[SOLVED] plz tell me the output of the following

Question

public class Program {
public static void main(String[] args) {
int num1 = 4;
int num2 =8;
num2 += ++ num1;

System.out.println(num2);
}
}

Answer 1

++num1 increments num1 and returns the result (4 + 1 = 5).

num2 += ++num1 => num2 += 5
num2 += 5 => num2 = num2 + 5 = 8 + 5 = 13

Hence, 13 is printed.
