Basic Compound Assignment Operators

In this problem, you will create a program that reads an initial balance, an amount to add, and an amount to subtract from standard input, then uses compound assignment operators (+=, -=) to incrementally update the variable balance and displays the final balance.

Learning Objective: Understand how to use compound assignment operators (+=, -=)

Overview

Read three integers from standard input and use compound assignment operators to efficiently update the variable value.

Input Format

initial_balance
add_amount
subtract_amount

Specifications

• Use the first integer as the initial value of variable balance
• Add the second integer to balance using the += operator
• Subtract the third integer from balance using the -= operator
• Output the final balance

Output Format

Balance: <final_balance>

Sample Input/Output

Input:
1000
500
200

Output:
Balance: 1300
