求一个简单的C的语法class A{ public:A(){};A(int i){};}A a(1);//这是什么用法?

public class test(){ public Class a(int i) {} public static #include class A { int a; public:A(int aa=0) { a=aa; } A(){c class A{int i,j;public:static int x;public:A(int a = 0,int b #include class A { public: int n; }; class B:virtual public #include class A { public:A(int i,int j) { a1=i; a2=j; } vir public class a { class A{ int a; public:A(const A& rhs){.} A b=(*this);////// public class A { static int i=0; void method(){ System.out.p yield()的用法class A{public static void main(String[] args){ B c++中,class C:public A,B和class C:public A,public B有什么区别? #include using namespace std;class Box{public:Box(int a,int #includeclass Fuel;class Engine{int a,b;public:Engine(int xa
