    Application of union in C++.
    A union allows storing different data types in the same memory location.
    The size of the union is determined by the largest member.
    Here, we define a union named Converter that can hold either an int or a float.
    The union's size is the size of the largest member, which is float in this case.
    Accessing the members of a union is done through the same memory location,
    The last written member determines the value of the union.
    In this example, we write a float value and then read it as an int.
    This is a demonstration of how unions can be used to interpret the same memory in different ways.
    Note: Using unions requires caution as it can lead to undefined behavior if not used correctly.
    The union is a powerful feature in C++ that allows for memory-efficient data representation.
