An active card is used in relation to computers and technology, it has the component of an internal battery and wouldn't be used without it. The active card can provide a usable range of up to 150 m distance. And this is the distance of how far that it could get.
I think that is the stupidest question ever (No offence). Of course you would use the one that doesn't need clearance or fee's. Like, Duh!
But I guess you also have to consider the quality of your pictures. If this physics lab write-up may be considered for some national competition (reusing the same paper for a different scenario) then I'd think that it's really up to you. Which one do you like the most?
To wrap things up, I honestly would choose the free one, but it always depends on your situation. How important is this project? Is this just homework for the teacher or is it going to be something bigger?
Answer:
a
Explanation:
The switch statement in the question above is written in C++ programming language. Firstly a variable of type char is declared and assigned a value of a. The switch statement then checks this value and executes the statement that follows, observe that in all cases, it checkes both the upper and lower case letters, also the value that is printed is the value stored in the variable ch and not the string ch. The code has also been to print the same output when any of the values a,b,c or d are entered.

The C++ code is given below with appropriate comments for better understanding
Explanation:
/*C++ program that prompts user to enter the name of input file(input.txt in this example) and print the sum of the values in the file to console. If file dosnot exist, then close the program */
//header files
#include <fstream>
#include<string>
#include <iostream>
#include <cstdlib> //needed for exit function
using namespace std;
//function prototype
int fileSum(string filename);
int main()
{
string filename;
cout << "Enter the name of the input file: ";
cin >> filename;
cout << "Sum: " << fileSum(filename) << endl;
system("pause");
return 0;
}
/*The function fileSum that takes the string filename and
count the sum of the values and returns the sum of the values*/
int fileSum(string filename)
{
//Create a ifstream object
ifstream fin;
//Open a file
fin.open(filename);
//Initialize sum to zero
int sum=0;
//Check if file exist
if(!fin)
{
cout<<"File does not exist ."<<endl;
system("pause");
exit(1);
}
else
{
int value;
//read file until end of file exist
while(fin>>value)
{
sum+=value;
}
}
return sum;
}//end of the fileSum
Answer:
To create a list of the cells A2 to A12, convert the A2: A12 range to a table, then select the data validation tab, input list as the type and the name of the A2:A12 range table, and then click ok. This list can now be used as a validation list in another column or worksheet.
Explanation:
Microsoft Excel provides the power of tables and list for categorized data and data validation.
