A company database needs to store information about employees (identified by ssn, with salary and phone as attributes), departments (identified by dno, with dname and budget as attributes), and children of employees (with name and age as attributes). Employees work in departments; each department is managed by an employee; a child must be identified uniquely by name when the parent (who is an employee; assume that only one parent works for the company) is known. We are not interested in information about a child once the parent leaves the company.Draw an ER diagram that captures this information.
What is the output of the following code snippet if the variable named cost contains 100? if cost < 70 or cost > 150 : discount = 0.8 * cost else : discount = cost print("Your cost is ", discount)
Answer:
The output is: Your cost is 100
Explanation:
Given
The above code snippet
and
[tex]cost = 100[/tex]
Required
Determine the output of the code
if cost < 70 or cost > 150
The above condition checks if cost is less than 70 or cost is greater than 150
This condition is false because 100 is neither less than 70 nor is it greater than 150
So, the else statement will be executed.
discount = cost
Which means
discount = 100
So, the print instruction will print: Your cost is 100

g Write a program that reads a list of words, and a character. The output of the program is every word in the list of words that contains the character at least once. For coding simplicity, follow each output word by a comma, even the last one. Assume at least one word in the list will contain the given character. The number of input words is always less than and equal to 10. If the user enters more than 10 words before the character, the program will output Too many words and exit.
Answer:
Here you go, alter this as you see fit :)
Explanation:
array = []
cnt = 0
while cnt < 11:
x = input("Enter a word: ")
array.append(x)
cnt += 1
y = input("Add another word?(Y/n): ")
if y.lower() == "n":
break
letter = input("\nChoose a letter: ")
if len(letter) != 1:
print("Error: too many characters")
quit()
for n in range(len(array)):
if letter.lower() in array[n].lower():
print(array[n], end= ",")
String[][] arr = {{"Hello,", "Hi,", "Hey,"}, {"it's", "it is", "it really is"}, {"nice", "great", "a pleasure"},

{"you", "you again", "you all"}};
for (int j = 0; j < arr.length; j++) {
for (int k = 0; k < arr[0].length; k++) {
if (k == 1) { System.out.print(arr[j][k] + " ");
}
}
}
What, if anything, is printed when the code segment is executed?
Answer:
Explanation:
The code that will be printed would be the following...
Hi, it is great to get to see you again
This is mainly due to the argument (k==1), this argument is basically stating that it will run the code to print out the value of second element in each array within the arr array. Therefore, it printed out the second element within each sub array to get the above sentence.
When the code segment is executed, the output is "Hi, it is great to get to see you again "
In the code segment, we have the following loop statements
for (int j = 0; j < arr.length; j++) {for (int k = 0; k < arr[0].length; k++) {The first loop iterates through all elements in the array
The second loop also iterates through all the elements of the array.
However, the if statement ensures that only the elements in index 1 are printed, followed by a space
The elements at index 1 are:
"Hi," "it" "is" "great" "to" "get" "to" "see" "you" "again"
Hence, the output of the code segments is "Hi, it is great to get to see you again "

Declare an array of 10 integers. Initialize the array with the following values: 000 101 202 303 404 505 606 707 808 909 Write a loop to search the array for a given number and tell the user if it was found. Do NOT write the entire program. Example: User input is 404 output is "found". User input is 246 output is "not found"
Answer:
In C++:
#include <iostream>
using namespace std;
int main(){
int myArray[10] = {000, 101, 202, 303, 404, 505, 606, 707, 808, 909};
int num;
bool found = false;
cout<<"Search for: ";
cin>>num;
for(int i = 0;i<10;i++){
if(myArray[i]==num){
found = true;
break;
}
}
if(found){ cout<<"found"; }
else { cout<<"not found"; }
return 0;
}
Explanation:
This line initializes the array
int myArray[10] = {000, 101, 202, 303, 404, 505, 606, 707, 808, 909};
This line declares num as integer
int num;
This initializes boolean variable found to false
bool found = false;
This prompts user for input
cout<<"Search for: ";
This gets user input
cin>>num;
This iterates through the array
for(int i = 0;i<10;i++){
This checks if num is present in the array
if(myArray[i]==num){
If yes, found is updated to true
found = true;
And the loop is exited
break;
}
}
If found is true, print "found"
if(found){ cout<<"found"; }
If found is false, print "not found"
else { cout<<"not found"; }
Write the Number class that can be used to test if the number is odd, even, and perfect. A perfect number is any number that is equal to the sum of its divisors. Write the NumberAnalyzer class that has an ArrayList of Number to determine how many numbers in the list are odd, even, and perfect.
Answer:
Explanation:
The following code is written in Python. It creates a class that takes in one ArrayList parameter and loops through it and calls two functions that check if the numbers are Perfect, Odd, or Even. Then it goes counting each and printing the final results to the screen.
class NumberAnalyzer:
def __init__(self, myArray):
perfect = 0
odd = 0
even = 0
for element in myArray:
if self.isPerfect(element) == True:
perfect += 1
else:
if self.isEven(element) == True:
even += 1
else:
odd += 1
print("# of Perfect elements: " + str(perfect))
print("# of Even elements: " + str(even))
print("# of Odd elements: " + str(odd))
def isPerfect(self, number):

if number == sum:
return True
else:
return False
def isEven(self, number):

