Step-by-Step Solution
Solution:
Step 1: Identify data types to store
Name is string, age is number, favorite numbers is numeric array -- all different types.Step 2: Compare cell arrays and structures
Cell arrays hold mixed types but lack descriptive field names; structures organize data with named fields for clarity.Step 3: Choose best container for clarity and access
Structure allows accessing data by name (e.g., person.name), making it best for this case.Final Answer:
Use a structure to organize mixed data with named fields -> Option AQuick Check:
Named fields + mixed types = structure C [OK]
Quick Trick: Use structures for named mixed data, cells for unnamed [OK]
Common Mistakes:
- Choosing numeric arrays for mixed types
- Using character arrays for numbers
- Ignoring benefits of named fields in structures
