Introduction

In the realm of software development, attention to detail is paramount. A single typo or minor error can have far-reaching consequences, affecting not only the functionality of the code but also its maintainability and readability. In this article, we will delve into a specific issue related to the overloaded postfix operator++ for Employee::Role, where a minor typo in the exception message can have significant implications.

The Issue: A Typo in the Exception Message

When implementing the default case of the overloaded postfix operator++ for Employee::Role, a crucial aspect to consider is the exception message. This message is displayed when an invalid or unknown role is encountered. However, in the provided code snippet, a typo is present in the exception message, reading "Unknown rolee" instead of the correct "Unknown role".

Employee::Role operator++(Employee::Role& role, int) {
    switch (role) {
        case Employee::Role::Intern: return role = Employee::Role::Junior;
        case Employee::Role::Junior: return role = Employee::Role::Middle;
        case Employee::Role::Middle: return role = Employee::Role::Senior;
        case Employee::Role::Senior: return role;  
        default: throw std::invalid_argument("Unknown rolee");
    }       
}

The Consequences of a Minor Typo

At first glance, a typo in the exception message may seem insignificant. However, this minor error can have far-reaching consequences, including:

Confusion and Misinterpretation: A typo in the exception message can lead to confusion and misinterpretation of the error, making it challenging for developers to diagnose and resolve the issue.
Reduced Code Quality: A minor typo can indicate a lack of attention to detail, which can negatively impact the overall quality of the code.
Increased Debugging Time: When a typo is present in the exception message, developers may spend more time debugging the issue, which can lead to increased frustration and decreased productivity.

The Fix: Correcting the Exception Message

To rectify the issue, the exception message should be corrected to read "Unknown role". This simple change can have a significant impact on the overall quality and maintainability of the code.

Employee::Role operator++(Employee::Role& role, int) {
    switch (role) {
        case Employee::Role::Intern: return role = Employee::Role::Junior;
        case Employee::Role::Junior: return role = Employee::Role::Middle;
        case Employee::Role::Middle: return role = Employee::Role::Senior;
        case Employee::Role::Senior: return role;  
        default: throw std::invalid_argument("Unknown role");
    }       
}

Best Practices for Exception Messages

When implementing exception messages, it is essential to follow best practices to ensure that the messages are clear, concise, and informative. Some key considerations include:

Use Clear and Concise Language: Exception messages should be written in a clear and concise manner, avoiding ambiguity and confusion.
Provide Relevant Information: Exception messages should provide relevant information about the error, including the cause and potential solutions.
Avoid Jargon and Technical Terms: Exception messages should be written in a way that is accessible to developers of all skill levels, avoiding jargon and technical terms.
