The computer scientists Richard Conway and David Gries once wrote: The absence of error messages during translation of a computer program is only a necessary and not a sufficient condition for reasonable [program] correctness. Rewrite this statement without using the words necessary or sufficient.
Answers
Answer:
A computer program is not reasonably correct if it has no error messages during translation.
Explanation:
First, we need to understand what the statement means, and we also need to identify the keywords.
The statement means that, when a program does not show up error during translation; this does not mean that the program is correct
Having said that:

Assume in the for loop header, the range function has the three arguments: range (1, 10, 3), if you were to print out the value of the variable
in the for loop header, what will be printed out? List the values and separate them with a comma.
Answers
Answer:
1, 4, 7
Explanation:
The instruction in the question can be represented as:
for i in range(1,10,3):
print i
What the above code does is that:
It starts printing the value of i from 1
Increment by 3
Then stop printing at 9 (i.e.. 10 - 1)
So: The sequence is as follows
Print 1
Add 3, to give 4
Print 4
Add 3, to give 7
Print 7
Add 3, to give 10 (10 > 10 - 1).
So, it stops execution.

1. Add the following method to the Point class:
public double distance(Point other)
Returns the distance between the current Point object and the given other Point object. The distance between two points is equal to the square root of the sum of the squares of the differences of their x- and y-coordinates. In other words, the distance between two points (x1, y1) and (x2, y2) can be expressed as the square root of (x2 - x1)2 + (y2 - y1)2. Two points with the same (x, y) coordinates should return a distance of 0.0.
public class Point {
int x;
int y;
// your code goes here
}
2. Create a class called Name that represents a person's name. The class should have fields named firstName representing the person's first name, lastName representing their last name, and middleInitial representing their middle initial (a single character). Your class should contain only fields for now.
3. Add two new methods to the Name class:
public String getNormalOrder()
Returns the person's name in normal order, with the first name followed by the middle initial and last name. For example, if the first name is "John", the middle initial is 'Q', and the last name is "Public", this method returns "John Q. Public".
public String getReverseOrder()
Returns the person's name in reverse order, with the last name preceding the first name and middle initial. For example, if the first name is "John", the middle initial is 'Q', and the last name is "Public", this method returns "Public, John Q.".
4. Add the following method to the Point class:
public int quadrant()
Returns which quadrant of the x/y plane this Point object falls in. Quadrant 1 contains all points whose x and y values are both positive. Quadrant 2 contains all points with negative x but positive y. Quadrant 3 contains all points with negative x and y values. Quadrant 4 contains all points with positive x but negative y. If the point lies directly on the x and/or y axis, return 0.
public class Point {
private int x;
private int y;
// your code goes here
}

What you need to know In this program, a roll string is a number, followed by a lowercase "d", followed by another number. The first number is the number of dice to roll. The second number is the number of sides on each die. For example, 1d6 means there is one die with six sides. The total output of the roll is a random whole number between one and six, inclusive. 2d8 means there are two dice, each with eight sides. The total output of the roll is a random whole number between two and 16, inclusive. Since we are using a computer, we can have an input like 500d1000 (meaning a 1000-sided die, rolled 500 times) which would not be possible in real life.
Function: get_roll(rollstring)
This function takes an input parameter as a string that looks like "1d3", "3d5", etc. The function should return an integer simulating those dice rolls. In the case of "3d5", for example, the function will generate a random number between one and five, three times, and return the total (sum) as an integer. This function should return the value back to get_damage().
Function: get_damage(attack, defense)
This function gets the value of damage based on roll strings. Player 1 (the first roll) is always on attack; Player 2 (the second roll) is always on defense. If the defense roll is greater than the attack roll, return 0. Otherwise, return attack minus defense, as an integer. This function should call get_roll() twice, once for each Player. This function should return the value back to main_main().
Function: main_menu()
In this function, ask the user how many rounds they want to play. Next, ask the user to input Player 1 and Player 2’s dice for roll one, roll two, etc., up to the number of rolls they entered. The rolls for each round must be entered on one line with no spaces. This function should call get_damage() for each round.
Answers
Answer:
import random
def get_damage(attack,defense):
attack_roll = get_roll(attack)
defense_roll = get_roll(defense)
if defense_roll>attack_roll:
return 0
else:
return attack_roll-defense_roll
def main_menu():
rounds = int(input('Enter the number of rounds to play? '))
for round in range(1,rounds+1):
p1= input('Player 1 enter rollstring: ')
p2= input('Player 1 enter rollstring: ')
damage = get_damage(p1,p2)
print('Round: #{}, Damage: {}'.format(round,damage))
def get_roll(rollstring):
dices, sides = rollstring.split('d')
total = 0
for roll in range(int(dices)):
total += random.randint(1, int(sides))
return total
main_menu()
Explanation:
The main_menu python function is the module dice game that prompts for user input to get the number of times a round is played to call the get_damage function which in turn calls the get_roll function to simulate the dice roll and return the accumulated total of the sum of the random dice value.

