C++ Program To Read And Display File Line By Line Using File Handling

Problem:- C++ program to read and display text file line by line or c++ program to display the contents of a text file or c++ display text file on screen or c++ program to create a file and display its contents or write a c++ program to display the contents of a file in reverse order or c++ read text file line by line or c++ print contents of file or write a c++ program which copies one file to another
c program to display the contents of a file on the screen or c++ read text file line by line.


Explanation:- First we have to create a file with extension (like .txt) after that by using the program we have to print the file in console screen. Always remember we have to read the file by line by line and also write the file line by line in console screen and one more thing file should be in the same folder in which our program already exists. We can give the file name in console screen so no need to give the filename in a program.


Solution:-

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

int main(int argc, char *argv[])
{
  ifstream in;
  char filename[20];

cout<<"Enter The File Name With Extension\n";
cin>>filename;

in.open(filename);

/*Here You Have To Create A File And put some data on it. 
Then Save the with Any Extension With File Name As Above Shown */

  if(!in) 
  {
    cout << "Cannot Open File. Or File Not Find\n";
    return 1;
  }

  char str[1000];

cout<<"\nFile is Given Below\n\n";
cout<<"\n============================================================\n\n";
  
  while(in) 
  {
    in.getline(str, 1000);
    if(in) 
cout << str << endl;
  }

cout<<"\n\n============================================================\n";
  in.close();

  return 0;
}
