Answer:
SELECT product_name, amount_due, amount_paid,
cancelled, amount_refunded
FROM products
ORDER BY product_name ASC;
Explanation:
SQL (Structured Query Language ) was used above.
The SELECT command is used to list all the variables we want in our output.
The FROM command signifies the location.
ORDER BY command ensures that your result is ordered
ASC means Ascending Order.
; signifies the end of the query.
NOTE: Underscores were used because variables cannot be written with spaces between them
Answer:
The answer to this question is given below in the explanation section
Explanation:
The correct answer to this question is: it used a more English-like syntax.
The software developer use high-level language to develop or author the program because it is more likely to English syntax and it would be easy for a software developer to author a program easily instead of using low level language and remembering ones and zeros.
Other options are not correct because:
It can be used on computers without microprocessors: Each computer has a microprocessor either you develop a program using high-level or low-level languages. Changes and modifications are easy in high-level language than in low-level languages. so, the option that prevents anyone from making changes to the software later is wrong. However, high-level languages are less complicated in learning and in authoring the programs but it does not use zeros and ones, it uses English-like syntax. So, the last option is also wrong.
Answer:
"Quotes"
Slashes \//
How '"confounding' "\" it is!
Explanation:
The question above is testing your knowledge of the "\" escape sequence, This escape sequence is used to introduce special formatting to the output of the System.out.print function in Java.
It can be used to introduce a new line \n
It can also be used to introduce a tab indentation \t
As in the question above it is used to introduce double quotes "" in this case \"
Also as we see the question above it can still be used to place backlashes to an output in this case we use two backlashes \\. The first is the escape sequence, the second \ gets printed out.
Answer:
Variable, operator, expression, value.
Explanation:
We could use variables, operators, expressions, and values in a mathematical formula, we're going to do an example with every part.
For this example we're going to use a simple sum formula:
First, we have 3 variables:
sum;
sum1;
sum2;
Second, we have 3 operators:
=, + and *
Third, we have our expression and 1 value:
sum = sum1 + (sum2 * 5);
(sum2 * 5) = expression;
5 = value;
We're going to see the result when we print the variable sum.
