Questions

1.  

   TRUE✓		FALSE✗		Object-oriented (OO) programmers often use the term object rather than things like "variable" or "memory location".
   TRUE✗		FALSE✓		OO programmers focus more on the actions their objects undergo than on the data making up the objects.
   TRUE✗		FALSE✓		The C++ object that represents the console screen or display is cin.
   TRUE✓		FALSE✗		To call a function with respect to an object, the object is placed on the left side of a period — the dot operator, in fact — and the function call on the right.

2. The term "calling object" refers to the object to the left of the dot operation used when calling a function with respect to an object. (The function call is actually quite normal and goes on the right of the afore-mentioned operation.)

3. Show how you would specify that one character should be thrown out of cin's buffer.

   
           cin.ignore();
   
   

   What if you wanted to throw up to 10 characters out but not past a colon (':') symbol?

   
           cin.ignore(10, ':');
   
   

   And what if you wanted to throw out as many characters as it takes to reach (and also throw out) a newline?

   
           cin.ignore(numeric_limits<streamsize>::max(), '\n');
