Chapter 3, Problem 19E

Explanation of Solution

Given: The expressions ( 9 + 3 + “cat� ) and ( “cat� 3 + 9 ).

To find: The result of the expressions ( 9 + 3 + “cat� ) and ( “cat� 3 + 9 ) and provide the reason why this output is obtained.

Solution:

The result of ( 9 + 3 + “cat� ) expression will be 12cat of type string because the “+� operator between 9 and 3 will behave as arithmetic operator. Hence, the result of 9+3+“cat� will be 12+“cat�. After that, the “+� operator between 12 and “cat� will behave as concatenation operator. Hence, the result of 12+“cat� will be “12cat�.
