A C++ program named examProg that has been coded to accept command-line arguments is run at the Unix command line as follows:

z1234567@turing:~$ ./examProg data.txt 20 3

What will be the value of the parameter argv[2]?

	A.	The integer value 20
	B.	The C string "20"
	C.	The C string "./examProg"
	D.	The C string "data.txt"

Assume that we have the following C++ program:

#include

using namespace std;

int num = 10;

int sum(int, int);

int main()

{

int x = 3, y = 5;

cout << sum(x, y) + num << endl;

return 0;

}

int sum(int a, int b)

{

return (a + b);

}

What is the storage class of the variable a?

	A.	automatic storage
	B.	static storage
	C.	dynamic storage
