Answer:
The debugged program is as follows:
A=2
B=2
For I=1 to 10
PRINT A
TEMP = A
A=B
B=TEMP+A
NEXT I
END
Explanation:
First, the value of B should be changed to 4 (because the second term of the sequence is 2
Next, change Display to Print because Q-basic uses the print keyword to display output
The sequence is not properly generated. So, I update that part of the program to:
<em>For I=1 to 10
</em>
<em>PRINT A
</em>
<em>TEMP = A
</em>
<em>A=B
</em>
<em>B=TEMP+A
</em>
<em>NEXT I
</em>
<em />
Lastly, the loop is controlled by variable I (not X).
So change NEXT X to NEXT I
Answer: Fourth- generation language
Explanation:Structured Query Language (SQL) is the language that is in the form of database structure which helps in the manipulation of the data and management as well.
SQL is considered as the fourth generation language because it is used for the accessing of the data from the database.It is also known for the advancement in the third generation language and thus also improving the language interface with users.
Answer: False
Explanation:
This means that the mappings between the two schemas may be specified in either one of these languages.In most relational DBMSs today, there is no specific language that performs the role of SDL. Instead, the internal schema is specified by a combination of functions, parameters, and specifications related to storage. These permit the DBA staff to control indexing choices and mapping of data to storage
