My program won't run in Dev C++.

[judo11]

This program runs very well in Visual C++ and I also want to run this program in Dev C++. How can I run this program using DEV C++?

#include<iostream>
#include<fstream>
#include<cstring>
using namespace std;

int main()
{
	string FileName;
	char UserInput[512];
	string ReadBuffer;
	
	cout<<"Please enter the name of the file to write to.\n";
	cout<<"File Name";
	cin>>FileName;
	cin.get();
	cout<<"Please enter a line of text to save to the file.\n";
	cout<<"Text: ";
	cin.getline(UserInput, 512);
	
	ofstream WriteToFile;
	WriteToFile.open(FileName);
	WriteToFile<<UserInput;
	WriteToFile.close();
	
	system("CLS");
	cout<<"Opening the file: "<< FileName <<", the contents of the file are:\n\n";
	
	ifstream ReadFromFile(FileName);
	if(ReadFromFile.is_open())
	{
		getline(ReadFromFile, ReadBuffer);
		cout<< ReadBuffer <<endl;
	}
	else
		cout<<"Failed to open the file!\n";
		
	cin.get();
	return 0;
}

You have to enable C++11.

[judo11]

C++11? How can I enable it sir?

[judo11]

I also want it to run in Cygwin.

[Peter87]

You have to pass the flag -std=c++11 to the compiler. I'm not sure exactly how to do that in Dev-C++. There might be a checkbox somewhere, or maybe you can add the compiler flag manually somehow.

Another option, since the compiler you're using may not support C++11, would be to use the c_str() function to convert the string to a C-string.

	ifstream ReadFromFile(FileName.c_str());
