APCSA Practice: What Does This Java Array Modify and Print Output? 💻

📢 What is the output of the following code?

java
Copy
int[] arr = {1, 2, 3, 4, 5};
for (int i = 0; i less than arr.length; i++) {
arr[i] *= 2;
}
System.out.println(arr[0] + " " + arr[1] + " " + arr[2] + " " + arr[3] + " " + arr[4]);
Options:
A) 2 4 6 8 10
B) 1 2 3 4 5
C) 2 3 4 5 6
D) 1 4 9 16 25

📝 Solution Breakdown:
1️⃣ The array arr is initialized with {1, 2, 3, 4, 5}.
2️⃣ The loop multiplies each element in the array by 2.
3️⃣ The modified array will be {2, 4, 6, 8, 10}.
🔥 Final Answer: Option A — 2 4 6 8 10
🔑 Key Takeaway:
The code multiplies each element of the array by 2 and prints the modified array.
