How to user input using "cin" while using composition in C++ - c++

Question

I have three C++ class, InventoryItem, SalesPerson and Transaction. I am using composition to use InventoryItem and SalesPerson class in Transaction. I want to use user input instead of just passing values in constructor, but I am not being able to do it. Any help will be highly appreciated. Following is my C++ file.
#include<iostream>
#include<string>
using namespace std;
class InventoryItem {
private:
int stockNum; double price;
public:
InventoryItem(int, double);
void display(); };
InventoryItem::InventoryItem(int stkNum, double pr) {
stockNum = stkNum;
price = pr;
}
void InventoryItem::display() {
cout << "Item #" << stockNum << " costs $" << price << endl;
}
//SalesPerson class
class Salesperson {
private:
int idNum;
string name; public:
Salesperson(int, string); void display();
};
Salesperson::Salesperson(int id, string lastName) {
idNum = id;
name = lastName;
}
void Salesperson::display() {
cout << "Salesperson #" << idNum << " " << name << endl;
}
//Transaction(main class)
class Transaction {
private:
int transNum;
InventoryItem itemSold;
Salesperson seller;
public:
Transaction(int, int, double, int, string);
void display();
};
Transaction::Transaction(int num, int item, double pr,
int salesId, string name) : itemSold(item, pr),
seller(salesId, name) {
transNum = num;
}
void Transaction::display() {
cout << "Data for transaction #" << transNum << endl; itemSold.display();
seller.display();
}
int main() {
Transaction aSale(247, 782, 44.77, 512, "Richardson"); aSale.display();
return 0;
}

I am posting this as an answer instead of comment, because i dont have backticks on my phone. So you want to do something like
int main()
{
int x, y, z;
double f;
string name;
cin >> x >> y >> f >> z >> name;
Transaction(x, y, f, z, name);
return 0;
}
Of course you can divide the cin line into one cin per variable and cout instructions on what a user must input next. This would look like this
int main()
{
int x, y, z;
double f;
string name;
cout << "Enter x: ";
cin >> x;
cout << "Enter y: ";
cin >> y;
cout << "Enter f: ";
cin >> f;
cout << "Enter z: ";
cin >> z;
cout << "Enter name: ";
cin >> name;
Transaction(x, y, f, z, name);
return 0;
}
Substitute strings in cout lines with strings you want to prompt the user with.
