public interface IFly{
void Fly()
}
public class Plane : IFly
{
public void Fly()
{
//code hear
}
}
public class Bird : IFly
{
public void Fly()
{
//code hear
}
}
这称为列表初始化，即以N的值来初始化fly。
fly可以是原始类型的变量，如：
#define N 99
int fly{N}
也可以是复合类型的变量，如:
#define N 99
struct bird
{
int high
}fly{N}
不过，这应该是c++的新语法特性，c语言好像没有这种特性。
下面是一个使用列表初始化的综合的例子：
#include<iostream>
#include<cstdio>
using namespace std
enum color
{
red,
green,
blue
}
struct stu
{
int id
char sex
}
class cls
{
public:
cls(string s,int i):s(s),i(i)
{}
string s
int i
}
void f1()
{
char c{'G'}
int i{100}
float f{1.11}
double d{2.222222}
char* str{(char*)"ok"}
enum color cl{green}
struct stu stu1{1234,'m'}
cls o1{"aaa",1}
printf("%c %d %f %lf %s\n",
c,i,f,d,str)
printf("%d {%d,%c}\n",
cl,stu1.id,stu1.sex)
cout<<o1.s<<" "<<o1.i
cout<<endl
}
void f2()
{
char c={'G'}
int i={100}
float f={1.11}
double d={2.222222}
char* str={(char*)"ok"}
enum color cl={green}
struct stu stu1={1234,'m'}
cls o1={"aaa",1}
printf("%c %d %f %lf %s\n",
c,i,f,d,str)
printf("%d {%d,%c}\n",
cl,stu1.id,stu1.sex)
cout<<o1.s<<" "<<o1.i
cout<<endl
}
int main()
{
f1()
cout<<endl
f2()
return 0
}
输出结果
