A function prototype can always be omitted when: A function is defined before it is first invoked. A function does not return a

krok68 [10]

Answer:

A function is defined before it is first invoked.

Explanation:

A function prototype is a term in computer programming that is used as the declaration of a function that specifies function's name, parameters and return type. However, unlike function itself, which specifies what it does, a function prototype specifies function's interface only and not what it does.

Hence, A function prototype can always be omitted when: a function is defined before it is first invoked.

Answer:

Check the explanation

Explanation:

CODE:

static int findEvenQueue(Queue<Integer> numbers)

{

//loop runs till the queue has atleast one element

while(numbers.size() > 0)

{

//Checking the head of the queue whether it is even

int temp = numbers.peek();

if(temp % 2 == 0)

{

//if the head is even then return it

return temp;

}

else

{

//else remove the number at head

int removed = numbers.poll();

}

//if no even number present in the Queue then return -1

return -1;

The DDBMS Scenario

OlgaM077 [116]

Answer and Explanation:

At C:

a.) This SQL sequence represents a remote request.

b.) This SQL sequence represents a remote request.

c.)This SQL sequence represents a distributed request. Note that the distributed request is required when a single request must access two DP sites. The PRODUCT table is composed of two fragments, PRO_A and PROD_B, which are located in sites A and B, respectively.

d.)This SQL sequence represents a distributed request.

Note that UPDATE CUSTOMER and the two INSERT statements only require remote request capabilities. However, the entire transaction must access more than one remote DP site, so we also need distributed transaction capability. The last UPDATE PRODUCT statement accesses two remote sites because the PRODUCT table is divided into two fragments located at two remote DP sites. Therefore, the transaction as a whole requires distributed request capability.

e.)This SQL sequence represents a distributed transaction. Note that, in this transaction, each individual request requires only remote request capabilities. However, the transaction as a whole accesses two remote sites. Therefore, distributed request capability is required.

At A:

f.)This SQL sequence represents a distributed request. Note that the request accesses two DP sites, one local and one remote. Therefore distributed capability is needed.

g.)This SQL sequence represents a remote request, because it accesses only one remote DP site.

h.)This SQL sequence represents a distributed request. In this case, the PRODUCT table is partitioned between two DP sites, A and B. Although the request accesses only one remote DP site, it accesses a table that is partitioned into two fragments: PROD-A and PROD-B. A single request can access a partitioned table only if the DBMS supports distributed requests.

At B:

i.)This SQL sequence represents a remote request.

j.)This SQL sequence represents a distributed request.

k.)This SQL sequence represents a distributed request. (See explanation for part h.)
