PROGRAM EXPLANATION

Algorithm and explanation

  1. Read the required input values.
  2. Store one pointer to the first character of each string literal and iterate over those pointers.
  3. Display the computed result.

Store one pointer to the first character of each string literal and iterate over those pointers.

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.
