1、class Parent

  {

  public:

  Parent(){cout<<"Parent construct"<

  ~Parent(){ cout<<"Parent destruct "<

  };

  class Child : public Parent

  {

  public:

  Child() { cout<<"Child construct "<

  ~Child() {cout<<"child destruct"<

  };

  int main()

  {

  Parent *p;

  Child *c = new Child();

  p = c;

  delete p; 因為析構函數是非virtual的,故析構的時候按照指針的類型進行析構

  }

  輸出:

  Parent construct

  Child Construct

  Parent destruct

  2、 考察初始化列表的寫法

  class A

  {

  public:

  A(int x, int y, int z):a=x,b=y,c=z {} (1)

  A(int x, int y, int z):a(x),b(y),c(z){} (2)

  private:

  int a;

  int b;

  int c;

  };

  int main()

  {

  A a(1,2,3);

  }

  軟件工程師筆試題篇3

  1、考察拷貝構造函數和賦值的區(qū)別。

  class A

  {

  public:

  A() { cout<<"Construct A by default"<

  A(const A& a) { cout<<"consttuct A by copy"<

  A& operator =(const A& a) { cout<<"cosnt A by operator ="<

  ~A() { cout<<"Destruct A"<

  };

  int main()

  {

  A a;

  A b=a; //調用拷貝構造函數

  A c(a); //調用拷貝構造

  A d;

  d=a; //賦值

  }

  輸出:

  Construct A by default //構造對象a

  consttuct A by copy //拷貝構造b

  consttuct A by copy //拷貝構造c

  Construct A by default //構造a

  cosnt A by operator = //賦值d=a

  Destruct A

  Destruct A

  Destruct A

  Destruct A

  2、 考察函數指針

  void func(char* a)

  {

  cout<

  }

  int main()

  {

  void (*fp)(char*); //填空處

  fp = func; //函數名func相當于函數的地址,將其賦給函數指針fp

  char* s="helloc";

  fp(s);

  }
