3. Given that a is an unsigned char, and is initialized to a=23, what is the result of b after each of the following code fragments? Assume that b is an unsigned char. Give the answer in decimal format b = a << 2; b = a / 7; b = a >> 4; b = a + 12;. Vî de + c b = -a; b = a - 29; b = a + 5; - b = a...
What number does each line of code print out? Briefly explain why. printf("%u\n",(unsigned char)(-2)); printf("%d\n",(unsigned char)(-2)); printf("%u\n",(uint16_t)(-2)); printf("%d\n",(uint16_t)(-2)); printf("%u\n",(unsigned int)(-2)); printf("%d\n",(unsigned int)(-2));
What are the values stored in the array a after the following code executes? int[] a = new int[10]; a[0] = 1; for (int i = 1; i < a.length; i++) a[i] = 2 * a[i - 1] - 1;
3a) Mathematically, what does the following snippet of RTL code do to the value stored in R1? In other words, if the contents of R1 are interpreted as a number, write a relationship between the values before and after this code executes. Ignore cases that overflow. Simplify your answer as much as possible. R2 = R1 OR 0 R2 = R2 SLA 2 R1 = R2-R1 3b) What would the result (in R1) be if the initial value (in R1)...
Consider the following code snippet. What will be stored in the list prices after this code executes? prices = [10.00, 15.50, 13.50, 20.15] for i in range(len(prices)) : prices[i] = prices[i] * 1.06 Group of answer choices [10.00, 15.50, 13.50, 20.15] [10.60, 16.43, 14.31, 21.36] [1.06, 1.06, 1.06, 1.06] [0.0, 0.0, 0.0, 0.0]
You are writing code to control 8 stage lights in the Performing Arts Center. You start by accessing an 8-bit unsigned char value through a pointer called register. This value is used to turn lights on (1) and off (0). The diagram below is the bit map of a sample value for the stage lights, but the actual value will differ. bit7 bit6 bit5 bit4 bit3 bit2 bit1 bit0 0 1 1 0 1 0 0 1 Your job is...
The unsigned decimal value (1,036)(base 10) is to be stored as a 16-bit word in memory. a. Show the 16-bit unsigned binary representation of (1,036)(base 10). b. Show the 4-digit unsigned hexadecimal representation of (1,036)(base 10). c. The unsigned binary value of part (a) should be stored using two bytes of a byte-addressable memory at locations 400 and 401. Specify the hexadecimal value in each byte for a “big endian” instruction set architecture. Give your answer by showing a table.
