What is the difference between a reference parameter and a const reference parameter?

When you use use ‘normal’ parameter, you pass the parameter by value and hence creating a copy of the parameter you pass. If you are using const reference, you pass it by reference and the original data is not copied. In both cases, the original data cannot be modified from inside the function.
