Hello everybody, I am new here in this community and I hope to learn a lot from you guys and then maybe later become the one to give out advices. I am also new to programing and I recently started learning C++.
I am doing a program that is supposed to ask a user for a name of a file and count the lines from that file and print it out in another file and also to the screen.
I am supposed to use a function but I can´t use pointers, vectors, arrays because we have not covered that yet in the course.
My problem is that I can´t figure out how to actually count the lines and print it out to an output file and also to the screen.
Here is what I got so far.
#include <iostream>
#include <fstream>
#include <cstdlib>
#include <string>
using namespace std;
void countLines(ifstream& in_stream, ofstream& out_stream);
int main( )
{
using namespace std;
char in_file_name[16], out_file_name[16];
ifstream in_stream;
ofstream out_stream;
cout << "Enter the input file name (maximum of 15 characters):\n";
cin >> in_file_name;
cout << "Enter the output file name (maximum of 15 characters):\n";
cin >> out_file_name;
in_stream.open(in_file_name);
if (in_stream.fail( ))
{
cout << "Input file opening failed.\n";
exit(1);
}
out_stream.open(out_file_name);
if (out_stream.fail( ))
{
cout << "Output file opening failed.\n";
exit(1);
}
}
void countLines(ifstream& in_stream, ofstream& out_stream)
{
int count;
char next;
in_stream.get(next);
while (! in_stream.eof( ))
{
if (next == '\n')
out_stream << count++;
else
out_stream << next;
in_stream.get(next);
}
}Any help would be much appreciated.