80. A .......... is used to read or write data.
A. CD B. VDU C. ROM D. RAM
Answers
Answer:
Depending on exactly what they mean by read and write, both A and D are valid. In fact, if you read that as "read or write" as being a logical OR and not the logical AND that the sentence probably intends, then all four answers could be correct.
What they probably mean to say though is "..... is used as a read/write storage medium", in which case A is the correct answer.
A. Data can be written to or read from a CD. This is probably the "right" answer
B. A human can "read" data from a Visual Display Unit, and the computer "write" it. That of course is not the intended meaning though.
C. Data can be read from Read Only Memory, but not written to.
D. Data can be both read and written to Random Access Memory, but not retained after the computer is powered off.

how to learn python ?
Answers
Answer:
See below.
Explanation:
To learn python programming language, first, you have to know the basic. Surely, you may recognize this function namely print()
print(“Hello, World!”) — output as Hello, World!
First, start with familiarizing yourself with basic function such as print. Then step up with arithmetic and declare or assign variable then list.
Here are example of functions:
1.) print(argument) — If argument is a string (word-typed), make sure to use “” or ‘’ or else it’ll output an error and say the argument is not defined.
print(“Hi, Brainly”) will output Hi, Brainly
print(2+3) will output 5
Numerical data or numbers do not necessarily require “ “ or ‘ ‘
print(3+3) will output 6 but print(“3+3”) will output 3+3 which is now a string.
2.) type(argument) - this tells you which data/argument it is. There are
< class ‘str’ > which is string, meaning it contains “ “ or ‘ ‘< class ‘int’ > which is integer< class ‘float’ > which is decimal (20.0 is also considered as float, basically anything that contains decimal is all float type)< class ‘list’ > which is a list. List is something that contains elements within square brackets [ ]etc.
Make sure you also do print(type(argument)) as well so it will print out the output.
3.) Arithmetic
+ is additionEx. print(1+3) will output 4
2. - is subtraction
Ex. print(5-4) will output 1
3. * is multiply
Ex. print(4*5) will output 20
4. ** is exponent
Ex. print(5**2) will output 25
5. / is division
Ex. print(6/3) will output 2 — sometimes will output the float type 2.0
6. % is modulo or remainder
Ex. print(7%2) will output 1
4.) Variables
To assign a variable, use =
An example is:
x = 2
y = 5
print(x+y) will output 7
print(type(x)) will output the < class ‘int’ >
These are examples of what you’ll learn in basic of python - remember, programming depends on experience and always focus on it. Keep practicing and searching will improve your skill at python.
Consider two different implementations, M1 and M2, of the same instruction set. There are three classes of instructions (A, B, and C) in the instruction set. M1 has a clock rate of 60MHz and M2 has a clock rate of 80MHz. The average number of cycles of each instruction class and their frequencies (for a typical program) are as follows:
Instruction Class M1-cycles M2-cycles/ Frequency
/instruction class instruction class
A 1 2 50%
B 2 3 20%
C 3 4 30%
a. Calculate the average CPI for each machine, M1 and M2.
b. Calculate the CPU execution time of M1 and M2.
Answers
Explanation:
A.)
we have two machines M1 and M2
cpi stands for clocks per instruction.
to get cpi for machine 1:
= we multiply frequencies with their corresponding M1 cycles and add everything up
50/100 x 1 = 0.5
20/100 x 2 = 0.4
30/100 x 3 = 0.9
CPI for M1 = 0.5 + 0.4 + 0.9 = 1.8
We find CPI for machine 2
we use the same formula we used for 1 above
50/100 x 2 = 1
20/100 x 3 = 0.6
30/100 x 4 = 1.2
CPI for m2 = 1 + 0.6 + 1.2 = 2.8
B.)
CPU execution time for m1 and m2
this is calculated by using the formula;
I * CPI/clock cycle time
execution time for A:
= I * 1.8/60X10⁶
= I x 30 nsec
execution time b:
I x 2.8/80x10⁶
= I x 35 nsec

The child’s game, War, consists of two players each having a deck of cards. For each play, each person turns over the top card in his or her deck. The higher card wins that round of play and the winner takes both cards. The game continues until one person has all the cards and the other has none. Create a program that simulates a modified game of War.
The computer will play both hands, as PlayerOne and PlayerTwo, and, for each round will generate two random numbers and compare them.
If the first number is higher, PlayerOne’s score is increased by 1 and if the second number is higher, PlayerTwo’s score is increased by 1.
If there is a tie, no score is incremented.
When one "player" reaches a score of 10, that player should be deemed the winner and the game ends.
The range of numbers should be 1-13 to simulate the values of cards in the deck.

For this exercise, you are going to complete the printScope() method in the Scope class. Then you will create a Scope object in the ScopeTester and call the printScope.
The method will print the name of each variable in the Scope class, as well as its corresponding value. There are 5 total variables in the Scope class, some of which can be accessed directly as instance variable, others of which need to be accessed via their getter methods.
For any variable that can be accessed directly, use the variable name. Otherwise, use the getter method.
Sample Output:
The output of the printScope method should look like this:
a = 5
b = 10
c = 15
d = 20
e = 25
