SimpleScalar is an architectural simulator which enables a study of how different pro-cessor and memory system parameters affect performance and energy efficiency.
a. True
b. False
Answer:
a. True
Explanation:
SimpleScalar refers to a computer architectural simulating software application or program which was designed and developed by Todd Austin at the University of Wisconsin, Madison, United States of America. It is an open source simulator written with "C" programming language and it's used typically for modelling virtual computer systems having a central processing unit (CPU), memory system parameters (hierarchy), and cache.
The main purpose of SimpleScalar is to avail developers or manufacturers the ability to compare two computers based on their capacities (specifications) without physically building the two computers i.e using a simulation to show or illustrate that computer B is better than computer A, without necessarily having to physically build either of the two computers.
Hence, it is an architectural simulator which makes it possible to study how different central processing units (CPUs), memory hierarchy or system parameters and cache affect the performance and energy efficiency of a computer system.

What is output? public class MathRecursive { public static void myMathFunction(int a, int r, int counter) { int val; val = a*r; System.out.print(val+" "); if (counter > 4) { System.out.print("End"); } else { myMathFunction(val, r, counter + 1); } } public static void main (String [] args) { int mainNum1 = 1; int mainNum2 = 2; int ctr = 0; myMathFunction(mainNum1, mainNum2, ctr); } }
a) 2 4 8 16 32 End
b) 2 2 2 2 2
c) 2 4 8 16 32 64 End
d) 2 4 8 16 32
Answer:
The output of the program is:
2 4 8 16 32 64 End
Explanation:
See attachment for proper presentation of the program
The program uses recursion to determine its operations and outputs.
The function is defined as: myMathFunction(int a, int r, int counter)
It initially gets the following as its input from the main method
a= 1; r = 2; counter = 0
Its operation goes thus:
val = a*r; 1 * 2 = 2
Print val; Prints 2
if (counter > 4) { System.out.print("End"); } : Not true
else { myMathFunction(val, r, counter + 1); }: True
The value of counter is incremented by 1 and the function gets the following values:
a= 2; r = 2; counter = 1
val = a*r; 2 * 2 = 4
Print val; Prints 4
else { myMathFunction(val, r, counter + 1); }: True
The value of counter is incremented by 1 and the function gets the following values:
a= 4; r = 2; counter = 2
val = a*r; 4 * 2 = 8
Print val; Prints 8
else { myMathFunction(val, r, counter + 1); }: True
The value of counter is incremented by 1 and the function gets the following values:
a= 8; r = 2; counter = 3
val = a*r; 8 * 2 = 16
Print val; Prints 16
else { myMathFunction(val, r, counter + 1); }: True
The value of counter is incremented by 1 and the function gets the following values:
a= 16; r = 2; counter = 4
val = a*r; 16 * 2 = 32
Print val; Prints 32
else { myMathFunction(val, r, counter + 1); }: True
The value of counter is incremented by 1 and the function gets the following values:
a= 32; r = 2; counter = 5
val = a*r; 32 * 2 = 64
Print val; Prints 64
if (counter > 4) { System.out.print("End"); } : True
This prints "End"
So; the output of the program is:
2 4 8 16 32 64 End

You will write code to manipulate strings using pointers but without using the string handling functions in string.h. Do not include string.h in your code. You will not get any points unless you use pointers throughout both parts.
You will read in two strings from a file cp4in_1.txt at a time (there will be 2n strings, and you will read them until EOF) and then do the following. You alternately take characters from the two strings and string them together and create a new string which you will store in a new string variable. You may assume that each string is no more than 20 characters long (not including the null terminator), but can be far less. You must use pointers. You may store each string in an array, but are not allowed to treat the string as a character array in the sense that you may not have statements like c[i] = a[i], but rather *c *a is allowed. You will not get any points unless you use pointers.

Create a public class called Exceptioner that provides one static method exceptionable. exceptionable accepts a single int as a parameter. You should assert that the int is between 0 and 3, inclusive.
If the int is 0, you should return an IllegalStateException. If it's 1, you should return a NullPointerException. If it's 2, you should return a ArithmeticException. And if it's 3, you should return a IllegalArgumentException.
// Begin class declaration
public class Exceptioner {
// Define the exceptionable method
public static void exceptionable(int number){
//check if number is 0.
if(number == 0) {
//if it is 0, return an IllegalStateException
throw new IllegalStateException("number is 0");
}
//check if number is 1
else if(number == 1) {
//if it is 1, return a NullPointerException
throw new NullPointerException("number is 1");
}
//check if number is 2
else if(number == 2) {
//if it is 2, return an ArithmeticException
throw new ArithmeticException("number is 2");
}
//check if number is 3

You plan to make a delicious meal and want to take the money you need to buy the ingredients. Fortunately you know in advance the price per pound of each ingredient as well as the exact amount you need. The program should read in the number of ingredients (up to a maximum of 10 ingredients), then for each ingredient the price per pound. Finally your program should read the weight necessary for the recipe (for each ingredient in the same order). Your program should calculate the total cost of these purchases, then display it with 6 decimal places.
Example There are 4 ingredients and they all have a different price per pound: 9.90, 5.50, 12.0, and 15.0. You must take 0.25 lbs of the first, 1.5 lbs of the second, 0.3 lbs of the third and 1 lb of the fourth. It will cost exactly $29.325000.
Answer:
In Python:
prices = []
pounds = []
print("Enter 0 to stop input")
for i in range(10):
pr = float(input("P rice: "+str(i+1)+": "))
pd = float(input("Pound: "+str(i+1)+": "))
if pr != 0 and pd != 0:
prices.append(pr)
pounds.append(pd)
else:
break
amount = 0
for i in range(len(pounds)):
amount+= (pounds[i]*prices[i])
print("Amount: $",amount)
Explanation:
These initialize the prices and pounds lists
prices = []
pounds = []
This prompts the user to enter up to 10 items of press 0 to quit
print("Enter 0 to stop input")
This iterates through all inputs
for i in range(10):
This gets the price of each item
pr = float(input("P rice: "+str(i+1)+": "))
This gets the pound of each item
pd = float(input("Pound: "+str(i+1)+": "))
If price and pound are not 0
if pr != 0 and pd != 0:
The inputs are appended to their respective lists
prices.append(pr)
pounds.append(pd)
If otherwise, the loop is exited
else:
break
This initializes total to 0
amount = 0
This iterates through all inputs
for i in range(len(pounds)):
This multiplies each pound and each price and sum them up
amount+= (pounds[i]*prices[i])
The total is then printed
print("Amount: $",amount)

