Web browsers communicate with web servers using the ___

Instructions

Thepotemich [5.8K]

The output file stream will be coded as such

ofstream output_file;

output_file.open("Ch4_Ex15_Output.txt", ios::out);

output_file << balance;

input.close();

output_file.close();

return 0;

}

<h3>Output file stream</h3>

Generally, Given the instructions we see that the program will "output account balance before and after withdrawal and service charges"

Therefore we must conclude at the output file stream bearing all information required.

double withdraw(double balance) {

cout << "Current Balance in the account: " << balance << endl;

if(balance <= 0) {

cout << "Insufficent balance" << endl;

return balance;

}

double withdraw;

cout << "Amount of money for withdraw: "; cin >> withdraw;

if(withdraw > 500) {

cout << "$500 per day can be withdrawn!";

return balance;

}

double charge = 0;

if(balance >= withdraw) {

balance -= withdraw;

charge = (withdraw <= 300) ? 0 : (withdraw - 300) * 0.04;

}

else {

char option;

cout << "Insufficient funds! Service charged $25, Want to withdraw money?(Y/N): ";

cin >> option;

if(option == 'Y' || option == 'y') {

balance -= withdraw;

charge = 25;

}

balance -= charge;

cout << "balance after Withdraw: " << balance << endl;

cout << "charge for transaction: " << charge << endl;

return balance;

}

int main() {

ifstream input;

input.open("Ch4_Ex15_Data.txt", ios::in);

double balance;

input >> balance;

balance = withdraw(balance);

ofstream output_file;

\therefore the output stream is

output_file.open("Ch4_Ex15_Output.txt", ios::out);

output_file << balance;

input.close();

output_file.close();

return 0;

}

Oxnard Casualty wants to ensure that their e-mail server has 99.98 percent reliability. They will use several independent server

sattari [20]

Answer:

The smallest number of servers required is 3 servers

<em />

Explanation:

Given

$Reliability = 99.98\%$

$Individual Servers = 95\%$

Required

Minimum number of servers needed

Let p represent the probability that a server is reliable and the probability that it wont be reliable be represented with q

Such that

$p = 95\%\\$

It should be noted that probabilities always add up to 1;

So,

$p + q = 1$ '

Subtract p from both sides

$p - p + q = 1 - p$

$q = 1 - p$

Substitute $p = 95\%\\$

$q = 1 - 95\%$

Convert % to fraction

$q = 1 - \frac{95}{100}$

Convert fraction to decimal

$q = 1 - 0.95$

$q = 0.05$

------------------------------------------------------------------------------------------------

<em>To get an expression for one server</em>

The probabilities of 1 servers having 99.98% reliability is as follows;

$p = 99.98\%$

Recall that probabilities always add up to 1;

So,

$p + q = 1$

Subtract q from both sides

$p + q - q = 1 - q$

$p = 1 - q$

So,

$p = 1 - q = 99.98\%$

$1 - q = 99.98\%$

Let the number of servers be represented with n

The above expression becomes

$1 - q^n = 99.98\%$

Convert percent to fraction

$1 - q^n = \frac{9998}{10000}$

Convert fraction to decimal

$1 - q^n = 0.9998$

Add $q^n$ to both sides

$1 - q^n + q^n= 0.9998 + q^n$

$1 = 0.9998 + q^n$

Subtract 0.9998 from both sides

$1 - 0.9998 = 0.9998 - 0.9998 + q^n$

$1 - 0.9998 = q^n$

$0.0002 = q^n$

Recall that $q = 0.05$

So, the expression becomes

$0.0002 = 0.05^n$

Take Log of both sides

$Log(0.0002) = Log(0.05^n)$

From laws of logarithm $Loga^b = bLoga$

So,

$Log(0.0002) = Log(0.05^n)$ becomes

$Log(0.0002) = nLog(0.05)$

Divide both sides by $Log0.05$

$\frac{Log(0.0002)}{Log(0.05)} = \frac{nLog(0.05)}{Log(0.05)}$

$\frac{Log(0.0002)}{Log(0.05)} = n$

$n = \frac{Log(0.0002)}{Log(0.05)}$

$n = \frac{-3.69897000434}{-1.30102999566}$

$n = 2.84310893421$

$n = 3 (Approximated)$

<em>Hence, the smallest number of servers required is 3 servers</em>
