QMapIn this example, we create a QMap object with string keys and integer values. We then call the constEnd() function to get a const-iterator pointing to the end of the map. This const-iterator can be used to traverse the map from the end to the beginning, but cannot modify the key-value pairs in the map. Package Library: Qt Librarymap = {{"apple", 3}, {"banana", 2}, {"orange", 4}}; QMap ::const_iterator iter = map.constEnd(); // iter will now point to the imaginary item past the last element in the map
