C program:

1, Make two parallel arrays, one to keep track of food names and another to keep track of the food prices. There will be a total of 10 items, with a total of about 100 characters for each food name title (i think we can use malloc for the strings and allocate it accordingly)

Basically it will be something like a menu:

1, we will enter the food information

2, it will list all the food names and prices

3,then it will show a total value of the food inventory

Thanks!

To clarify, this is basically an inventory tracking. The user is the one inputting the food names, like for example the user inputs Donut and the price for Donut $3.00 that would be tracked, then the user enters 9 more items+ their prices(this is where the parallel array comes in). giving us 10 food items in the inventory.

How do you simplify the following boolean expressions:

Y₃= X3' X2 X1 X0' + X3' X2 X1 X0 + X3 X2 X1 X0' +X3X2X1X0

Y2 = X3' X2 X1' X0' + X3' X2 X1' X0 + X3 X2 X1' X0' + X3 X2 X1' X0 +  X3 X2' X1' X0' + X3 X2' X1' X0 + X3 X2' X1 X0' + X3 X2' X1 X0

Y1 = X3' X2' X1 X0' + X3' X2' X1 X0 + X3' X2 X1 X0' + X3' X2 X1 X0 +  X3 X2' X1' X0' + X3 X2' X1' X0 + X3 X2 X1' X0' + X3 X2 X1' X0

Y0 = X3' X2' X1' X0 + X3' X2' X1 X0 + X3' X2 X1' X0 + X3' X2 X1 X0 +  X3 X2' X1' X0 + X3 X2' X1 X0 + X3 X2 X1' X0 + X3 X2 X1 X0

1. The Person class
a. Person is an abstract class.

b. All class variables of the Person class must be private.

c.is a class with a single constructor, Person(String lName, String fName, int birthYear, int birthMonth, int birthDay). All arguments of the constructor should be stored as class variables. There should only be getter methods for first and last name variables. There should be no getters or setters forbirthYear, birthMonth, birthDay.

4. The method computeAge() takes no arguments and returns the person’s computed age (as of today's date) as a string of the form "X years, Y months and Z days". Hint: Use the LocalDate and Period classes.

   i. e.g. "21 years, 2 months and 3 days". ii. e.g. "21 years and 3 days".

   iii. e.g. "21 years and 2 months". iv. e.g. "21 years".

   v. e.g. "2 months and 3 days".

5. The toString method returns a string comprised of the results of

   getFname, getLName and computeAge. E.g.
   i. “Bunny Bugs is 19 years and 1 day old”

Configure and code clock for Pic24e referring to the example C code given below.

a) Write code on how to configure bits that uses its fast RC oscillator with PLL to run at 40MHz. Assume the RC's frequency is 7.5MHz.

b) Write code on how to configure bits that uses its primary crystal (XT) with PLL to run at 40MHz. Assume the external clock is a crystal oscillator of 8MHz.

====== Given C Code =======

#include "ConfigurationBits.h"

void initializeSystem() {

// Configure the device PLL to obtain 60 MIPS operation. The crystal

// frequency is 8MHz. Divide 8MHz by 2, multiply by 60 and divide by

// 2. This results in Fosc of 120MHz. The CPU clock frequency is

// Fcy = Fosc/2 = 60MHz.

PLLFBD = 58; /* M = 60 */

4. What is ZooKeeper? Who developed it? Describe its main functions.

Write a C program in Unix which uses a function called search to find

the location of a value in THREE arrays of floats. The function should

take three parameters :

         the value to be found

         the array to be searched

         the size of the array

N.B.!!!! The main program should read in three arrays of varying size

         example : array a has twelve elements

                   array b has six elements

                   array c has nine elements

                   array d has four elements

         input to these arrays terminated by illegal input(see handout)

         the function should return for each array the index where the

         value is found. If not found the function should return -1.

Stack - Implementation.

You will be able to use the push, pop and peek of Stack concept. Post-Fix calculator - When an arithmetic expression is presented in the postfix form, you can use a stack to evaluate the expression to get the final value. For example: the expression 3 + 5 * 9 (which is in the usual infix form) can be written as 3 5 9 * + in the postfix. More interestingly, post form removes all parentheses and thus all implicit precedence rules.

Program Implementation Requirements

Use the stack concept to create a post-fix calculator. I will be using a test-harnessPreview the document to run your program. Please make sure it meets the requirements to be run by the test harness.

Test harness:

public class StackCalcTest {

public static void main(String[] args) {

StackCalc stackCalc = new StackCalc();

String[] values = {"3", "5", "9", "*", "+"};

for(int i = 0; i < 5; i++) {

stackCalc.stack.push(values[i]);

}

System.out.println(stackCalc.stack);

System.out.println(stackCalc.answer()); }}

Sample run 1:

You entered:    95, 80, 100, 70

Highest grade: 100

Lowest grade:   70
