Use string_view as a Lightweight String Object
Learn to use string_view as a lightweight string object.
We'll cover the following
The string_view
class provides a lightweight alternative to the string class. Instead of maintaining its own data store, string_view
operates on a view of a C-string. This makes string_view
smaller and more efficient than std::string
. It's useful in cases where we need a string object but don't need the more memory- and computation-intensive features of std::string
.
How to do it

class looks deceptively similar to the STL string
class, but it works a bit differently. Let's consider some examples:
Here's an STL
string
initialized from a C-string (array ofchar
