Write an SQL query to select productID, productName, and unitCost from the Products table where unitCost is 100. Also, write a Pascal program to calculate the product based on given conditions.

The query needs to display productID, productName, and unitCost. We will assume these columns are in a table named Products.

The condition "display AT '100' in the unitCost" implies that the unitCost should be exactly 100.

The SQL query is:

SELECT productID, productName, unitCost
FROM Products
WHERE unitCost = 100;

SELECT productID, productName, unitCost FROM Products WHERE unitCost = 100;

TASK 2 (Programming):

The algorithm specifies i, n, product, Snum as integers. The loop also uses a counter variable, which should also be an integer.

The algorithm states to read three integers into i, n, Snum. Then, product is initialized to i, and counter to 1.

The loop continues as long as counter is less than or equal to n. Inside the loop, product is updated by multiplying it with Snum, and counter is incremented.

After the loop finishes, the final calculated product is printed.

Program Practici;
Var
  i, n, product, Snum, counter: integer;
Begin
  readln(i, n, Snum);
  product := i;
  counter := 1;
  while counter <= n do
  begin
    product := product * Snum;
    counter := counter + 1;
  end;
  writeln(product);
End.

\begin{align*}
&Program Practici;\ &Var\ &\quad i, n, product, Snum, counter: integer;\ &Begin\ &\quad readln(i, n, Snum);\ &\quad product := i;\ &\quad counter := 1;\ &\quad while counter <= n do\ &\quad begin\ &\quad \quad product := product * Snum;\ &\quad \quad counter := counter + 1;\ &\quad end;\ &\quad writeln(product);\ &End.
