#include <iostream>
#include <fstream>
#include <string>
#include <vector>

using namespace std;

int main()
{
	vector<string> myvec;
	string line;

	cout<<"Line: ";
	getline(cin, line);
	myvec.push_back(line);

	ifstream file("whatever.txt")

	while(getline(file, line))
	{
		if(myvec[0] == line)
			cout<<"match"<< endl;
	}
}
