Question

looking for a UML diagram for this program in cpp

a. Member variables and member functions b. Access specifiers for all member variables and member functions C. Data types for all member variables d. Data types for all parameters e. Return types for all member functions, constructors, and destructors class Account { private: double balance; // Account balance double interest Rate; // Interest rate for the period double interest; // Interest earned for the period int transactions; // Number of transactions public: Account (double iRate = 0.045, double bal = 0) { balance = bal; interest Rate = iRate; interest = 0; transactions = 0; } void set InterestRate(double iRate) { interest Rate = 1Rate; } void makeDeposit(double amount) { balance += amount; transactions ;) bool withdraw( double amount); // Defined in Account.cpp void calcInterest() { interest = balance interest Rate; balance + interest; } double getInterestRate() const { return interest Rate; ) double getBalance() const { return balance; } double get Interest() const { return interest; ) int getTransactions() const { return transactions; } };

Answer 1

The question describes creating a UML class diagram. A class diagram consists of the static view of the class with the variable names, their access specifiers, and all the functions of the class in a single block. It also represents the relationship between different classes.

Here, only one class is described. So the class diagram will be for only one class.

The class diagram of the class Account is shown below -

Account balance: double - interestRate: double - interest: double - transactions: int + Account(iRate: double, bal: double) + setInterestRate(iRate: double) + makeDeposit(amount: double) + withdraw(amount: double): bool + calcInterest() + getinterestRate() const: double + getBalance() const: double + getInterest() const: double + getTransactional) const: int

The explanation of the class diagram is as follows-

• The top section is the class name, Account
• The next section lists all the member variables of the class.
• The next and last section consists of all the functions of the class.

The + /- sign before each line indicates the access specifier. + is for public access specifier. - is for private access specifier.

The order of variables in a UML diagram is - <access_specifier> <var_name>:<data_type>

The order of functions in a UML diagram is - <access_specifier> <func_name> : <return type>. If no return type(void), then nothing is mentioned.
