Unlocking the Power of C++: A Deeper Look at Structures and Functions
When it comes to mastering C++ programming, understanding structures and functions is crucial. If you’re familiar with C++ structures, structure and function, and pointers to structure, you’re ready to take your skills to the next level.
The Program: Calculating Time Differences
Let’s dive into a practical example that showcases the capabilities of C++ structures and functions. Imagine a program that calculates the difference between two time periods. The user is prompted to input two time periods, which are then stored in structure variables t1 and t2, respectively.
The Magic of computeTimeDifference()
The computeTimeDifference() function is where the real magic happens. This function takes the two time periods as input and calculates their difference. But here’s the twist – it doesn’t return the result. Instead, it uses call by reference to display the output directly from the main() function.
A Closer Look at the Code
The program’s logic is straightforward. The user inputs two time periods, which are stored in t1 and t2. The computeTimeDifference() function is called, passing t1 and t2 as arguments. The function calculates the difference and displays the result without returning it.
What’s Next?
Now that you’ve seen how C++ structures and functions can be used to calculate time differences, it’s time to take your skills further. Explore other applications of structures and functions, such as using difftime() to calculate time intervals. The possibilities are endless!
