Question

Purpose: To familiarize yourself with variables and arithmetic.

Directions: Convert the following problems below to c++ equivalent code. Each problem should be done within the same file and all within the same main function. After each step is performed the user should be shown the updated value that was changed. Turn in the finished c++ (.cpp) file for problem 0-6 and the image file for problem 7. Remember to reset or use unique variables for each problem (you cannot declare a variable by the same name twice). In each problem, the user will enter a number(s) on the first step only.

Problem 1-:

Part 1
Take any 2 digit number from 31 to 99. (You do not have to check the numbers just assume the user will enter a valid number so long as you tell them to).
Store an extra copy of this number for later
3. Add 82 to the number.
4.    Remove the hundreds place from your number (by modulus operation)
5. Add 1 to the number.
6.   Subtract this from your original number (stored in step 2).
7.    Output the result obtained

Part 2

Take a random number from the user
Multiply the number by 4
Add 1 to the number
Multiply by the original number that the user input
Subtract the original number away
Take the square root of the number (you can use cmath’s sqrt function)
Divide the number by 2
The result should be the original number

Part 3

Get a random number from the user
Remember the original number
Add 3 to the number
Double the number
and then multiply by 5.
Knock off the last digit (remove the 1’s place)
Finally remove the original number
What is the result?

Problem 2-:

Part 1

1: Have the person write down any three digits number with decreasing digits (432 or 875).
2: Reverse the number you wrote in #1.
3: Subtract the number obtained in #2 from the number you wrote in #1 (#1 - #2)
4: Reverse the number obtained in #3
5: Add the numbers found in #3 and #4
What is the answer?

Part 2

For this problem I want you to draw out a flow chart to illustrate the logic. You may use word, DIA, or any other software you choose but be specific on the symbols used to illustrate this problem. If you use hand drawn, make sure the paper is unlined and that your picture of it is clear and legible. Please submit this problem as an image file
Take any random 2 digit number
Divide the number by 2

Add 17 to the number
If the first digit (10’s place) of the number is greater than the last than add the first digit to the number, otherwise add the second digit (1’s place)
If the number is greater than 21 subtract the product of the 2 digits.
Repeat this until the number is less than 21
Output the results of the number

Answer 1

Thanks for the question. Please post only 1 question at a time. Due to time limit we cannot address all the questions. Also , per Chegg policy, we are limited to answer only the first question and its sub parts.

For the set of questions, I have solved Question 1 and all the 3 parts.

Please post question 2 in a sepearate post and I will be able to assist you in that as well.

thanks for understanding.

Here are the code for the 3 parts.

====================================================================

// Problem 1 : Part 1

# include <iostream>

using namespace std;

int main(){

               

                int num; int copyNum;

               

                cout<<"Please enter a 2 digit number: "; cin >> num;

                copyNum = num ;

               

                num += 82 ; // add 82

                num %= 100; // remove the hundreds place from the number

                num += 1; // add 1

               

                int result = copyNum - num;

               

                cout<< "Result : " << result << endl;

               

}

====================================================================

// Problem 1 : Part 2

# include <iostream>

# include <cmath>

using namespace std;

int main(){

               

                int randomNum; int copy;

               

                cout << "Enter a random number : " ; cin >> randomNum ;

               

                copy = randomNum;

               

                randomNum = randomNum * 4;

                randomNum = randomNum + 1;

               

                randomNum = randomNum * copy ;

               

                randomNum = randomNum - copy ;

               

               

                double sqRoot = sqrt ( randomNum );

               

                sqRoot = sqRoot / 2;

               

                cout <<"Result : " << sqRoot << endl ;

               

}

// Problem 1 : Part 3

# include <iostream>

# include <cmath>

using namespace std;

int main(){

               

                int randomNum; int copy;

               

                cout << "Enter a random number : " ; cin >> randomNum ;

               

                copy = randomNum;

               

                randomNum = randomNum + 3;

               

                randomNum = randomNum + randomNum;

               

                randomNum = randomNum * 5;

               

                randomNum = randomNum/10; // knock off the first place

               

                randomNum = randomNum - copy ;

               

                cout <<"Result : " << randomNum << endl;

}
