Working with String Manipulation

The file is a simple C++ program that utilizes the Standard Template Library (STL) to create and manage a map data structure. Here's a breakdown of its components: 1. **Includes and Namespace**: - The program includes the necessary headers: `<iostream>` for input and output operations, `<string>` for string manipulations, and `<map>` for the map data structure. - It also uses the `std` namespace to avoid prefixing the standard library types and functions with `std::`. 2. **Main Function**: - The `main()` function initializes a `map<int, string>` called `topFilms`, which will hold pairs of integers (as keys) and strings (as values). In this case, the integers represent the ranking of films. 3. **Adding Elements**: - The program explicitly initializes three entries in the map using the bracket notation: - `1` corresponds to "Gone with the Wind" - `2` corresponds to "Citizen Kane" - `3` corresponds to "Vertigo" - It then adds another entry for the film "The Godfather" with the key `4`, using both the `insert` method and the list initialization approach. 4. **Output**: - The program outputs the total number of films in the map using `topF()` and then iterates through the map to print each film's ranking and title using an iterator. 5. **Error**: - It contains a small typo in the for loop where `topF()` should be `topF()`, which would result in a compilation error. 6. **Return Statement**: - The program returns `0`, indicating successful execution. Overall, this C++ program is a basic demonstration of how to use a map to store and display a list of top ranked films.
