//this are the code for username and password but idk how to combine it together.
#include <iostream>
#include <string>
using namespace std;

int main(){
string username;
string password;
bool loginSuccess = false;

cout << "\tWelcome User. Please Enter Your Username And Password\n\n";

do{
cout << "Username: ";
cin >> username;
cout << "Password: ";
cin >> password;

if(username == "Username" && password == "Password"){

cout << "\nSuccessful Login\n\n";
loginSuccess = true;
}

else{
cout << "\nInccorrect username password\n";
cout << "Please try to login again.\n";
cout << endl;
}

}while(!loginSuccess);

system("pause");
return 0;
}
