logical
Write a C++ logical expression that is false if either x or y is equal to 5:
____________________ - Answer-x != 5 && y != 5
True or False? Testing is performed only in the implementation phase of a program's life
cycle - Answer-false
The operators <, ==, >=, and != are examples of ____________________ operators -
Answer-relational
An If-Then-Else-If structure represents a(n) ____________________-way branch -
Answer-multi
A(n) ____________________ expression is an expression composed of logical
(Boolean) values and operations. - Answer-logical
In programming languages that use ____________________ evaluation of a logical
expression, evaluation proceeds in left-to-right order and stops as soon as the final truth
value can be determined. - Answer-short-circuit
