COBOL Interview Question:
"Which file organization method is best for fast searching of records?"

Options:
A) Sequential
B) Indexed ✅ (Correct Answer)
C) Line Sequential
D) Random

Explanation:
➡ Sequential File Organization: Records are stored one after another, making searching slow because you have to read each record sequentially.
➡ Indexed File Organization: The best method for fast searching! 🔥 It allows direct access to records using an index, improving performance significantly.
➡ Line Sequential File Organization: Similar to sequential but used in text-based file processing.
➡ Random File Organization: Allows access using a unique key, but it’s not as optimized as indexed files for structured searches.

💡 Why Indexed Files?
Indexed file organization provides faster search capabilities by maintaining an index table. Instead of searching sequentially, COBOL can directly look up the index and retrieve the record quickly. 🚀
