2. Write a C program that treats A1A0, A3A2, and A5A4 as three 2-bit unsigned binarynumber. The program should output the sum of those three numbers onto B. Use shift on A inputto position each bit pattern for generating sum. Therefore exampleASnap = A;A5A4 = (ASnap >> 4) & 0x03; // 2 bits are either 0,1,2, or 3and Sum = A5A4 + A3A2 + A1A0;
