Question

The Daily Trumpet newspaper accepts classified advertisements in 15 categories, such as Apartments for Rent and Pets for Sale. Develop the logic for a program that accepts classified advertising data, including a category code (an integer 1 through 15) and the number of words in the ad. Store these values in parallel arrays. Then sort the arrays so that records are sorted in ascending order by category. The output lists each category number, the number of ads in the category, and the total number of words in the ads in the category.

Answer 1

Answer:

#include<iostream>

using namespace std;

#define MA 100

int main()

{

int temp;

int i,j,k;

int advertisementCategoryCode[MA];

int subtotal;

int adwords[MA];

int curCode;

int totalAds;

cout<<"Please enter the total ads: ";

cin>>totalAds;

if((totalAds > 0) and (totalAds <= MA))

{

for (i = 0;i<totalAds;i++)

{

cout<<"Please enter Advertisement Category Code (1 - 15): ";

cin>>advertisementCategoryCode[i];

cout<<"Please enter number of words for the advertisement: ";

cin>>adwords[i];

}

for (i=0;i<totalAds-1;i++)

{

for (j = 0;j<totalAds-1;j++)

{

if (advertisementCategoryCode[j] > advertisementCategoryCode[j+1])

{

temp = advertisementCategoryCode[j];

advertisementCategoryCode[j] = advertisementCategoryCode[j+1];

advertisementCategoryCode[j+1] = temp;

temp = adwords[j];

adwords[j] = adwords[j+1];

adwords[j+1] = temp;

}

}

}

cout<<"\n\n Total Word Counts Sorted By Category Code"<<endl;

k = 0;

while(k<=totalAds-1)

{

subtotal = 0;

curCode = advertisementCategoryCode[k];

while ( (curCode == advertisementCategoryCode[k])&& (k <= totalAds - 1) )

{

subtotal = subtotal + adwords[k];

k = k + 1;

}

cout<<"Category: "<<advertisementCategoryCode[k - 1]<<" "<<"Word Count: "<<subtotal<<endl;

}

}

else

{

cout<<"Number adds requested less than 1 or is too large; ad limit is :"<<MA;

}

return 0;

}

Explanation:

• Use a while loop that runs until the variable k <= (totalAds-1) .
• Assign the current code to the curCode variable.
• Add the words for advertisement and assign it to the subTotal variable.
