C plus plus code of mobile billing system?

Answer 1

Creating a mobile billing system in C++ involves designing classes to manage user accounts, billing transactions, and payment processing. You would typically define a User class to store user information and a Billing class to handle billing logic. Here's a simplified snippet:

class User {
public:
    std::string name;
    double balance;
    
    User(std::string userName, double initialBalance) : name(userName), balance(initialBalance) {}
};

class Billing {
public:
    void charge(User& user, double amount) {
        if (user.balance >= amount) {
            user.balance -= amount;
            std::cout << "Charged " << amount << " to " << user.name << ". Remaining balance: " << user.balance << std::endl;
        } else {
            std::cout << "Insufficient balance for " << user.name << std::endl;
        }
    }
};

This code defines basic functionality for a mobile billing system, allowing for user account management and transaction processing.
