We iterate over enum members in a for loop. for season in Season: print(season.name, season.value) Here we print their names and values. $ python main.py Season.SPRING Season.SUMMER Season.AUTUMN Season.WINTER SPRING 5 SUMMER 6 AUTUMN 7 WINTER 8 Automatic values Python enum values can be...
int i,j,k,counter=0,loop; for(i=red;i<=black;i++) for(j=red;j<=black;j++) if(i!=j){ //前两个球颜色不同 for(k=red;k<=black;k++) if(k!=i&&k!=j){ //第三个球不同于前两个,满足要求 counter++; if((counter)%22==0){ //每屏显示22行 cout<<"请按回车键继续"; ci...
In this example, you use a for loop to iterate over the members of Flavor. Note that members are produced in the same order as they were defined in the class definition.When you’re iterating over an enumeration, you can access the .name and .value attributes as you go:...

for(int i=0;i<A.length;i++) { for(int j=0;j<B.length;j++) { if(A[i].id==B[j].id) { resultSet.add(A[i]); break; } } } return resultSet; 1. 可以看出,当B表数据较大时不适合使用in(),因为它会B表数据全部遍历一次. 如:A表有10000条记录,B表有1000000条记录,那么最多有...
When you define an enum type, the blueprint for the variable is created. Here's how you can create variables of enum types. enum boolean {false, true}; enum boolean check; // declaring an enum variable Here, a variablecheckof the typeenum booleanis created. ...
In C++11,everythingcan be used at compile time. You can convert your enums, loop over them,find their max,statically enforce conventions, and pass along the results as template arguments or toconstexprfunctions. All the reflection is available for your metaprogramming needs. ...
