A 'array palindrome' is an array which, when its elements are reversed, remains the same (i.e., the elements of the array are sa

muminat

The code below is used to determine a recursive, bool-valued function, isPalindrome, that accepts an integer-valued array, and the number of elements and returns whether the array is a palindrome.

Explanation:

The code shows 'array palindrome' is an array which, when its elements are reversed, remains the same.

bool isPalindrome(arr[((n-1) - n) +1], n)

{

if (n == 0 || n == 1)

{

return true;

}

else if (arr[n-1] == isPalindrome(arr[], n-1)

{

return true;

}

else {

return false;

}

What does the following function return? void index_of_smallest(const double all, int startindex, int numberOfSlots); A. a doubl

Flauer [41]

Answer:

nothing

Explanation:

Because the return type of the function is void. void means does not return any thing.

The syntax of the function:

type name( argument_1, argument_2,......)

{

statement;

}

in the declaration the type define the return type of the function.

it can be int, float, double, char, void etc.

For example:

int count( int index);

the return type of above function is int. So, it return integer.

similarly,

void count(int index);

it return type is void. So, it does not return any thing.

Which of the following represents the bus topology? Multiple Choice All devices are connected to a central device, called a hub.

Yanka [14]

Answer: All devices are connected to a central cable or backbone.

Explanation:

"All devices are connected to a central cable or backbone". Bus Topology refers to a logical or physical network's design. Bus Topology is also the network setup for a LAN (Local Area Network) nodes connected to a "backbone" or cable. The Bus setup connects every single computer and network to a single cable. Among others, the type of cable implemented for bus topology is usually a coaxial cable.

Referential integrity constraints are concerned with checking INSERT and UPDATE operations that affect the parent child relation

Jet001 [13]

Answer:

a) true

Explanation:

In Computer programming, integrity constraints can be defined as a set of standard rules that ensures quality information and database are maintained.

Basically, there are four (4) types of integrity constraints and these are;

1. Key constraints.

2. Domain constraints.

3. Entity integrity constraints.

4. Referential integrity constraints.

Referential integrity is a property of data which states that each foreign key value must match a primary key value in another relation or the foreign key value must be null.

For instance, when a foreign key in Table A points to the primary key of Table B, according to the referential integrity constraints, all the value of the foreign key in Table A must be null or match the primary key in Table B.

Hence, the referential Integrity constraints ensures that the relationship between the data in a table is consistent and valid.

Hence, referential integrity constraints are concerned with checking INSERT and UPDATE operations that affect the parent child relationships.

<em>This ultimately implies that, referential Integrity are rules used in database management systems (DBMS) to ensure relationships between tables when records are changed is VALID (INSERT and UPDATE).</em>

<em>In a nutshell, it always ensures a primary key must have a matching foreign key or it becomes null. </em>
