What is the correct answer for following assignment operations?             int a = 10;             int c = 15;             c %= a ;             System.out.println("c %= a  = " + c );              c <<= 2 ;             System.out.println("c <<= 2 = " + c );              c >>= 2 ;             System.out.println("c >>= 2 = " + c );              c >>= 2 ;             System.out.println("c >>= 2 = " + c );

The given code is in Java language and it is performing various assignment operations. Let's break it down:

1. int a = 10; and int c = 15; - These lines are initializing two integer variables, a and c, with values 10 and 15 respectively.

2. c %= a; - This line is performing a modulus assignment operation. It is equivalent to c = c % a;. The % operator returns the remainder of the division of c by a. So, c % a is 15 % 10 which equals 5. So, after this line, c becomes 5.

3. System.out.println("c %= a = " + c ); - This line will print c %= a = 5.

4. c <<= 2; - This line is performing a left shift assignment operation. It is equivalent to c = c << 2;. The << operator shifts the bits of c two places to the left. So, c << 2 is 5 << 2 which equals 20. So, after this line, c becomes 20.

5. System.out.println("c <<= 2 = " + c ); - This line will print c <<= 2 = 20.

6. c >>= 2; - This line is performing a right shift assignment operation. It is equivalent to c = c >> 2;. The >> operator shifts the bits of c two places to the right. So, c >> 2 is 20 >> 2 which equals 5. So, after this line, c becomes 5.

7. System.out.println("c >>= 2 = " + c ); - This line will print c >>= 2 = 5.

8. c >>= 2; - This line is again performing a right shift assignment operation. So, c >> 2 is 5 >> 2 which equals 1. So, after this line, c becomes 1.

9. System.out.println("c >>= 2 = " + c ); - This line will print c >>= 2 = 1.

So, the correct answers for the assignment operations are 5, 20, 5, and 1 respectively.
