存储数据结构

我运行这个程序很好，但是每次我退出它并再次运行时，矩阵 data[] 中的所有数据都会丢失。有没有办法保留这些数据，以便当我再次运行它时可以检查它？（对不起，如果这个问题太简单了，我几周前就开始编码了）

#include <iostream>
#include <cstdlib>
#include <conio.h>
#include <cstdio>
#include <iomanip>
using namespace std;
const int TRUE = 1;
static int n = 0;

struct Restaurant{
    char name[30];
    char address[50];
    float price;
    char food[20];
};
Restaurant data[10];
void inputData(void);
void outputData(void);
    int main()
{
    char option;
    cout << "============Welcome to Restaurant Interface!============n" << endl;
    while(TRUE)
    {
        cout << "Type 'A' to add a restaurant data " << endl;
        cout << "     'S' to search for restaurants "<< endl;
        cout << "  or 'E' to exit" << endl;
        option = getch();
        switch (option)
        {
            case ('a'):
            case ('A'):             
                inputData();
                break;
            case ('s'):
            case ('S'):
                outputData();
                break;

                cout << "Thanks for using Restaurant Interface! See you soon mate!" << endl;
                exit(0);
            default:
                cout << "nInvalid option. please choose againn";

    cout << "Type the address of your restaurant: "; gets(data[n].address);
    cout << "Type the price range: "; gets(temp);
    data[n].price = atof(temp);
    cout << "Type the style of food: "; gets(data[n].food);;
    cout << "New restaurant data added successfully!!!" << endl;
    n++;    
}
void outputData()
{
    cout << "nn==============================================================nn";
    if(!n)
    {
        cout << "Empty list." << endl;
        return;
    }
    cout << "Restaurant list" << endl;
    cout << left << setw(20) << "Name";
    cout << left << setw(30) << "Address";
    cout << left << setw(15) << "Average Price";

    for (int i=0; i<n; i++)

    }
