Aleksandr [31]

Answer:

Explanation:

1. Write a program that declares an array named alpha with 50 components of the type double. Initialize the array so that the first 25 components are equal to the square of the counter (or index) variable and the last 25 components are equal to three times the index variable.

double alpha[50];

for (int i=0;i<25;i++)

{

alpha[i]=i*i;

alpha[i+25]=(i+25)*3;

}

2. Output the array so that exactly ten elements per line are printed.

for (int i=0;i<50;i++)

{

cout<<i+1<<". "<<alpha[i]<<" ";

if (((i+1)%10)==0)

{

cout<<endl;

}

}

3. Run your program again, but this time change the code so that the array is filled with random numbers between 1 and 100.

double alpha[50];

for (int i=0;i<50;i++)

{

alpha[i]=rand()%101;

}

for (int i=0;i<50;i++)

{

cout<<i+1<<". "<<alpha[i]<<" ";

if (((i+1)%10)==0)

{

cout<<endl;

}

}

4. Write the code that computes and prints the average of elements of the array.

double alpha[50],temp=0;

for (int i=0;i<50;i++)

{

alpha[i]=rand()%101;

temp+=alpha[i];

}

cout<<"Average :"<<(temp/50);

5. Write the code that that prints out how many of the elements are EXACTLY equal to 100.

double alpha[50],temp=0;

for (int i=0;i<50;i++)

{

alpha[i]=rand()%101;

if(alpha[i]==100)

{

temp++;

}

}

cout<<"Elements Exacctly 100 :"<<temp;

Please note: If you put each of above code to the place below comment it will run perfectly after compiling

#include <iostream>

using namespace std;

int main()

{

// If you put each of above code here it will run perfectly after compiling

return 0;

Write a SELECT statement that returns one row for each customer that has orders with these columns:

d1i1m1o1n [39]

Answer:

SELECT email_address,

SUM(item_price * Quantity) AS item_price_total,

SUM(discount_amount * Quantity) AS discount_amount_total

FROM Customers c

JOIN Orders o ON c.CustomerID = o.CustomerID

JOIN Order_Items oi ON o.OrderID = oi.OrderID

GROUP BY email_address

ORDER BY item_price_total DESC

Explanation:

In this SQL statement the SELECT statement selects the following columns:

email_address

item_price

Quantity

discount_amount

There are two tables Customers and Order_Items

SUM aggregate function is used to add the values of the product of the columns discount_amount and Quantity. It is also used to get the sum of the product of two columns discount_amount and Quantity.

A new temporary column named item_price_total is used to name the sum of the product of two columns discount_amount and Quantity using AS which is ALIAS and it is used to give a name to some columns or a table.

Similarly discount_amount_total name is given to the column which calculate the sum of the product of two columns i.e. discount_amount and Quantity.

JOIN is used here to join the columns from the tables Order_items and Customers.

GROUP BY is used to group the result of rows and is used with functions like SUM. Here the rows are grouped by the email address.

ORDER BY is used to order the result. Here the result is ordered by item_price_total in descending order.

This SELECT statement can also be written as following:

SELECT c.email_address,

SUM(o.item_price * o.Quantity),

SUM(o.discount_amount * o.quantity)

FROM customer c

JOIN Order_Items o ON o.id = c.id

GROUP BY c.email_address
