Hello, Space Explorer! Today, we’re going to discuss a practical and essential topic in C++: managing data using structures and classes. To practice this concept, we will build a simple Student Management System. Specifically, we will create a class that stores students and their grades. This hands-on approach will help us understand how structures and classes can be used effectively in real-world applications. Are you excited? Great, let's dive in!
To accomplish our task, we need to implement three primary methods within our class:
void add_student(std::string name, int grade)
: This method allows us to add a new student and their grade to our list. If the student is already on the list, their grade will be updated.std::optional<int> get_grade(std::string name)
: This method retrieves the grade for a student given their name. If the student is not found, it returnsstd::nullopt
.bool remove_student(std::string name)
: This method removes a student from the list by their name. It returnstrue
if the student was successfully removed andfalse
if the student does not exist.
Does that sound straightforward? Fantastic, let's break it down step-by-step.
