"Simon Says" is a memory game where "Simon" outputs a sequence of 10 characters (R, G, B, Y) and the user must repeat the sequen

m_a_m_a [10]

Answer:

#include <iostream> // includes input output functions

#include <string> // used for string functions

using namespace std; // identifies objects like cout , cin

int main() { // body of the main function

int index; // index position of the elements

simonPattern = "RRGBRYYBGY"; //stores simon pattern

userPattern = "RRGBBRYBGY"; //stores user pattern

int userScore = 0; // used to store the user score

// loop compares characters of user and simon patterns

for ( index = 0; userPattern[index] == simonPattern[index]; ++index) {

userScore = userScore +1; // adds to the user score

if (userPattern[index] != simonPattern[index]){

//if user and simon pattern do not match

break; } } // breaks the loop

cout << "userScore is " << userScore; // prints the user score

Explanation:

The program compares the user pattern to simon pattern character by character and keeps adding one to the user score if the characters of both simon and user patterns match. The loop breaks if the character of user pattern does not match with that of simon matter. At the end the calculated user score is displayed in the output.

1. Student 1 to many Social security card

A student may have more than one

social security card (legally with the

same unique social security number),

and every social security number belongs

to a unique.

2. Student Many to Many Teacher

Generally students are taught by many

teachers and a teacher teaches many students.

3.ClassRoom Many to Many Wall

Do not forget that the wall is usually

shared by adjacent rooms.

4. Country 1 to 1 Current President

Assuming a normal country under normal

circumstances having one president at a

time.

5. Course Many to Many TextBook

A course may have many textbooks and

text book may be prescribed for different

courses.

6. Item Many to Many Order

Assuming the same item can appear

in different orders.

7. Student Many to Many Class

One student may take several classes.

Every class usually has several students.

8. Class Many to 1 Instructor

Assuming that every class has a unique

instructor. In case instructors were allowed

to team teach, this will be many-many.

9. Instructor 1 to 1 Office

Assuming every instructor has only one

office and it is not shared. In case of offices

shared by 2 instructors, the relationship

will be 2-1. Conversely, if any instructor has a joint

appointment and offices in both departments,

then the relationship will be 1-2. In a very general

case, it may be many-many.

10. E-bay Auction item 1-Many E-bay bid

1. Consider a client and a server connected through one router. Assume the router can start transmitting an incoming packet afte

mezya [45]

Answer:

As the total bytes are L, when h bytes out of L are sent from client to router the router immediately send these h bytes forward to next router. Thus simultaneously another set of h bytes reaches the router and therefore many actions are being performed in a simultaneous way.

Explanation:

For finding end to end delay, calculations are done and briefed.

All the paper work along with explanation is attached for better understanding.

A clock is reading 10:27:54.0 (hr:min:sec) when it is discovered to be 4 seconds fast. Explain why it is undesirable to set it b

lara31 [8.8K]

Answer:

(a)Applications Time Stamp Events

(b)S=0.5(W- $T_{skew}$ )+ $T_{skew}$ , where $T_{skew}$ ≤W≤ $T_{skew}$ +8.

Explanation:

Some applications assume that clocks always advance, so they could timestamp events under this assumption.

In our case we have the wrong timed clock, say W and the hardware clock H which is supposed to advance at a perfect rate.

We proceed to construct a software clock such that after 8 seconds we can replace the wrong timed clock with the software clock in good conditions.

Let us denote the software clock with S.

Then, S=c(W- $T_{skew}$ )+ $T_{skew}$ where:

$T_{skew}$ =The current Time(10:27:54) and;

c is to be found.

We already know that S= $T_{skew}$ +4 when W= $T_{skew}$ +8,

So:

S=c(W- $T_{skew}$ )+ $T_{skew}$

$T_{skew}$ +4=c( $T_{skew}$ +8- $T_{skew}$ )+ $T_{skew}$

4=8c

c=0.5

We obtain the formula

S=0.5(W- $T_{skew}$ )+ $T_{skew}$ , where $T_{skew}$ ≤W≤ $T_{skew}$ +8.
