Question

My application can only process up to a certain number of entry in the map structure, how do I specify that limit in my code so that my code does not get overwhelmed (for lack of better term). Is there a way to specify the max limit when defining the variable of type map?

Thanks

There’s no way to set a limit when instantiating the map, though I supposed you could have your own safe guard when accessing it. For example:

if (mymap.find(a) == mymap.end() and mymap.size() >= MAX_MAP_ALLOWED) {
    throw (runtime_error("map limit exceeded"));
} else {
    mymap[a] = b;
}

You could possibly create your own map class that encapsulates these checks.
