A question I encoutered

[whyme]

Hi,

Is there anyone knows that how to store a series of strings? For example, there are different files names: "FileA.txt", "FileB.txt", etc. How to store these strings in order so that I can quote them later?

In C:

int main( )
{
  char const * const FileA = "FileA.txt";
  char const * const FileB = "FileB.txt";

  // Alternatively:
  
  char const * const File[2] = 
  {
    "FileA.txt",
    "FileB.txt"
  };
}

In C++:

#include <string>

int main( )
{
  std::string const FileA( "FileA.txt" );
  std::string const FileB( "FileB.txt" );

  // Alternatively:

  std::string const File[2] =
  {
    "FileA.txt",
    "FileB.txt"
  };
};

Thanks for your reply!

But the thing is I don't know how many files there are. Actually the whole program is about asking how many files firstly, and then combine all of them line by line. Therefore I think there need to be an array which each element can store a string, which is the name of each file.

You should probably use one of the dynamic containers for this. A Vector or List of std::strings would be the easiest to use if you have never done this before, but anyone of them should do given the parameters you've listed.
