Any advantage of using the s suffix in C++ [duplicate]

Question

My question is related to the use of the "s" suffix in C++?

Example of code using the "s" suffix:

auto hello = "Hello!"s; // a std::string 

The same could be written as:

auto hello = std::string{"Hello!"}; 

I was able to find online that the "s" suffix should be used to minimizes mistakes and to clarify our intentions in the code.

Therefore, is the use of the "s" suffix only meant for the reader of the code? Or are there others advantages to its use?

Answer 1

Null characters can be included in the raw string trivially; example from http://en.cppreference.com/w/cpp/string/basic_string/operator%22%22s

int main() {     using namespace std::string_literals;      std::string s1 = "abc\0\0def";     std::string s2 = "abc\0\0def"s;     std::cout << "s1: " << s1.size() << " \"" << s1 << "\"\n";     std::cout << "s2: " << s2.size() << " \"" << s2 << "\"\n"; } 

Possible output:

s1: 3 "abc" s2: 8 "abc^@^@def"
