What is the difference between const and non-const references in C++?
An example of an AI chatbot conversation about const vs non-const references in C++.
What is the difference between const and non-const references in C++?
In C++, a const reference cannot modify the object it refers to, while a non-const reference can.
Can you give me an example of each?
Sure! For a const reference: const int& ref = x; where x is an int. For a non-const reference: int& ref = y; where y is an int.
What happens if I try to modify a const reference?
If you try to modify a const reference, you'll get a compilation error, as it is read-only.
When should I use const references?
Use const references when you want to pass large objects without copying them, while ensuring they remain unchanged.
