Thread: no match for 'operator<<' in.... Compile Problem!

Hi,

Just wondering if anyone can help me out in turning this program into a working program.

Basically, everything works, apart from inserting the results in the last SYSTEM() line.


Any help would be greatly appreciated.

Code:

#include <cstdlib>
#include <iostream>

using namespace std;



int main()
{
   string a;
   string b;
   string c;

   cout << "Enter source path (where files will be moved from)\n";
   cout << ": ";
   cin >> a;
   cout << "Enter destination path (where files will be moved to)\n";
   cout << ": ";
   cin >> b;
   cout << "Enter minimum access age in days\n";
   cout << "(This will move all files not accessed in x number of days)\n";
   cout << ": ";
   cin >> c;
   cout << c << a << b;

   system("robocopy //MOVE //MINLAD:" << c << a << b"");



   system("PAUSE");
   return EXIT_SUCCESS;
}

These also require you to #include the <string> header.

Code:

system("robocopy //MOVE //MINLAD:" << c << a << b"");

You can't do it like this. You'll likely need to use either a stringstream or sprintf to format the command.

Ah!

How would I go about doing this?

I'm pretty much a beginner in C++ and could do with all the help I can get.


Thanks.

Or more simply, just use + since they are all strings.

Code:

string d = "robocopy //MOVE //MINLAD:" + c + " " + a + " " + b;
system(d.c_str());
