You can place a file where you want. Use ifstream/ofstream/fstream (http://www.cplusplus.com/reference/iostream/ifstream/
http://www.cplusplus.com/reference/iostream/ofstream/
http://www.cplusplus.com/reference/iostream/fstream/) for that.

Code opening a file and printing it on the screen:

#include <iostream>
#include <fstream>
#include <string>
#include <algorithm>
#include <iterator>

using namespace std;


int main()
{
	string fname;
	cout << "Input the file name:" << endl;
	getline(cin, fname);

	cout << "---" << endl;
	ifstream fin(fname.c_str());
	if(!fin)
	{
		cout << "Can't open the file \"" << fname << "\"." << endl;
		return 1;
	}

	copy(istreambuf_iterator<char>(fin), istreambuf_iterator<char>(), ostreambuf_iterator<char>(cout));
	cout << endl << "---" << endl;

	if(!fin)
	{
		cout << "Error while writing to the file." << endl;
		fin.clear();
	}

	fin.close();
	if(!fin)
	{
		cout << "Can't close the file \"" << fname << "\"." << endl;
		return 1;
	}

	return 0;
}

i used the codes that syuf wrote like below(my text file name that i want to open is "test2")

#include <iostream>
#include <fstream>
#include <string>
#include <algorithm>
#include <iterator>

using namespace std;


int main()
{
	string fname;
	cout << "test2" << endl;
	getline(cin, fname);

	cout << "---" << endl;
	ifstream fin(fname.c_str());
	if(!fin)
	{
		cout << "Can't open the file \"" << fname << "\"." << endl;
		return 1;
	}

	copy(istreambuf_iterator<char>(fin), istreambuf_iterator<char>(), ostreambuf_iterator<char>(cout));
	cout << endl << "---" << endl;

	if(!fin)
	{
		cout << "Error while writing to the file." << endl;
		fin.clear();
	}

	fin.close();
	if(!fin)
	{
		cout << "Can't close the file \"" << fname << "\"." << endl;
		return 1;
	}

	return 0;
}

but it shows me the errors below:

Error: noname01.cpp(14,21):Could not find a match for 'std::getline(istream_withassign,std::basic_string<char,std::string_char_traits<char>,std::allocator<char>>)'
Error: noname01.cpp(24,26):Undefined symbol 'istreambuf_iterator'
Error: noname01.cpp(24,32):Expression syntax


what should i do know?
