#include<iostream>

using namespace std;

struct old_car{
     string model;
     string make;
     string year;
     double price;
};

struct new_car{
     string model;
     string make;
     string year;
     double price;
     double new_price;
};

int main(){

    old_car old[100];
    new_car newdata[100];  
    ifstream fin;
    fin.open("olddata.txt"); //Assuming data is in olddata.txt
   
    int count = 0;
    while (fin >> old[count].model >> old[count].make >> old[count].year >> old[count].price){
         count++;
    }
    for (int i = 0; i<count; i++){
        newdata[i].model = old[i].model;
        newdata[i].make = old[i].make;
        newdata[i].year = old[i].year;
        newdata[i].price = old[i].price;
        newdata[i].new_price = old[i].price + 0.08 * old[i].price;
    }
    for (int i = 0; i<count; i++){
