Program Plan Intro
Percentage Calculation
Program Plan:
ADT interface filename: “Percent.h”
- Include required header files.
- Define a class “Percent”.
- Declare function for overload operator “==” and “<”.
- Declare default constructor for “Percent” class.
- Declare a constructor for “Percent” class with one integer parameter.
- Declare function for input overload operator and output overload operator.
- Declare function for binary overload operators “+”, “-” and “*”.
- Declare a member variable “value”.
ADT implementation filename: “Percent.cpp”
- Include required header files.
- Define default constructor for “Percent” class.
- Here assign the value of “value” to “0”.
- Define constructor for “Percent” class with one integer parameter “percentValue”.
- In this constructor, assign “value” to “percentValue”.
- Define a function for overload operator “<”.
- This function is used to check whether the first percent is less than second percent or not.
- Define a function for overload operator “==”.
- This function is used to check whether the two percent’s are equal or not.
- Define a function for input operator “>>”.
- Define a function for input operator “<<”.
- Define a function for binary overload operator “+” to compute the sum of two percentages.
- In this function, create an object “sum”.
- Then compute the addition of two percent’s.
- Finally returns the result of addition.
- Define a function for binary overload operator “-” to compute the subtraction of two percentages.
- In this function, create an object “s”.
- Then compute the subtraction of two percent’s.
- Finally returns the result of subtraction.
- Define a function for binary overload operator “*” to compute the multiplication of one percent and an integer value.
- In this function, create an object “m”.
- Then compute the multiplication of one percent and an integer value.
- Finally returns the result of multiplication.
Application filename: “main.cpp”
- Include required header files.
- Define main function.
- Create two objects “percent1” and “percent2” from “Percent” class.
- Create an object “percent3” with one integer parameter “10”.
- Declare an integer variable “intValue”.
- Read the percentage 1 and percentage 2 from user.
- Check the two percentages using “==” operator.
- Check the two percentages using “<” operator.
- Create an object “sumPercent” from “Percent” class.
- Then compute and display sum of two percentages.
- Create an object “subPercent” from “Percent” class.
- Then compute and display difference of two percentages.
- Display percentage 3 from assigned value.
- Read an integer from user to multiply with a percentage 3.
- Finally compute and display the multiplication of “percent3” and a user entered integer value.

Based on the given problem, create an algorithm and a block diagram, and write the program code:
Function: y=xsinx
Interval: [0,π]
Requirements:
Create a graph of the function.
Show the coordinates (x and y).
Choose your own scale and show it in the block diagram.
Create a block diagram based on the algorithm.
Write the program code in Python.
Requirements:
Each step in the block diagram must be clearly shown.
The graph of the function must be drawn and saved (in PNG format).
Write the code in a modular way (functions and the main part should be separate).
Please explain and describe the results in detail.

The table includes columns about customer location such as city, state, and country. You want to retrieve the first 3 letters of each country name. You decide to use the SUBSTR function to retrieve the first 3 letters of each country name, and use the AS command to store the result in a new column called new_country. You write the SQL query below. Add a statement to your SQL query that will retrieve the first 3 letters of each country name and store the result in a new column as new_country.arrow_forwardWe are considering the RSA encryption scheme. The involved numbers are small, so the communication is insecure. Alice's public key (n,public_key) is (247,7). A code breaker manages to factories 247 = 13 x 19 Determine Alice's secret key.
