#includeIn this example, a `QList` is created to store `QString` values, then three fruits are added to the list using the `<<` operator. The `reserve` method is used to allocate memory for three `QString` values. The `end` method is called to get an iterator pointing to the past-the-end element of the list. The `back` method is used twice to get the last fruit in the list before and after decrementing the end iterator. The `QList` class is part of the QtCore library. Overall, the QList class is a useful tool for managing dynamic arrays of data in C++ and is part of the Qt library.#include int main() { QList list; list.reserve(3); list << "apple" << "banana" << "cherry"; QString lastFruit = list.back(); list.end()--; QString newLastFruit = list.back(); }
