Answer:
A) The type of data it will hold
Explanation:
In most programming languages, a variable must be decalared before it can be used. Variable declarations allows the compiller to make provision of memory space for the variable so the type of data must be defined accordingly with the name of the variable because different data types occuppy different spaces in memory for example
An integer is 32 bit integral value
A char is 16 bit unicode value
A double is 64 bit floating point value
Answer:
#include <iostream>
using namespace std;
void miles_to_km(float &miles)//function to convert miles to kilo meters.
{
miles=miles*1.6;
}
int main() {
float miles;
cout<<"Enter the miles"<<endl;
cin>>miles;//taking input of the miles..
miles_to_km(miles);//calling function that converts miles to km..
cout<<"The number of km is "<<miles<<endl;//printing the km.
return 0;
}
Output:-
Enter the miles
54
The number of km is 86.4
Explanation:
I have created a function miles_to_km of type void which has the argument miles passed by reference.In the function the variable miles is converted to kilo meters.Then in the main function the function is called with the value prompted from the user.Then printing the changed value.
Answer:
"Pattern Matching" is the correct choice.
Explanation:
- In computational science, pattern matching seems to be the testing and location of similar information occurrences or variations of any form between raw code or a series of tokens.
- Pattern matching in various computing techniques or interfaces is something of several fundamental as well as essential paradigms.
The other choices don't apply to the specified instance. So that the choice above seems to be the right one.
An end user has reported not receiving emails sent by a specific customer. The main reason for this is The email filter has quarantined the messages

Answer:
Option d is the correct answer for the above question.
Explanation:
- The above SQL statement firstly executes the from clause, because it searches the table from the database.
- Then it searches the duplicate vendor name with the help of having a clause. It is because having clause is used in the place where, when the statement has aggregation functions.
- Then select statement is executed which selects the vendor state by the count of the vendor state and displays it.
- So the duplicate vendor state number is presented on the screen. This output is stated from the option d. Hence option d is the correct answer while the other is not because the other option does not tell about the correct output, which is executed by the above query.
