- * 3. READ INPUT: Use fgets() to read the user's input as a generic string (char array).
- * This allows the program to accept multi-digit numbers (e.g., "-500") or the command ('n').
- * 4. TERMINATION CHECK: Immediately check if the input string is exactly "n" using strcmp().
- * If true, the user wants to quit, so break the loop.
- * 5. VALIDATION & CONVERSION: If the input is not "n", use sscanf() to safely attempt to convert
- * the string into an integer.
- * 6. COUNTING LOGIC: If sscanf() successfully reads an integer (sscanf returns 1):
- * - If the number is > 0, increment positive_count.
- * - If the number is < 0, increment negative_count.
- * - If the number is == 0, increment zero_count.
- * 7. ERROR HANDLING: If the input is neither "n" nor a valid number (sscanf returns 0),
- * inform the user of invalid input and continue the loop.
- * 8. FINAL DISPLAY: After the loop terminates, print the final totals for positive, negative, and zero counts.
