Utilities

1. Number Range Generator (loops)

Generates a sequence of numbers starting from a user-specified value.

Features:

• Input validation and overflow protection
• Configurable range (default: 16 numbers)
• Professional error handling

Usage:

./bin/loops
Enter starting number: 10

2. Mathematical Tables Generator (tables)

Creates formatted tables showing numbers, squares, cubes, and square roots.

Features:

• Customizable range (1-100)
• Formatted table output
• Mathematical calculations with proper data types
• Input validation

Usage:

./bin/tables
Enter lower limit (1-100): 1
Enter upper limit (1-100): 10

3. Days to Weeks Converter (conversion)

Converts days to weeks and remaining days with proper pluralization.

Features:

• Interactive conversion loop
• Proper pluralization handling
• Overflow protection
• Decimal week calculation

Usage:

./bin/conversion
Enter number of days (positive to convert, 0 or negative to quit): 14

Examples

Loops Output

=== Number Range Generator ===
Author: Jaden Mardini

Enter starting number: 5

Numbers from 5 to 21:
------------------------
5
6
7
...
21
------------------------
Total numbers: 17

Tables Output

=== Mathematical Tables Generator ===
Author: Jaden Mardini

Enter lower limit (1-100): 1
Enter upper limit (1-100): 5

+-----+----------+----------+---------+
| Num |  Square  |   Cube   |  Sqrt   |
+-----+----------+----------+---------+
|   1 |        1 |        1 |    1.00 |
|   2 |        4 |        8 |    1.41 |
|   3 |        9 |       27 |    1.73 |
|   4 |       16 |       64 |    2.00 |
|   5 |       25 |      125 |    2.24 |

Conversion Output

=== Days to Weeks Converter ===
Author: Jaden Mardini

Enter number of days (positive to convert, 0 or negative to quit): 14

Conversion Result:
-----------------
14 days = 2 weeks and 0 days
That's approximately 2.00 weeks total
