What are some examples of string literals in C++17?

In C++17, string literals can be used in various forms, such as raw string literals and UTF-8 string literals. For example:

1. Regular string literal: "Hello, World!"
2. Raw string literal: R"(This is a raw string)"
3. UTF-8 string literal: u8"Hello, UTF-8!".

Can you explain raw string literals in more detail?

Sure! Raw string literals allow you to include characters without needing to escape them. They start with R followed by a delimiter, and end with the same delimiter. For example, R"(Hello, World!)" preserves the newline character.

What are the benefits of using UTF-8 string literals?

UTF-8 string literals, denoted by u8, allow you to represent Unicode characters directly in your code. This is beneficial for internationalization, as it supports a wide range of characters from different languages.

Are there any limitations to using string literals in C++17?

Yes, one limitation is that raw string literals cannot contain the delimiter sequence within them. Additionally, while UTF-8 literals are convenient, they may require proper handling when interfacing with APIs expecting different encodings.
