PROGRAM EXPLANATION
Algorithm and explanation
- Read the required input values.
- Store each input at its array index, then visit the same indices to print the values.
- Display the computed result.
Store each input at its array index, then visit the same indices to print the values.

DEBUGGING CHECKLIST
Common mistakes
Check this
Use the correct format specifier for every variable.
Check this
Initialize variables before using their values.
Check this
Check braces, semicolons and input order carefully.
Try it yourself
Practice: Run the program with the sample input, predict its output, and then test one boundary case of your own.
