Class containing Constants of std::string

Question

So I\'m currently working on a school-project with C++, which I\'m not really familiar with. I would like to create a class, containing all my constants (string,int,double,own c

In C++17, the recommended way of defining string constants if by using an inline constexpr std::string_view. Example:

namespace reference
{
    inline constexpr std::string_view deepSeaPath{R"(something)"};
    // ...
}

This is great because:

• std::string_view is a lightweight non-owning wrapper that can efficiently refer to string literals without any additional costs.

• std::string_view seamlessly interoperates with std::string.

• Defining the variables as inline prevents ODR issues.

• Defining the variables as constexpr makes it clear to both the compiler and other developers that these are constants known at compile-time.

If you do not have the luxury of using C++17, here's a C++11 solution: define your constants as constexpr const char* in a namespace:

namespace reference
{
    constexpr const char* deepSeaPath{R"(something)"};
    // ...
}
