I'm trying to learn using headers in C++. My sample code for the bank as follows

In following code, I just want to get a simple DepositTransaction and WithdrawTransaction class and have them inherit from base class called Transaction.

I started with the header file:

transaction.h

#ifndef TRANSACTION_H
#define TRANSACTION_H

#include <string>

class Transaction {
protected:
    std::string _customerId;
    std::string _tellerId;

public:
    Transaction(const std::string& customerId, const std::string& tellerId);

    std::string get_customer_id() const;
    std::string get_teller_id() const;

    virtual std::string get_transaction_description() const = 0;
};

class DepositTransaction : public Transaction {
private:
    double _amount;

public:
    DepositTransaction(const std::string& customerId, const std::string& tellerId, double amount);

    std::string get_transaction_description() const override;
};

class WithdrawTransaction : public Transaction {
private:
    double _amount;

public:
    WithdrawTransaction(const std::string& customerId, const std::string& tellerId, double amount);

    std::string get_transaction_description() const override;
};

#endif

Then the source file

transaction.cpp

#include "transaction.h"
#include <iostream>

Transaction::Transaction(const std::string& customerId, const std::string& tellerId)
    : _customerId(customerId), _tellerId(tellerId) {}

std::string Transaction::get_customer_id() const {
    return _customerId;
}

std::string Transaction::get_teller_id() const {
    return _tellerId;
}

DepositTransaction::DepositTransaction(const std::string& customerId, const std::string& tellerId, double amount)
    : Transaction(customerId, tellerId), _amount(amount) {}

std::string DepositTransaction::get_transaction_description() const {
    return "Deposit: " + std::to_string(_amount);
}

WithdrawTransaction::WithdrawTransaction(const std::string& customerId, const std::string& tellerId, double amount)
    : Transaction(customerId, tellerId), _amount(amount) {}

std::string WithdrawTransaction::get_transaction_description() const {
    return "Withdraw: " + std::to_string(_amount);
}

Finally, main.cpp

int main (){
    DepositTransaction deposit("12345", "Teller001", 1000);
    WithdrawTransaction withdraw("67890", "Teller002", 500);


    std::cout << deposit.get_customer_id() << std::endl;  
    std::cout << withdraw.get_teller_id() << std::endl;   

    std::cout << deposit.get_transaction_description() << std::endl;  
    std::cout << withdraw.get_transaction_description() << std::endl; 
}

But when running, I get the error

the prelaunchtask c/c++ g++ build active file terminated with exit code

Upon clicking "show errors", I get

no problems have been detected in the workspace

I tried to fix it according to this post here but no dice

    What are the exact commands you use for compilation? Forget vscode JSON for the moment, just write the compilation commands into the terminal. – Quimby Aug 07 '23 at 14:12

    `build active file` builds *one* file and you need to build two. – Yksisarvinen Aug 07 '23 at 14:14
  • This issue is explained in the official documentation here: [https://code.visualstudio.com/docs/cpp/config-mingw#_modifying-tasksjson](https://code.visualstudio.com/docs/cpp/config-mingw#_modifying-tasksjson) – drescherjm Aug 07 '23 at 14:19
  • [https://stackoverflow.com/a/73277441/487892](https://stackoverflow.com/a/73277441/487892) should have been the solution provided you are not using code-runner, CMakeTools or MakefileTools. If you need help with that you will need to copy and paste the exact build command from the terminal including any compiler messages. – drescherjm Aug 07 '23 at 14:22
