Vector Of Maps C

The original code uses a hand code linked list for the sparse part of the matrix.

Vector of maps c. We shall map this object model to our vector of map of map. Garage is the vector and car is the outer map and each property of a car is stored in inner map. You are creating a vector of collections and makepair is used to create a single element of the map collection. If you dont need a vector of collections and instead just a collection just use mapint bool.

510 82 96 now let us assume a map of string keys and integer values. That was mostly humour but since you took it seriously. Map in stl maps are associative containers that store elements in a mapped fashion. A map is a collection.

Vector in stl vector is same as dynamic arrays with the ability to resize itself automatically when an element is inserted or deleted with their storage being handled automatically by the container. Even if the map of vectors is maybe more natural to think of at first the multimap leads to simpler code as soon as we need to iterate over the data. Im trying to optimise some code that does some heavy work with sparse matrix. Each element has a key value and a mapped value.

Instead you should be inserting a map. Map of vectors in c stl with examples. This advantage of the multimap come from the fact that it is not a nested structure contrary to the map of vector. To store these we need a vector of integer paired with an integer.

Map of vectors or multimap.
