#include <iostream>

#include <iomanip>

#include <fstream>

#include <string>

using namespace std;

const char inFileName[] = "inputfile.txt";

const char outFileName[] = "output.txt";

ifstream inFile;

ofstream outFile;

int main() {

string line;

string temp;

inFile.open(inFileName); //open file

if (!inFile) { //check if u opened file properly or not

cout << "Error opening " << inFileName << " " << endl;

return 1;

}

outFile.open(outFileName); //open file

if (!outFile) { //check if u opened file properly or not

cout << "Error opening " << outFileName << " " << endl;

return 1;

}

int check = 0;

cin >> check;

while (getline(inFile, line)) {

outFile << line << endl;

}

outFile << endl;

inFile.close();

inFile.open(inFileName); //open file

if (!inFile) { //check if u opened file properly or not

cout << "Error opening " << inFileName << " " << endl;

return 1;

}

while (getline(inFile, line)) {

if (check < line.length()) {

outFile << line.substr(check, line.length()) << endl;
