I'm new to C++ programming. I'm trying to make a database that stores the information without overwrite it. I want this program to store the client’s selection in somewhere that doesn't change and also that creates a new storage for the new value any time the client enters a new selection instead of overwriting it. I did something like that in my code but any time the program runs again and the client enters a new selection, the client’s selection is overwritten with the new value. I don’t know if it’s possible to do that (store the client’s selection in somewhere where doesn't change) with C++. I've been reading and I think I can create a database for my program.
THIS IS MY CODE:
#include <iostream>
#include <string>
using namespace std;
// FUNCTIONS
void mainMenu();
void laptopsMenu();
void pcsMenu();
void tabletsMenu();
//Global Variables
string userOrder = ' ';
void main ()
{
string personType = ' ';
do
{
cout << 'Welcome to the Computer Store!' << endl << endl;
cout << 'Are you a client or manager?' << endl;
cin >> personType;
if ( personType 'client' )
{
mainMenu(); // Calls Function mainMenu
}
else if ( personType 'manager' )
{
cout << endl << 'The client ordered a ' << userOrder << '.'<< endl << endl;
}
}
while ( personType 'client' | personType 'manager' );
cout << endl << 'Thank you for your business. BYE !!! ' << endl;
system('pause');
}
