Which of the following are legal definitions with initializations? (Consider each line to be in a different scope so there is no multiple definition of identifiers.)
a) int count = 0, limit = 19;
b) int count(0), limit(19);
c) int count = 0, limit(19);
d) int limit = 19;
e) int namespace(0);
All are legal except part e) int namespace(0); because namespace is a
keyword. Keywords are reserved so may not be used as an identifier.
Explanation: Note parts a), b), and c). Some authors advocate declaring each identifier in
separate definitions on separate lines, though this takes up more lines. Advocates justify
this by asserting increased readability. The instructor must decide this issue.
