Convert command line argument to string

Question

I have a program that reads hard-coded file-path and I want to make it read file-path from command line instead. For that purpose I changed the code like this:

#         


        

Answer 1

You can create an std::string

#include 
#include 
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 allArgs(argv, argv + argc);
}
