Unlock the Power of C Programming: Calculating Time Period Differences

Getting Started with Structures and Functions

When working with time-based applications, calculating the difference between two time periods is a crucial task. In C programming, achieving this requires a solid understanding of user-defined functions, structures, and pointers. If you’re familiar with these concepts, you’re ready to dive into a practical example that showcases their combined power.

The Program: Calculating Time Period Differences

In this program, we ask the user to input two time periods, which are then stored in structure variables startTime and stopTime, respectively. The differenceBetweenTimePeriod() function takes these variables as arguments and calculates the difference between the two time periods.

The Magic Happens: Call by Reference Technique

What makes this program efficient is the use of the call by reference technique, which allows the differenceBetweenTimePeriod() function to modify the original variables without returning any values. This approach enables seamless communication between functions, making the program more concise and effective.

Code Breakdown: Understanding the Logic

Let’s dissect the code to understand how it works:

• The user inputs two time periods, which are stored in startTime and stopTime structures.
• The differenceBetweenTimePeriod() function is called, passing startTime and stopTime as arguments.
• Within the function, the difference between the two time periods is calculated using pointer arithmetic.
• The result is displayed directly from the main() function, without the need for a return statement.

By mastering this program, you’ll gain a deeper understanding of how to leverage C programming concepts to tackle real-world problems. So, get coding and unlock the full potential of your applications!
