What distinguishes a text file from a binary file? Can a text editor be used to see a binary or text file?

Mark the following statements as true or false. An output stream is a sequence of characters from a computer to an output device. (1) To use cin and cout in a program, the program must include the header file iostream. (1, 2) Suppose pay is a variable of type double. The statement cin pay, requires the input of a decimal number. (2) The statement cin length; and length cin; are equivalent. (2) When the statement cin numl num2; executes, then after inputting a number into the variable numl the program skips all trailing whitespace characters. (2) To use the predefined function sqrt in a program, the program must include the header file cmath. (3) The statement cin.get (ch); inputs the next nonwhitespace character into the variable ch. (4) When the input stream enters the fail state, the program terminates with an error message. (5) To use the manipulators fixed and showpoint, the program does not require the inclusion of the header file iomanip. (6) The statement cin right; sets the input of only the next variable right-justified. (7) To input data from a file, the program must include the header file fstream. (10)

(Practice) a. Write a set of two statements declaring the following objects as ifstream objects, and then opening them as text input files: inData.txt, prices.txt, coupons.dat, and exper.dat. b. Rewrite the two statements for Exercise 2a, using a single statement.
