Definitions - A set of instructions written in a specific programming language that
causes a computer to perform a specific task is referred to as COMPUTER
PROGRAM. RAW FACTS are referred to as date while PROCESSED FACTS are
referred to as information. A language with strict grammar rules, symbols and
special words used to construct a computer program is a PROGRAMMING
LANGUAGE. A step-by-step list of instruction that, when carried out, produces a
solution to a problem is referred to as ALGORITHM.
Given the algorithm in the leap year case study
Divide the year by 4 and if the remainder isn't 0Return false (The year is not a leap
year)Otherwise, divide the year by 100 and if the remainder isn't 0,Return true
(The year is a leap year)Otherwise, divide the year by 400 and if the remainder
isn't 0,Return false (The year is not a leap year)Otherwise, Return true (the year is
a leap year)
Decide whether the following years are leap years:
a. 1900
b. 2000
c. 1996
d. 1998 - a. 1900 No
b. 2000 Yes
c. 1996 Yes
d. 1998 No
,Given the algorithm from the leap year case study with the lines numbered as
follows:
1. Divide the year by 4 and if the remainder isn't 0
2. Return false (The year is not a leap year)
3. Otherwise, divide the year by 100 and if the remainder isn't 0,
4. Return true (The year is a leap year)
5. Otherwise, divide the year by 400 and if the remainder isn't 0,
6. Return false (The year is not a leap year)
7. Otherwise, Return true (the year is a leap year)
Indicate which line of the algorithm tells you whether the date is a leap year in
each of the following cases:
a. 1900 Line =
b. 1945 Line =
c. 1600 Line =
d. 1492 Line =
e. 1776 Line = - a. 1900 Line = 6
b. 1945 Line = 2
c. 1600 Line = 7
d. 1492 Line = 4
e. 1776 Line = 4
How would you extend the leap year algorithm to tell you also when a year is a
millennium year (a multiple of 1000)? - Divide by 1000 and see if the remainder is
0.
LESSON 2 -
, Mark the following identifiers as either valid or invalid.
a. theDog e. DVD_ROM
b. all - In - On f. Elizabeth_the_2nd
c. const g. 2morrow
d. recycling h. page# - a. valid
b. invalid (hyphens not allowed)
c. invalid (reserved words not allowed)
d. valid
e. valid
f. valid
g. invalid (must begin with a letter)
h. invalid (# is not allowed)
Write a single output statement that outputs the following three lines:
He said, "How is that possible?"
She replied, "Using manipulators."
"Of course!" he exclaimed. - Note that the \" escape sequence is needed in six
places here:
cout << "He said, \"How is that possible?\"" << endl
<< "She replied, \"Using manipulators.\"" << endl
<< "\"Of course,\" he exclaimed!" << endl;
What is the result of each of the following expressions?
a. 27 + - 7
b. 27.0 + 8..0 - 7.0
