Simple Program Book Entry Using structure Variable in C++ Programming
How It Works
Here is a step-by-step walkthrough of how the C++ program for Structure and Union In C++ runs, line by line. Following the flow of the code makes it clear how each statement contributes to the final result:
Key points to remember:
- Read the code top to bottom and match each line to the output it produces.
- Compile and run the example yourself rather than only reading it.
- Modify one statement at a time so you can see exactly what each change does.
After running it, compare your console output with the Sample Output above to confirm the program behaves as expected. Try changing the values and re-running the program to see how the result changes — experimenting with small edits is the fastest way to understand the logic and to remember the C++ syntax used in this example.
