C++ Pointers and References
Summary and Overview
Congratulations on completing the C++ Pointers and Reference course! 🎉
Here is a summary of the key takeaways
References | Pointers | |
---|---|---|
Syntax | Declared using & symbol. | Declared using * symbol. |
Initialization | Must be initialized upon declaration. | Can be initialized later or left uninitialized. |
Nullability | Cannot be null. | Can be null. |
Address | No separate address operator needed. | Requires the address-of operator (&). |
Reassignment | Cannot be reassigned to refer to another object. | Can be reassigned to point to different objects. |
Memory Management | No explicit memory management required. | Requires explicit allocation and deallocation. |
Syntax for Access | Use the same syntax as the object it refers to. | Dereferencing using * and accessing using ->. |
Size in Memory | Generally takes the same amount of memory as the object it refers to. | Takes up its own memory space to store the address. |
Function Arguments | Used for passing arguments by reference. | Used for passing arguments by value or reference. |
Use in Arrays | Cannot be used to iterate over an array. | Can be used to iterate over an array. |
