C++ 【hello world】 

 1 #include<iostream>  
 2 #include<string>  
 3 #include <limits>  
 4 using namespace std;  
 5   
 6 int main()  
 7 {   
 8     cout << "type: \t\t" << "************size**************"<< endl;  
 9     cout << "bool: \t\t" << "所占字节数：" << sizeof(bool);  
10     cout << "\t最大值：" << (numeric_limits<bool>::max)();  
11     cout << "\t\t最小值：" << (numeric_limits<bool>::min)() << endl;  
12     return 0;  
13 }

C++语言的枚举:

 1 #include<iostream>  
 2 #include<string>  
 3 #include <limits>  
 4 using namespace std;  
 5   
 6 int main()  
 7 {   
 8     enum gg{ apple,blue,green,banana};
 9     for(int i=apple;i<=banana;i++)
10         switch(i){
11         case apple:cout<<"apple"<<endl;break;
12         case banana:cout<<"banana"<<endl;break;
13         default:break;
14         }
15      gg day;
16     enum day = blue;
17     printf("%d",day);
18     return 0;  
19 }
