PROGRAM EXPLANATION

Algorithm and explanation

  1. Initialize the sample values used to work with a complex number.
  2. Apply complex and real to compute the required result.
  3. Display the result for work with a complex number and compare it with the documented sample output.

This example of work with a complex number computes the result directly from the prepared sample data. It demonstrates complex, real, and imag and prints a deterministic result that can be checked against the sample output.

DEBUGGING CHECKLIST

Common mistakes

Check this

For work with a complex number, keep the data shape and value types consistent with complex.

Check this

Apply complex in the same order shown by the algorithm; changing the order can change the result.

Check this

Verify the final complex and real result against the sample before trying new data.

Try it yourself

Practice: Run the program with the sample input, predict its output, and then test one boundary case of your own.
