Programming & Computer Science Answers

There are following two major issues associated with cpp programs:

• When a program is terminated, the entire data is lost.
• If you have to enter a large number of data, it will take a lot of time to enter them all in
• the different programs.

Suggest a solution and elaborate the same with the help of suitable examples. 

Smith is a course instructor of cpp programming and currently he is teaching conversions to his students. He started with the basic programs and now he want to introduce some complex problems. Before starting the complex problems, he wants to start with high difficulty level problem, such as: counting the digits of a number. Help Mr. Smith to write a program which will accept one integer argument and returns count of digits of that argument using class to class conversion. 

Create a class: “Palindrome” with private data members: upper_limit (int), lower_limit (int) and parameterized constructor, which initializes the values of both data members. Apart from initialization, this constructor also displays the count of palindrome numbers from upper_limit to lower_limit. [Example: upper_limit:50, lower_limit:10, count of palindrome numbers is: 4(11 , 22, 33 and 44), also make sure the value of upper_limit should be greater than lower_limit].

Create a class: “Prime” with private data members: upper_limit (int), lower_limit (int) and parameterized constructor, which initializes the values of both data members. Apart from initialization, this constructor also displays the count of prime numbers from upper_limit to lower_limit. [Example: upper_limit:15, lower_limit:10, count of prime numbers is:2(11 and 13), also make sure the value of upper_limit should be greater than lower_limit].

Create a program that will compute the total

bill of the customer. The program will input

item purchased, quantity, price and cash 

given by the customer. It will display the 

total bill and the change of the customer if

the cash is greater than the total bill. If 

the customer reaches 1000 pesos, he/she will

avail 30% discount of his/her total bill. 

Use if else statement and repetition structure

to display the "Do you want to try again? Y/N?

Write a program, which has two classes. One is Date having members (day, month and year) and the other is Employee. The Employee has a Date class as member as each employee has Date of Joining, Date of Birth, etc. Determine if an employee joined the organization within last five years if the current year is 2012. Determine if an employee has age less than 40 years.

Create a calculator for complex number by creating a class of complex number with overloading all operators in it.(Operators: ++,--,+,-,/,*,>>,<<)

Triplet Sum

Given an array n integers, find and print all the unique triplets (a, b, c) in the array which give the sum K. (a+b+c=K).Input

The first line of the input will be space separated integers, denoting the elements of the array. The second line of the input will be an integer denoting the required sum KOutput

The output should be multiple lines, each line containing a unique triplet. The elements of the triple must be sorted in increasing order and all the triplets printed must be sorted in increasing order. Print "No Matching Triplets Found" if there are no triplets with the given sum.Explanation

When the given array is [0, 1, 2, 3, 5, 7, 13, 17, 19, 19] and the required sum is 22, the triplets (0, 3, 19), (0, 5, 17), (1, 2, 19), (2, 3, 17) and (2, 7, 13) have the given sum 22.

Sample Input 1

0 12 17 8 9 21

29

Sample Output 1

(0, 8, 21)

(0, 12, 17)

(8, 9, 12)

Sample Input 2

0 1 2 3 5 7 13 17 19 19

22

Sample Output 2

(0, 3, 19)

(0, 5, 17)

(1, 2, 19)

(2, 3, 17)

(2, 7, 13)

Non-Adjacent Combinations of Two Words

Given a sentence as input, find all the unique combinations of two words and print the word combinations that are not adjacent in the original sentence in lexicographical order.Input

For example, if the given sentence is "python is a programming language", the possible unique combination of two are (a, is), (a, language), (a, programming), (a, python), (is, language), (is, programming), (is, python), (language, programming), (language, python), (programming, python). Out of these the combinations, (a, is), (a, programming), (is, python), (language, programming) are not valid as they contain words that are adjacent in the given sentence. So the output should be

a language

a python

is language

is programming

language python

programming python