Segmentation Faults Recall what causes segmentation fault and bus errors from lecture. Common cause is an invalid pointer or address that is being dereferenced by the C program. Use the program average.c from the assignment page for this exercise. The program is intended to find the average of all the numbers inputted by the user. Currently, it has a bus error if the input exceeds one number. Load average.c into gdb with all the appropriate information and run it. Gdb will trap on the segmentation fault and give you back the prompt. First find where the program execution ended by using backtrace (bt as shortcut) which will print out a stack trace. Find the exact line that caused the segmentation fault.
Q13. What line caused the segmentation fault?
Q14. How do you fix the line so it works properly?
You can recompile the code and run the program again. The program now reads all the input values but the average calculated is still incorrect. Use gdb to fix the program by looking at the output of read_values. To do this, either set a breakpoint using the line number or set a breakpoint in the read_values function. Then continue executing to the end of the function and view the values being returned. (To run until the end of the current function, use the finish command).
Q15. What is the bug? How do you fix it?
//average.c
#include
/*
Read a set of values from the user.
Store the sum in the sum variable and return the number of values
read.
*/
int read_values(double sum) {
int values=0,input=0;
sum = 0;
printf("Enter input values (enter 0 to finish):\n");
scanf("%d",&input);
while(input != 0) {
values++;
sum += input;
scanf("%d",input);
}
return values;
}
int main() {
double sum=0;
int values;
values = read_values(sum);
printf("Average: %g\n",sum/values);
return 0;
}
Answer:
See Explanation
Explanation:
Q13. Line that caused the segmentation fault?
The segmentation fault was caused by line 15 i.e. scanf("%d",input);
Q14. How the line was fixed?
The reason for the segmentation fault is that the instruction to get input from the user into the integer variable "input" was not done correctly.
The correction to this is to modify scanf("d",input) to scanf("%d",input);
Q15. The bug?
The bug is that the method needs to return two value; the sum of the inputted numbers and the count of the inputted numbers.
However. it only returns the count of the inputted number.
So, the average is calculated as: 0/count, which will always be 0
How it was fixed?
First, change the method definition to: void and also include an array as one of its parameters.
void read_values(double sum, double arr []) {
Next:
assign sum to arr[0] and values to arr[1]
In the main method:
Declare an array variable: double arr [2];
Call the read_values function using: read_values(sum,arr);
Get the sum and values using:
sum = arr[0];
values = arr[1];
Lastly, calculate and print average:
printf("Average: %g\n",sum/values);

Which code segment results in "true" being returned if a number is even? Replace "MISSING CONDITION" with the correct code segment.
Answer Choices:
A. num % 2 == 0;
B. num % 0 == 2;
C. num % 1 == 0;
D. num % 1 == 2;
Answer:
num % 2 == 0
Explanation:
Functions are collection of code segments that are executed when called or evoked
The correct statement that can replace "MISSING CONDITION" is (a) num % 2 == 0
From the question, we understand that the condition is to return true if the number is an even number.
To do this, we simply take the modulus of the number and 2.
If the result of the modulus is 0, then the number is evenIf otherwise, then the number is oddHence, the correct statement that can replace "MISSING CONDITION" is (a) num % 2 == 0

Answer:
Written in Python:
def insert_string_multiple_times(str1,indto,str2,count):
splitstr = str1[:indto]
for i in range(count):
splitstr+=str2
splitstr +=str1[indto:]
print(splitstr)
Explanation:
This line defines the method
def insert_string_multiple_times(str1,indto,str2,count):
In the above definition:
str1 represents the string
indto represents index to insert a new string
str2 represents the new string to insert
count represents the number of times str2 is to be inserted
This gets the substring from the beginning to indto - 1
splitstr = str1[:indto]
This performs an iterative operation
for i in range(count):
This appends str2 to the first part of the separated string
splitstr+=str2
This appends the remaining part of the separated string
splitstr +=str1[indto:]
This prints the new string
print(splitstr)

It also has 3 functions, a constructor that takes the customer name as a parameter. The add_to_cart function which increases the amount of the current total. And finally the checkout function which applies the available coupon and resets the variables if needed, as well as prints the info the to screen.
class Customer():
customer = ""
purchased_history = 0
current_total = 0
def __init__(self, name):
self.customer = name

self.current_total += amount
def checkout(self):
if self.purchased_history >= 100:
self.current_total *= 0.90
self.purchased_history = 0
else:
self.purchased_history += self.current_total
print(self.customer + " current total is: $" + str(self.current_total))
self.current_total = 0
