Input File to Output File
I am making a program that reads from a .txt file and outputs the names that are in my .txt file into an output file that the user specifies. My program compiles but then I get an error that says
"int main(): Assertion `fin.is_open()' failed.
Aborted"
What am I doing wrong
Code:
#include <iostream>
#include <fstream>
#include <string>
#include <cassert>
#include <cfloat>
using namespace std;
int main()
{
cout << "Enter the name of the input file:";
string inputname;
getline(cin, inputname);
ifstream fin;
fin.open(inputname.data());
assert ( fin.is_open() );
int count=0;
double reading,
sum=0.0;
for(;;)
{
fin >> reading;
if (fin.eof()) break;
count++;
}
fin.close();
cout << "Enter name of output file:";
string outputname;
getline(cin, outputname);
ofstream fout(outputname.data());
assert(fout.is_open());
fout << "There are " << count << " numbers.";
fout.close();
cout << "Finished!\n";
}
