2、ublic: c() coutconstuct c c() coutdestruct c ; class d:public b, public c public: d() coutconstsruct d d() coutdestruct 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)

3、函數(shù) 1、class parent public: parent()coutparent construct parent() coutparent destruct ; class child : public parent public: child() coutchild construct child() coutchild destruct ; int main() parent *p; child *c = new child(); p = c; delete p; 由于析構(gòu)函數(shù)是非virtual的，故析構(gòu)的時(shí)候根據(jù)指針的類型進(jìn)行析構(gòu) 輸出： parent construct ch

4、ild construct parent destruct 2、 考察初始化列表的寫(xiě)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)分。 class a public: a() coutconstruct a by default a(const a a) coutconsttuct a

5、 by copy a operator =(const a a) coutcosnt a by operator = a() coutdestruct 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(duì)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)(cha
