Answer:
Following are the code to the given question:
#include <iostream>//header file
using namespace std;
int main()//main method
{
int r=26,x,y;//defining integer variable
char c;//defining a character variable
for(x= 1; y<= r; x++)//using for loop for count value
{
for(y= 1; y<= x; y++)//using for loop to convert value in triangle
{
c=(char)(y+64);//convert value into character
cout << c;//print character value
}
cout << "\n";//use print method for line break
}
return 0;
}
Output:
Please find the attachment file.
Explanation:
In this code, three integer variable "x,y, and r", and one character variable "c" is declared, that is used in the nested for loop, in the first for loop it counts the character value and in the next for loop, it converts the value into a triangle and uses the char variable to print its character value.
A way to store a sequence of letters, numbers or symbols.
This is the most accurate statement, though not entirely true.
Hope this helps.
Answer:
The corrected question is:
Write an SQL statement to display the WarehouseID, the sum of QuantityOnOrder and sum of QuantityOnHand, grouped by WarehouseID and QuantityOnOrder. Name the sum of QuantityOnOrder as TotalItemsOnOrder and the sum of QuantityOnHand as TotalItemsOnHand. Use only the INVENTORY table in your SQL statement.
Answer to this corrected question:
SELECT WarehouseID,
SUM(QuantityOnOrder) AS TotalItemsOnOrder,
SUM(QuantityOnHand) AS TotalItemsOnHand
FROM INVENTORY
GROUP BY WarehouseID, QuantityOnOrder;
According to the given question:
SELECT WarehouseID,
SUM(QuantityOnOrder) + SUM(QuantityOnHand) AS TotalItemsOnHand
FROM INVENTORY
GROUP BY WarehouseID, QuantityOnOrder;
Explanation:
- In the SQL statement SELECT statement is used to select the data from the table. Here the SELECT statement is used to select WarehouseID, Sum of the columns QuantityOnOrder and QuantityOnHand from INVENTORY table.
- The sum of QuantityOnOrder and QuantityOnHand columns are given the name of TotalItemsonHand (In case of the corrected question the sum of column QuantityOnOrder is named as TotalItemsOnOrder and the column QuantityOnHand is named as TotalItemsOnHand
) using Alias AS. Alias is the temporary name given to the columns or table to make them more readable.
- GROUP BY statement is used to arrange or "group" same data and is often use with aggregate functions like SUM function here. So the grouping here is done based on two columns WarehouseID and QuantityOnOrder.
- SUM function in this SQL statement is an aggregate function to calculate the sum of all value in the columns QuantityOnOrder and QuantityOnHand.
