What is a critical consideration on using cloud-based file sharing and storage applications.

Write a program that reads an integer, a list of words, and a character. The integer signifies how many words are in the list. T

hammer [34]

Answer:

In C++:

#include<iostream>

#include<vector>

using namespace std;

int main() {

int len;

cout<<"Length: "; cin>>len;

string inpt;

vector<string> vect;

for(int i =0;i<len;i++){

cin>>inpt;

vect.push_back(inpt); }

char ch;

cout<<"Input char: "; cin>>ch;

for(int i =0;i<len;i++){

size_t found = vect.at(i).find(ch);

if (found != string::npos){

cout<<vect.at(i)<<" ";

i++;

}

return 0;

}

Explanation:

This declares the length of vector as integer

int len;

This prompts the user for length

cout<<"Length: "; cin>>len;

This declares input as string

string inpt;

This declares string vector

vector<string> vect;

The following iteration gets input into the vector

for(int i =0;i<len;i++){

cin>>inpt;

vect.push_back(inpt); }

This declares ch as character

char ch;

This prompts the user for character

cout<<"Input char: "; cin>>ch;

The following iterates through the vector

for(int i =0;i<len;i++){

This checks if vector element contains the character

size_t found = vect.at(i).find(ch);

If found:

if (found != string::npos){

Print out the vector element

cout<<vect.at(i)<<" ";

And move to the next vector element

i++;

}

Write an if/else statement that compares the value of the variables soldYesterday and soldToday, and based upon that comparison

jenyasd209 [6]

Answer:

if(soldYesterday > soldToday){

salesTrend = -1;

} else if(soldToday > soldYesterday){

salesTrend = 1;

}

Explanation:

The if/else statement is more explicit. The first if condition check if soldYesterday is greater than soldToday, if true, then -1 is assigned to salesTrend.

Else if soldToday is greater than soldYesterday, if true, then 1 is assigned to salesTrend.

What will be displayed after code corresponding to the following pseudocode is run? Main Set OldPrice = 100 Set SalePrice = 70 C

Tatiana [17]

Answer:

A jacket that originally costs $ 100 is on sale today for $ 80

Explanation:

Main : From here the execution of the program begins

Set OldPrice = 100 -> This line assigns 100 to the OldPrice variable

Set SalePrice = 70 -> This line assigns 70to the SalePrice variable

Call BigSale(OldPrice, SalePrice) -> This line calls BigSale method by passing OldPrice and SalePrice to that method

Write "A jacket that originally costs $ ", OldPrice -> This line prints/displays the line: "A jacket that originally costs $ " with the resultant value in OldPrice variable that is 100

Write "is on sale today for $ ", SalePrice -> This line prints/displays the line: "is on sale today for $ " with the resultant value in SalePrice variable that is 80

End Program -> the main program ends

Subprogram BigSale(Cost, Sale As Ref) -> this is a definition of BigSale method which has two parameters i.e. Cost and Sale. Note that the Sale is declared as reference type

Set Sale = Cost * .80 -> This line multiplies the value of Cost with 0.80 and assigns the result to Sale variable

Set Cost = Cost + 20 -> This line adds 20 to the value of Cost and assigns the result to Cost variable

End Subprogram -> the method ends

This is the example of call by reference. So when the method BigSale is called in Main by reference by passing argument SalePrice to it, then this call copies the reference of SalePrice argument into formal parameter Sale. Inside BigSale method the reference &Sale is used to access actual argument i.e. SalePrice which is used in BigSale(OldPrice, SalePrice) call. So any changes made to value of Sale will affect the value of SalePrice

So when the method BigSale is called two arguments are passed to it OldPrice argument and SalePrice is passed by reference.

The value of OldPrice is 100 and SalePrice is 70

Now when method BigSale is called, the reference &Sale is used to access actual argument SalePrice = 70

In the body of this method there are two statements:

Sale = Cost * .80;

Cost = Cost + 20;

So when these statement execute:

Sale = 100 * 0.80 = 80

Cost = 100 + 20 = 120

Any changes made to value of Sale will affect the value of SalePrice as it is passed by reference. So when the Write "A jacket that originally costs $ " + OldPrice Write "is on sale today for $ " + SalePrice statement executes, the value of OldPrice remains 100 same as it does not affect this passed argument, but SalePrice was passed by reference so the changes made to &Sale by statement in method BigSale i.e. Sale = Cost * .80; has changed the value of SalePrice from 70 to 80 because Sale = 100 * 0.80 = 80. So the output produced is:

A jacket that originally costs $ 100 is on sale today for $ 80

17.8.1: Writing a recursive math function. Write code to complete raise_to_power(). Note: This example is for practicing recursi

Yuliya22 [10]

Answer:

The recursion function is as follows:

def raise_to_power(num, power):

if power == 0:

return 1

elif power == 1:

return num

else:

return (num*raise_to_power(num, power-1))

Explanation:

This defines the function

def raise_to_power(num, power):

If power is 0, this returns 1

if power == 0:

return 1

If power is 1, this returns num

elif power == 1:

return num

If otherwise, it calculates the power recursively

else:

return (num*raise_to_power(num, power-1))