If a system contains 1,000 disk drives, each of which has a 750,000- hour MTBF, which of the following best describes how often a drive failure will occur in that disk farm:
a. once per thousand years
b. once per century, once per decade
c. once per year, once per month
d. once per week
e. once per day
f. once per hour
g. once per minute
h. once per second
Answer:
once per month
Explanation:
The correct answer is - once per month
Reason -
Probability of 1 failure of 1000 hard disk = 750,000/1000 = 750 hrs
So,
750/24 = 31.25 days
⇒ approximately one in a month.

what is the role of computer in modern problem solving
Answer:
Una computadora es una herramienta muy básica para hacer tareas repetitivas de forma más eficiente. Una computadora no es capaz de analizar un problema y obtener una solución.
Explanation:
The function below takes one parameter: an integer (begin). Complete the function so that it prints every other number starting at begin down to and including 0, each on a separate line. There are two recommended approaches for this: (1) use a for loop over a range statement with a negative step value, or (2) use a while loop, printing and decrementing the value each time.
1 - def countdown_trigger (begin):
2 i = begin
3 while i < 0:
4 print(i)
5 i -= 1 Restore original file
Answer:
Follows are code to the given question:
def countdown_trigger(begin):#defining a method countdown_trigger that accepts a parameter
i = begin#defining variable that holds parameter value
while i >= 0:#defining while loop that check i value greater than equal to0
print(i)#print i value
i -= 2 # decreasing i value by 2
print(countdown_trigger(2))#calling method
Output:
2
0
None
Explanation:
In this code, a method "countdown_trigger" is declared, that accepts "begin" variable value in its parameters, and inside the method "i" declared, that holds parameters values.
By using a while loop, that checks "i" value which is greater than equal to 0, and prints "value" by decreasing a value by 2.

D. a blog.
Explanation:
Communication can be defined as a process which typically involves the transfer of information from one person (sender) to another (recipient), through the use of semiotics, symbols and signs that are mutually understood by both parties.
Generally, the linear model of communication comprises of four (4) main components and these are;
1. Sender (S): this is typically the source of information (message) or the originator of a message that is being sent to a receiver. Thus, they are simply the producer of a message.
2. Channel (C): this is the medium used by the sender for the dissemination or transmission of the message to the recipient. For example, telephone, television, radio, newspapers, billboards etc.
3. Message (M): this is the information or data that is being sent to a recipient by a sender. It could be in the form of a video, audio, text message etc.
4. Receiver (R): this is typically the destination of information (message) or the recipient of a message that is being sent from a sender.
Hence, the following are forms of media (communication channel);
I. A brochure distributed to many people. It comprises of printed textual informations used mainly for promotional purposes.
II. A blog. It is an online website that contains both textual and multimedia messages, especially as a news platform.

You are responsible for a rail convoy of goods consisting of several boxcars. You start the train and after a few minutes you realize that some boxcars are overloaded and weigh too heavily on the rails while others are dangerously light. So you decide to stop the train and spread the weight more evenly so that all the boxcars have exactly the same weight (without changing the total weight). For that you write a program which helps you in the distribution of the weight.
Your program should first read the number of cars to be weighed (integer) followed by the weights of the cars (doubles). Then your program should calculate and display how much weight to add or subtract from each car such that every car has the same weight. The total weight of all of the cars should not change. These additions and subtractions of weights should be displayed with one decimal place. You may assume that there are no more than 50 boxcars.
Example 1
In this example, there are 5 boxcars with different weights summing to 110.0. The ouput shows that we are modifying all the boxcars so that they each carry a weight of 22.0 (which makes a total of 110.0 for the entire train). So we remove 18.0 for the first boxcar, we add 10.0 for the second, we add 2.0 for the third, etc.
Input

Output

10.0

Answer:
The program in C++ is as follows:
#include <iostream>
#include <iomanip>
using namespace std;
int main(){
int cars;
cin>>cars;
double weights[cars];
double total = 0;
for(int i = 0; i<cars;i++){
cin>>weights[i];
total+=weights[i]; }
double avg = total/cars;
for(int i = 0; i<cars;i++){
cout<<fixed<<setprecision(1)<<avg-weights[i]<<endl; }
return 0;
}
Explanation:
This declares the number of cars as integers
int cars;
This gets input for the number of cars
cin>>cars;
This declares the weight of the cars as an array of double datatype
double weights[cars];
This initializes the total weights to 0
double total = 0;
This iterates through the number of cars
for(int i = 0; i<cars;i++){
This gets input for each weight
cin>>weights[i];
This adds up the total weight
total+=weights[i]; }
This calculates the average weights
double avg = total/cars;
This iterates through the number of cars
for(int i = 0; i<cars;i++){
This prints how much weight to be added or subtracted
cout<<fixed<<setprecision(1)<<avg-weights[i]<<endl; }
