Convert command line argument to string

You can create an std::string

#include <string>
#include <vector>
int main(int argc, char *argv[])
{
  // check if there is more than one argument and use the second one
  //  (the first argument is the executable)
  if (argc > 1)
  {
    std::string arg1(argv[1]);
    // do stuff with arg1
  }

  // Or, copy all arguments into a container of strings
  std::vector<std::string> allArgs(argv, argv + argc);
}

No need to upvote this. It would have been cool if Benjamin Lindley made his one-liner comment an answer, but since he hasn't, here goes:

std::vector<std::string> argList(argv, argv + argc);

If you don't want to include argv[0] so you don't need to deal with the executable's location, just increment the pointer by one:

std::vector<std::string> argList(argv + 1, argv + argc);

It's already an array of C-style strings:

#include <iostream>
#include <string>
#include <vector>


int main(int argc, char *argv[]) // Don't forget first integral argument 'argc'
{
  std::string current_exec_name = argv[0]; // Name of the current exec program
  std::vector<std::string> all_args;

  if (argc > 1) {
    all_args.assign(argv + 1, argv + argc);
  }
}

Argument argc is count of arguments plus the current exec file.
