What are some examples of using 'const' in C++?

In C++, 'const' is used to define constants. For example, you can declare a constant variable like this: 'const int x = 10;'. This means that the value of x cannot be changed.

Can you give me more examples of 'const' in function parameters?

Sure! You can use 'const' in function parameters to prevent modification. For instance, 'void printValue(const int value)' ensures that 'value' cannot be altered within the function.

What about using 'const' with pointers?

Great question! You can have 'const' pointers, like 'const int* ptr', which means the pointer can change, but the value it points to cannot. Alternatively, 'int* const ptr' means the value can change, but the pointer itself cannot.

Are there any best practices for using 'const'?

Yes! It's best to use 'const' whenever possible to make your code safer and clearer. It helps prevent accidental changes to variables and improves code readability.
