If you had the C code int a = -68, and you did a = a>>1 thirty three times, what would be the value of a? Explain why.
Explanation / Answer
Hi, as per chegg policy we are only allowed to solve the first 4 sub parts, please post others as separate question
1. 73 in binary is 1001001, you can verify by
1×2^6 + 0x2^5 + 0x2^4 + 1×2^3 + 0x2^2 + 0x2^1 + 1×2^0 = 73
2.similary 11101010 base 2 which is binary is 234 in decimal
3.5210 as unsigned(positive) in binary is - 1010001011010 &3410 is 110101010010
1010001011010
110101010010
adding, we get 010000110101100- which is 8620
4. 510 in binary is- 0111111110, 2410 is 0100101101010
multiplying we get 0100101100000100101100, which is 1229100
Thumbs up if this was helpful. otherwise let me know in comments. Good Day.
