Hi!
I am quite new at programing. I want to write a program that reads a textfile and then prints the content on the screen 25 rows at the time. I have read quite much about ifstream and ofstream. I wrote this program to count the lines in a file. And I was thinking that if I count the number of lines in a file I would be able to print the lines to the screen until there are no more lines in the file.
#include <iostream>
#include <fstream>
using namespace std;
int main()
{
ifstream in; // Detta är en inström som kopplas till en fil.
char rad[200]; // Buffer för en rad med tecken
char filnamn[50]; // Filensnamn.
int antalrader=0;
cout << "Ange filens namn ? ";
cin.getline(filnamn,50);
// Öppnar filen med det namn som användaren angivit.
in.open(filnamn);
// Testar om det inte gick att öppna filen.
if(!in.good())
{
cout << "Det gick ej att oppna filen " << filnamn << endl;
return 0;
}
// Så länge inte filslut hittats
while(!in.eof())
{
in.getline(rad,200);
antalrader++
}
in.close();
cout << "Filen " << filnamn << " innehåller " << antalrader << " rader" << endl;
return 0;
}Another idea was to put some kind of counter in a while-loop.
while(!file.eof())
{
std::string str;
getline(file,str);
std::cout << str << std::flush;
std::cin.get();
}The thing is that I am not that great learning from reading. Any help would great. It is one thing to know how to print a whole file to the screen but another to print some lines at the time.
I also wonder is I can use the manipulator noskipws to make sure all the spaces get copied.
