Please, submit your homework electronically using the "submit" system.
Please try to follow the "good programming" conventions
we discussed in class. Write modular code and include all
of your functions in the same CPP file as your main.
(HW_6_1.cpp/exe) A
palindrome is a number or a text
phrase that reads the same backwards as forwards.
For example, each of the following five-digit
integers is a palindrome:
{12321, 55555, 45554, 11611}.
Write a program that reads in a five-digit
integer and determines whether it is a palindrome.
(Hint: Use the division and modulus
operators to separate the number into its
individual digits. E.g., the left-most 1 in
12321, could be extracted by: 12321/104 = 1,
and the remaining 4 digits are obtained by:
12321%104 = 2321. This remainder is
then processed in a similar fashion.)
Sample Run:
%> (Palindrome Test) Enter a five-digit integer:
%> 12321
%> This number is a Palindrome
%> Try another one (y/n)?
%> y
%> (Palindrome Test) Enter a five-digit integer:
%> 12341
%> This number is NOT a Palindrome
%> Try another one (y/n)?
%> n
%> Bye!
(HW_6_2.cpp/exe) (Binary-to-decimal
conversion)
Collect from the user an integer containing only 0's
and 1's (i.e., a binary integer) and print its
decimal equivalent. (Hint: Use the modulus
and division operators to pick off the
binary number's digits one at a time from right
to left. Just as in the decimal number system
where the rightmost digit has a positional value
of 1 and the next digit left has a positional
value of 10, then 100, then 1000, etc., in
the binary number system, the rightmost digit has a
positional value of 1, the next digit left has a
positional value of 2, then 4, then 8, etc. (powers
of 2, Why?) Thus, the decimal number 234 can be
interpreted as 4*1 + 3*10 + 2*100. The decimal
equivalent of the binary 1101 is: 1*1 + 0*2 + 1*4 + 1*8 =
= 1 + 0 + 4 + 8 = 13. Note that you should be
able to convert a binary number of any
length less than 9 digits.
Here is a bit more about interpreting binary numbers.)
Sample Run:
%> (Binary-to-decimal-Converter) Please enter
a binary number (e.g., 10010):
%> 10010111
%> 10010111 (2) <--> 151 (10).
%> Would you like to convert another
number from (2)-base --> (10)-base (y/n)?
%> y
%> 111 (2) <--> 7 (10).
%> Would you like to convert another
number from (2)-base --> (10)-base (y/n)?
%> n
%> Goodbye!
