Answer:
You use an append query when you need to add new records to an existing table by using data from other sources. If you need to change data in an existing set of records, such as updating the value of a field, you can use an update query.
Answer:
Explanation:
The following code is written in Java. Both functions traverse the linkedlist, until it reaches the desired index and either returns that value or deletes it. If no value is found the function terminates.
public int GetNth(int index)
{
Node current = head;
int count = 0;
while (current != null)
{
if (count == index)
return current.data;
count++;
current = current.next;
}
assert (false);
return 0;
}
public int removeNth(int index)
{
Node current = head;
int count = 0;
while (current != null)
{
if (count == index)
return current.remove;
count++;
current = current.next;
}
assert (false);
return 0;
}
Answer:
See attachment for flowchart
Explanation:
The flowchart is represented by the following algorithm:
1. Start
2. Input Mass
3. Input Volume
4 Density = Mass/Volume
5. Print Density
6. Stop
The flowchart is explained by the algorithm above.
It starts by accepting input for Mass
Then it accepts input for Volume
Step 4 of the flowchart/algorithm calculated the Density using the following formula: Density = Mass/Volume
Step 5 prints the calculated Density
The flowchart stops execution afterwards
Note that the flowchart assumes that the user input is of number type (integer, float, double, etc.)
