schepotkina [342]

Answer:

The solution code is written in Python 3:

count = 0
totalAge = 0
group1_count = 0 #age < 10
group2_count = 0 #age 10 - 20
group3_count = 0 #age 20 - 40
group4_count = 0 #age > 40
group1_total = 0 #subtotal age <= 10
group2_total = 0 #subtotal age 11 - 20
group3_total = 0 #subtotal age 21 - 40
group4_total = 0 #subtotal age > 40
age = int(input("Input an age: "))
youngest = age
oldest = age
while(age != -1):
count += 1
totalAge += age
if(age <= 10):
group1_count += 1
group1_total += age
elif(age <= 20):
group2_count += 1
group2_total += age
elif(age <= 40):
group3_count += 1
group3_total += age
else:
group4_count += 1
group4_total += age
if(youngest > age):
youngest = age
if(oldest < age):
oldest = age
age = int(input("Input an age: "))
totalCustomer = count
avgAge = totalAge / count
rangeAge = oldest - youngest
avgAgeGroup1 = group1_total / group1_count
avgAgeGroup2 = group2_total / group2_count
avgAgeGroup3 = group3_total / group3_count
avgAgeGroup4 = group4_total / group4_count
print("The total number of customers: " + str(totalCustomer))
print("Total number of customer in Group 1 (<=10): " + str(group1_count))
print("Total number of customer in Group 2 (11 - 20): " + str(group2_count))
print("Total number of customer in Group 3 (21 - 40): " + str(group3_count))
print("Total number of customer in Group 4 (> 40): " + str(group4_count))
print("Average age for all customer: " + str(avgAge))
print("Youngest age: " + str(youngest))
print("Oldest age: " + str(oldest))
print("The range of age: " + str(rangeAge))
print("Average age for group 1 (<=10): " + str(avgAgeGroup1))
print("Average age for group 2 (11 - 20): " + str(avgAgeGroup2))
print("Average age for group 3 (21 - 40): " + str(avgAgeGroup3))
print("Average age for group 4 (> 40): " + str(avgAgeGroup4))

Explanation:

Firstly, create the counter variables (e.g. count, group1_count, group2_count etc ) to track the total number of customer and number in each age group. Besides, create variables to hold the value of total of age and sub-total of each age group (Line 1 - 10). We presume there are only four age groups.

Next, prompt user to input the first age (Line 12)

Create variable youngest and oldest to track the lowest and highest age (Line 13 -14). At the moment, set the first input age as value of youngest and oldest.

Create a while loop with sentinel value -1 (Line 16). Within the loop, track the customer occurrence by incrementing counter variables by one (Line 17, 21, 24, 27 & 30). At the same time, add the current input age to totalAge and to group total (Line 18, 22, 25, 28, & 31).

If the current youngest value is bigger than the current input age, we set the current age to youngest (Line 33- 34).

If the current oldest value is smaller than the current input age, we set the current age to oldest (Line 36- 37).

After terminating the loop with -1, calculate the average age for all customers and for each age group and the range of age (Line 42- 48)

At last, display all the required calculation results using print function (50 - 62)

Create two classes. The first, named Sale, holds data for a sales transaction. Its private data members include the day of the m

olya-2409 [2.1K]

Answer:

A C++ program was used in creating two classes. the code is stated below.

Explanation:

Solution

The C++ program is executed below:

#include<iostream>

using namespace std;

//declare class (will be define later)

class Salesperson;

//class Sale

class Sale

{

//private members of class

private:

string day;

double amtOfSale;

int salesPersonId;

//public methods

public:

//constructor that takes day,amount of sale and salesPersonId as parameters

Sale(string date,double sale,int id)

{

//set the private members to the initial values passed

day=date;

amtOfSale=sale;

salesPersonId=id;

}

//declare a friend function that takes objects of the two classes as parameters

friend void display(Sale,Salesperson);

};

//define class Salesperson

class Salesperson

{

//private members of the class

private:

int salesPersonId;

string lastName;

//public methods

public:

//constructor that takes name and id as parameters

Salesperson(int id,string name)

{

//set the members of the class with the parameters passed

salesPersonId=id;

lastName=name;

}

//declare a friend function that takes objects of the two classes as parameters

friend void display(Sale,Salesperson);

};

//define the friend funtion

void display(Sale saleObj,Salesperson personObj)

{

//display the sales info using the objects of the two classes

cout<<"\nSale #"<<saleObj.salesPersonId<<" on "<<saleObj.day<<" for $"<<saleObj.amtOfSale<<" sold by #"<<personObj.salesPersonId<<" "<<personObj.lastName;

}

int main()

{

//create object for Sale class and pass default values

Sale sObj1("12/25/2016",559.95,103);

//create object for Salesperson class and pass default values

Salesperson pObj1(103,"Woods");

//create another object for Sale class and pass default values

Sale sObj2("11/15/2016",359.95,106);

//create another object for Salesperson class and pass default values

Salesperson pObj2(106,"Hansen");

//using the friend function dislay the sales info

display(sObj1,pObj1);

display(sObj2,pObj2);

return 0;

}
