FFWD to 2019. Although this code worketh in 2011 too.

// g++ prog.cc -Wall -std=c++11
#include 
#include 

 using namespace std;

 template
    inline 
      constexpr /* compile time */
      array string_literal_to_array ( char const (&charrar)[N] )
 {
    return std::to_array( charrar) ;
 }

 template
    inline 
      /* run time */
      vector string_literal_to_vector ( char const (&charrar)[N] )
 {
    return { charrar, charrar + N };
 }


int main()
{
   constexpr auto arr = string_literal_to_array("Compile Time");
   auto cv = string_literal_to_vector ("Run Time") ;
   return 42;
}

Advice: try optimizing the use of std::string. For char buffering std::array is the fastest, std::vector is faster.
