Question

Greetings,

I am having problems with the following question. When i do it, it seems to go in infinity.

Problem 1. Use a nested loop to print out the following:

********

*******

******

*****

****

***

**

*

I'm also having issues with the following problem.

Problem 2. Comprehensive programming: (file I/O, if…else, for loop, output manipulators)

Cheap Chirps is a pet store specializing in pet birds. The store needs a new inventory program and has hired you to develop the program. Write a C++ program that will:

1.Read an inventory list of birds from a data file called BIRD.txt. The file contains information on bird species in the store. There are four lines in the file. Each line of the file has type of bird (no larger than 20 characters), price of the bird, and the consumed food in pounds monthly. Use for loop to read the related information.

BIRD.txt

MACAW 2,500.00 20

AMAZON 550.75            15

COCKATIEL 123.50 2

PARAKEET 45.50 1

2.Your program will find if the bird is a large hookbill or a small hookbill (Large hookbills eat 15 or more pounds of food a month.) Use a character 'L' to represent a large hookbill and an 'S' to represent a small hookbill.

3.Your program will also calculate the average price of a bird and the average amount of food eaten in one month.

4.Print the output so that it is organized as below. Note the values for the averages are printed to two decimal places. All printing is done in the main function.

BIRD                           PRICE          FOOD           HOOKBILL

----------------------------------------------------------------------------

MACAW                   2500.00                 20                         L

AMAZON                   550.75                 15                         L

COCKATIEL              123.50                   2                         S

PARAKEET                  45.50                   1                         S

The average price is: 804.94

The average food is: 9.50

Explanation / Answer

program 1:

/**C++ program that prints a patters of stars*/
#include<iostream>
using namespace std;
int main()
{

   //set a character star
   char star='*';
   //set COLUMNS=8
   int COLUMNS=8;
   //set size
   int size=COLUMNS;

   //run outer loop for 8 times
   for(int index=1;index<=COLUMNS;index++)
   {

       for(int index=1;index<=size;index++)
           cout<<star;

       cout<<endl;
       //decrement the size of inner loop by one
       size=size-1;
   }

   system("pause");
   return 0;
}
sample output:
********
*******
******
*****
****

Program 2:
/**C++ program that reads a text file BIRD.txt which of
four lines . Each line contains name, price and food.
The program reads the text and prints the files and finds
the HOOKBILL and avaerage price and averae food */
#include<iostream>
#include<fstream>
#include<iomanip>
using namespace std;

//create a strucure Bird
struct Bird
{
   //name of size 20 characters long
   char name[20];
   //declare price
   double price;
   //declare food
   int food;
};

int main()
{
   const int NUM_LINES=4;
   struct Bird bird[NUM_LINES];

   ifstream fin;
   fin.open("BIRD.txt");

   if(!fin)
   {
       cout<<"File doesnot exist"<<endl;
       return 1;
   }
   //declare two double type variables and set to zero
   double totalPrice=0;
   double totalFood=0;

   for(int index=0;index<NUM_LINES;index++)
   {
       //read name , price and food
       fin>>bird[index].name>>bird[index].price>>bird[index].food;
       //Add price to total price
       totalPrice+=bird[index].price;
       //Add price to totalFood
       totalFood+=bird[index].food;
   }

   cout<<setw(10)<<"BIRD"<<setw(10)<<"PRICE"<<setw(10)<<"FOOD"<<setw(10)<<"HOOKBILL"<<endl;
   cout<<"-------------------------------------"<<endl;
   for(int index=0;index<NUM_LINES;index++)
   {
       //read name , price and food
       cout<<setw(10)<<bird[index].name<<setw(10)<<bird[index].price<<setw(10)<<bird[index].food;

       //Set HOOKBILL as L if food is greater than 15
       if(bird[index].food>=15)
           cout<<setw(10)<<"L"<<endl;
       else
           //otherwise set HOOKBILL to S
           cout<<setw(10)<<"S"<<endl;

   }

   //print average price
   cout<<"The average price is "<<setprecision(5)<<totalPrice/4.0<<endl;
   //prit average food
   cout<<"The average food is "<<setprecision(5)<<totalFood/4.0<<endl;

   system("pause");
   return 0;
}

Sample output:

      BIRD     PRICE      FOOD HOOKBILL
---------------------------------------------------------
     MACAW      2500        20         L
    AMAZON    550.75        15        L
COCKATIEL     123.5         2       S
PARAKEET      45.5         1         S
The average price is 804.94
The average food is 9.5
