C++ supports both Object-Oriented Programming (OOP) and Procedural Programming. The main differences between them are as follows:

1. Abstract: Object-oriented programming emphasizes abstracting real-world problems into objects, defining relationships and behaviors between them to solve problems. In contrast, procedural programming focuses on breaking problems down into a series of steps and solving them by executing these steps sequentially.
2. Encapsulation: Object-oriented programming combines data and operations together to create the concept of classes, achieving data hiding and protection. On the other hand, procedural programming does not provide the encapsulation feature for data, allowing direct access and modification.
3. Inheritance: Object-oriented programming allows for the creation of new objects through inheritance, enabling the reuse of existing code and behaviors. In contrast, procedural programming does not include the concept of inheritance, as each procedure is independent.
4. Polymorphism refers to the ability in object-oriented programming for the same operation to behave differently depending on the object. This flexibility is difficult to achieve in procedural programming.
5. Code reuse in object-oriented programming is achieved through inheritance, composition, and other means, reducing the need for repetitive coding. In contrast, procedural programming lacks such mechanisms, requiring manual implementation for code reuse.

In general, object-oriented programming focuses more on modeling and abstracting the real world, providing a more flexible and scalable programming approach through features such as encapsulation, inheritance, and polymorphism. On the other hand, procedural programming is simpler and more intuitive, suitable for solving simple problems or scenarios requiring high efficiency.
