#includeThis code creates a map to convert letter grades to GPAs. The keys are letter grades (characters) and the values are GPAs (doubles). The map is then populated with letter grade data, and a letter grade is chosen to be converted to a GPA using the map. The resulting GPA is printed to the console. Package library: C++ Standard Library. The TMap is a template class provided by the C++ Standard Library.#include
