This project implements a mathematical calculation function in C that processes a range of integers to find the average of those divisible by 3.

1. Input: Two integers (num1, num2).
2. Range Definition: Determines the range between the smaller and larger number (exclusive).
3. Filtration: Selects numbers where x % 3 == 0.
4. Calculation: $\text{Average} = \frac{\sum \text{Selected Numbers}}{\text{Count}}$

Based on Question 2: Input: 4 and 15

• Range: $5, 6, 7, ..., 14$
• Multiples of 3 found: $6, 9, 12$
• Sum: $6 + 9 + 12 = 27$
• Count: $3$
• Result: $27 / 3 = 9$
