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

int acc(int x)
{
    return (10*x);
}

int main()
{
      //reading 9 items from file, assume the file has upto 9 items
    int array[3][3];

    ifstream inputFile("afile.txt");  //ive not checked if the file exists
    ofstream outputFile("output.txt");

    //read from file
    int a;
    for(int i = 0; i < 3; i++)
    {
        for(int j = 0; j < 3; j++)
        {
            inputFile>>a;
            array[i][j] = acc(a);
        }
    }

    //print to file
    for(int i = 0; i < 3; ++i)
    {
        for(int j = 0; j < 3; ++j)
        {
        	if(j%3== 0)
        	cout<<endl;
        	cout<<array[i][j];
        	outputFile<<array[i][j];
        }
