      軟件工程師筆試題

        軟件工程師是從事軟件開發(fā)相關(guān)工作的人員的統(tǒng)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(nèi)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(gòu)函數(shù)

        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(gòu)函數(shù)是非virtual的,故析構(gòu)的時候按照指針的類型進行析構(gòu)

        }

        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(gòu)造函數(shù)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(diào)用拷貝構(gòu)造函數(shù)

        A c(a); //調(diào)用拷貝構(gòu)造

        A d;

        d=a; //賦值

        }

        輸出:

        Construct A by default //構(gòu)造對象a

        consttuct A by copy //拷貝構(gòu)造b

        consttuct A by copy //拷貝構(gòu)造c

        Construct A by default //構(gòu)造a

        cosnt A by operator = //賦值d=a

        Destruct A

        Destruct A

        Destruct A

        Destruct A

        2、 考察函數(shù)指針

        void func(char* a)

        {

        cout<

        }

        int main()

        {

        void (*fp)(char*); //填空處

        fp = func; //函數(shù)名func相當于函數(shù)的地址,將其賦給函數(shù)指針fp

        char* s="helloc";

        fp(s);

        }
