Assignment operator: Using Compound Assignment Operators

In this problem, you will create a program that calculates a game's final score by adding bonus points, subtracting a penalty, and applying a multiplier to an initial score, then displays the result to standard output.

Learning Objective: Understand how to write concise code using compound assignment operators (+=, -=, *=, /=)

Overview

Create a game score management system. Using compound assignment operators allows you to write "update variable value" operations more concisely.

Specifications

Receive the following values from standard input:

1. Initial score (integer)
2. Bonus points (integer)
3. Penalty points (integer)
4. Multiplier (integer)

Processing:

1. Add bonus points to score (use +=)
2. Subtract penalty points from score (use -=)
3. Multiply score by multiplier (use *=)

Output the final score in format "Final Score: [score]".

Input Example

100
50
20
2

Output Format

Final Score: 260

Calculation Example

• Initial: 100
• Add bonus: 100 + 50 = 150
• Subtract penalty: 150 - 20 = 130
• Apply multiplier: 130 × 2 = 260
