Compare and Contrast counters and accumulators. List two uses of each? - ANSA
counter is a variable that increments by a fixed value for example x+= 1, would add 1
to x everyone time the loop is run, whereas an accumulator is a variable that
increments by varying amount, say x += y, in this case it would change by varying
amount each time y is changed. Yet they both serve as counting variables.
Computer Programming Chp6 Critical Thinking Questions - ANS
Explain the difference between a while statement and a do-while statement? - ANSA
while statement first assesses the condition then compile the commands, whereas
the do-while statement runs the commands once then assesses the condition.
True or False:
A counter is incremented by a constant amount. - ANSTrue
True or False:
A while statement iterates once before evaluating the condition. - ANSFalse, a do-
while statement iterates once before evaluating the condition.
True or False:
An accumulator signifies that a loop should stop iterating. - ANSFalse, a Sentinel
value indicates that a loop should stop iterating.
True or False:
Sentinel values must always be the value -1. - ANSFalse, Sentinel values can be set
to anything.
True or False:
String variables are primitive data types. - ANSFalse, string variable is not a primitive
data type.
True or False:
Strings are compared using relational operators such as >. - ANSFalse, the strings
are compared using compareTo() method
True or False:
The first character of a string has a index position 1. - ANSFalse, the first character
of a string has a index position 0.
