Answer the following statements true (T) or false (F)

1. A C++ declaration introduces only an identifier's spelling and specifies its type.
2. A C++ declaration is a definition that also allocates storage for an identifier's value
(or function's body etc.).
3. The range of values for an int variable is from about 0 to +2 billion.
4. The names x, y, and z are satisfactory variable names for the lengths of the legs
and hypotenuse of a triangle.
5. In C++ you can assign an expression of type int to a variable of type double with
no problem.

1. True.
A declaration introduces the spelling and type, whereas a definition is a declaration that also allocates memory.
2. True.
A declaration introduces the spelling and type, whereas a definition is a
declaration that also allocates memory.
3. False:
The correct range is about –2 Billion to +2 Billion.
4. False.
Names should communicate to the human reader the meaning of the value.
These identifiers do not communicate the meaning of their values..
5. True.
Assignment from an integer type to a floating point type can lose
information and should be avoided. Some compilers will warn, others may give an error
message, but you should avoid this.
