### Computer Science Quiz#### Question 1: Hexadecimal Representation**Question:** How many hexadecimal digits are used when representing a nibble in hex form?**Options:**- 1- 3- 2- 0#### Question 2: Function Parameters and Stack Alignment**Scenario:** Patti the Programmer decides to create a function with three int16 parameters, sending all three by-reference. Will she need to pad her function’s activation record to make it 32-bit aligned?**Options:**- The answer will depend on how many registers get preserved on the stack.- Yes- No- The answer will depend on the value of the passed parameters.#### Question 3: Memory Usage for Function Parameters**Question:** How many bits of stack memory are used when passing an int16 variable by-value to a function?**Options:**- 32- 64- 16- 8### Explanation of Concepts1. **Hexadecimal Digits and Nibbles:** - A **nibble** equals 4 bits. - Each hexadecimal digit represents exactly 4 bits.2. **Stack Alignment:** - Aligning data in memory can be necessary to meet the processor's requirements and improve performance. - A 32-bit alignment means data is aligned at addresses divisible by 4 bytes.3. **Stack Memory for int16:** - An **int16** is a 16-bit integer, meaning it occupies 16 bits in memory when passed by value.

The above question is solved in step 2 :-

Instructions: You are strictly not allowed to use anything other than pointers and dynamic memory. One function should perform one functionality only. Task 1 Write a program in C++ that reads data from a file. Create dynamic memory according to the data. Now your task is to perform the following task. Row wise Sum Column wise Sum Diagonal wise Sum Example data.txt 4 5 1.6 10.2 33.7 99 20.5 3 44 50 96.1 2 8 9 4 74 50 99 19.1 Output: Sum row wise: 165, 191, 17, 242.1 Sum col wise: 127.6, 120.1, 228.8, 118.1, 20.5 Sum diagonal wise: Not Possible Note: You are restricted to use pointers and your function should be generic. Avoid memory wastage, memory leakage, dangling pointer. Use regrow or shrink concepts if required.
I have seen some programs for these has been assignment but can this Assignment be programmed any other way? Thank you Memory Management Programming Assignment implement and test the GET-MEMORY algorithm This algorithm uses the Next-Fit(First-Fit-With-A-Roving-Pointer) technique. implement and test the FREE-MOMORY algorithm Implement the “GET_MEMORY” and “FREE_MEMORY” algorithms. Comprehensive testing must be done for each algorithm. Following are sample run results for each: GET_MEMORY IS RUNNING……… Initial FSB list FSB# Location Size 1 7 4 2 14 10 3 30 20 . . . . . .

The program below uses pointer arithmetic to determine the size of a 'char'variable. By using pointer arithmetic we can find out the value of 'cp' and thevalue of 'cp+1'. Since cp is a pointer, this addition involves pointer arithmetic:adding one to a pointer makes the pointer point to the next element of the sametype.For a pointer to a char, adding 1 really just means adding 1 to the address, butthis is only because each char is 1 byte.1. Compile and run the program and see what it does.2. Write some code that does pointer arithmetic with a pointer to an int anddetermine how big an int is.3. Same idea – figure out how big a double is, by using pointer arithmetic andprinting out the value of the pointer before and after adding 1.4. What should happen if you added 2 to the pointers from exercises 1through 3, instead of 1? Use your program to verify your answer.#include <stdio.h>int main( ){ char c = 'Z'; char *cp = &c; printf("cp is %p\n", cp); printf("The character at cp is…

PART 1: ONE-DIMENSIONAL ARRAY Instruction: There are two lists of numbers. Create a resultant list whose elements are the product of the elements of the two lists. Example: List A 21 List B List C 630 500 30 50 10 Write a Java program using a one-dimensional array that accepts as input an integer value asking for the number of elements for each list. This will be used to generate random numbers (5 to 69) for the one-dimensional arrays (List A and List B). The program will compute for the product and store it in another array (List C). Display the result similar to the Example above. Sample Input/Output: Depicted below are sample outputs when the program is executed (the items in bold characters are input from the user, while the items in bold italic are generated, calculated and printed by the program): Input the number of elements: 3 List A List B List C 630 500 250 21 30 50 10 25 10 Input the number of elements: 5 List A List B List C 31 13 403 21 30 630 500 50 10 60 41 2460 25 10…
In a letter to the editor of CACM, Rubin (1987) uses the following code segment as evidence that the readability of some code with gotos is better than the equivalent code without gotos. This code finds the first row of an n by n integer matrix named x that has nothing but zero values. for $ (i=1 ; i<=n ; i++)\{ $ for $ (j=1 ; j<=n ; j++) $ if $ (x[i][j] !=0) $ goto reject; println (First all-zero row Show Transcribed Text Rewrite this code without gotos either in C or Java. Compare the readability of your code to that of the example code. No hand written solution and no image

IN SCALA PLEASE COULD YOU COMPLETE THE FUNCTIONS: is_pow_of_two, is_hard, last_odd //(1) Complete the collatz function below. It should // recursively calculate the number of steps needed // until the collatz series reaches the number 1. // If needed, you can use an auxiliary function that // performs the recursion. The function should expect // arguments in the range of 1 to 1 Million. def collatz(n: Long) : Long = { if(n == 1) 0else if(n % 2 == 0) 1 + collatz(n/2) else1 + collatz(n*3 + 1) } //(2) Complete the collatz_max function below. It should // calculate how many steps are needed for each number // from 1 up to a bound and then calculate the maximum number of // steps and the corresponding number that needs that many // steps. Again, you should expect bounds in the range of 1 // up to 1 Million.
