Standard Integer Input (Exercise 2 Chapter 4)

Standard input is extracted cin, the standard input stream using the extraction operator (>>).
When inputting a number, the extraction operator will "search" for the number by skipping over any leading whitespace (blanks and end of lines).
Input stops when an inappropriate character for that number type is found.
Thus >> reads only as many characters from cin as are needed to form a number.
Any characters after the number (including the character that stopped the input) are still available for the next input operation.

(see pages 133-138 in the textbook).

Given two lines of input (that you may type in on the keyboard):

17 13
7 3 24 6

and the following input statements (where all the variables are of type int)

	cin >> int1 >> int2 >> int3;
	cin >> int4;

What is the value of the following?

  1. int1

  2. int2

  3. int3

  4. int4
