C++中的键值存储

Question

Is there some key value Object in c++ besides STL::map? I want to do something like this

bool addSalary( int salaryBonus , string name, storage &store ){

   if ( store[name] ){
      store[name]+=salaryBonus;
   }else{
      store[name]=saalaryBonus;
   }
return true;

}

But cant use stl::map , i cant find any build in "object" that would behave like key-value storage.

I think you are trying to check if an entry exists. This is possible with std::map . Here is how to do it:

store.find(name) != store.end()
