(Practice) a. Using Figure 2.14 and assuming the variable name rate is assigned to the byte at memory address 159, determine the addresses corresponding to each variable declared in the following statements. Also, fill in the correct number of bytes with the initialization data included in the declaration statements. (Use letters for the characters, not the computer codes that would actually be stored.)
b. Repeat Exercise 9a, but substitute the actual byte patterns that a computer using the ASCII code would use to store characters in the variables ch1, ch2, ch3, and ch4. (Hint: Use Appendix B.)

Can you please help me determine it? Instructions: In the code editor, you are provided with an initial code which has main() function.In the main(), the user is asked for an integer input and then its address is assigned to a pointer variable (see line 9)Your task is to print the value of the pointer variable using the dereferencing operator.Input 1. An integer Output Enter n: 5Value of *ptr = 5arrow_forward(b) For the following C statement, write the corresponding LEGV8 assembly code.

For each of the following numbers,(a) determine whether the number is a 4-digit oating-point number (the number of the FPA4);(b) if yes, write the number in the standard form ±0.d1d2d3d4 × 10n, where d1 is a nonzero digit and n ∈ Z;(c) if no, rst chop and then round the number to a number of the FPA4, written in the standard form:(i) − 0.989067000000001; (ii) − 51.8; (iii) − 900.377050000001; (iv) − 5000.0;(v) − 0.023409; (vi) 2036.0; (vii) 0.01814.arrow_forward1. (Assembly Language Programming) Write a procedure gcd for finding the greatest common divisor (GCD) of two positive integers x and y, which is described in the C code below. int gcd (int x, int y) { if (y 0) == return x; else return gcd (y, x % y); } Assume that x and y are passed to procedure gcd via X4 and X5 and the result is returned in X2. Note that x % y is the remainder of x / y.arrow_forward[1] ( Show your work. Show hoe you compute memory address by using the effective memory address computation.

(3 Pts) In a certain computer architecture, the content of some registers and memory content currently is as follows. Memory Address Data R1 | 00000004 0000FFFE FO00128A R2 0000FFFE FO00128A 0000FFF0 Next, this computer execute the following instruction. ADDI (0000FFFE), R1 Note: The I in ADDI refers to Indirect. Indirect here deals with the destination address: (0000FFFE). The parentheses are standard for indirect addressing. ADDI means add content of source to content of destination and place result in destination. Given that it is immediately after the instruction above is executed, fill out the contents of registers and memory addresses below.

A user’s card must be registered with the user’s account number (10 digit), name, NRIC (12-digit) and three fingerprint samples of data type bitmap object. For a successful authentication, the correct bank-card provides the user’s account number to the ATM during read. The ATM retrieves fingerprint samples from a remote database. Then, the ATM requests the user to scan his right thumb finger print on an optical scanner. The algorithm authenticates the finger print against any of the three samples. A successful login requires a match of 99% on any one of the three samples. Question: Propose a class diagram. Draw a sequence diagram to illustrate the above sequence of process. Draw a wireframe design of the ATM User Interface (UI).arrow_forward
