The cin statement will stop reading input when it encounters a new line character
True
You can use these to override the rules of operator precedence in a mathematical expression
parentheses
__________ are used to translate each source code instruction into the appropriate machine language instruction
compilers
The C++ language requires that you give variables names that indicate what the variables are used for
False

Which of the following best describes an operator?
An operator allows you to perform operations on one or more pieces of data
An integrated development environment typically consists of
all of the above
The only difference between the GET function and the insertion operator (<< , >>) is that the GET reads the first character type even if it's a space, tab, or enter key
True
Characters or symbols that perform operations on one or more operands are
operators
Escape sequences are always stored internally as a single character

null terminator
In programming, the terms line and statement, always mean the same thing
False
In any program that uses the cin object, you must include

False
___________ represents storage locations in a computers memory
variables
At the heart of a computer is a CPU, the CPUs job is

A variable called "average", should be declared as an integer data type because it will probably hold data that holds decimal places
False
Besides decimal, two other number systems you might encounter in a C++ program are
hexadecimal and octal
This manipulator is used to establish a field width for the value immediately following it
