C++ - How do I insert multiple values into a vector, each with a different index? -

currently have vector holding references rooms connected specific room:

rooms.at(1).connectedrooms = { &rooms.at(2), &rooms.at(3), &rooms.at(4), &rooms.at(5)}; 

however use enum index, rather integer, instead of rooms.at(1).connectedrooms.at(0) use rooms.at(1).connectedrooms.at(north) makes more sense , allows used more , legibly in switch statements.

the enum looks like

enum directions { north, east, south, west}; 

is there way on 1 line, example (this code doesn't work, it's do):

rooms.at(1).connectedrooms[north, east, south, west] = {&rooms.at(2), &rooms.at(3), &rooms.at(4), &rooms.at(5)}; 

rather longer

rooms.at(1).connectedrooms[north] = &rooms.at(2); rooms.at(1).connectedrooms[east] = &rooms.at(3); rooms.at(1).connectedrooms[south] = &rooms.at(4); rooms.at(1).connectedrooms[west] = &rooms.at(5); 

thanks

you can assign integer values enum constants:

enum directions { north = 0, east = 1, south = 2, west = 3 }; 

and keep assignment is:

rooms.at(1).connectedrooms = { &rooms.at(2), &rooms.at(3), &rooms.at(4), &rooms.at(5)}; 

edit: per comment below, please aware way holding pointers vector members dangerous , not considered practice. remember std::vector dynamic, may decide change location of memory area anytime needs to, such when grows...
