Answer 1

4.4

step 1: The program is as follows:

*********************************************************************************************************************************************

//Lab4 color.cpp
//This program lets the user select a primary color from a menu.
//put your name here
#include<iostream>
#include<string>
using namespace std;

int main()
{
   int choice; //Menu choice should be 1,2 or 3
  
   //Display the menu of choices
   cout << "Choose a primary color by entering its number.\n\n";
   cout << "1 Red\n" << "2 Blue\n" << "3 Yellow\n";
  
   //Get the user's choice
   cin >> choice;
  
   //Tell the user what he or she picked
   if(choice ==1)
   cout << "\nYou picked red.\n";
   else if(choice ==2)
   cout << "\nYou picked blue.\n";
   else
   cout << "\nYou picked yellow.\n";
  
   return 0;
}

**********************************************************************************************************************************

Step 2 : After compilation the output as recorded in the program is :

Run	Menu choice	Current Output	New output
1	1	You picked red.
2	2	You picked blue.
3	3	You picked yellow.
4	0	You picked yellow.
5	99	You picked yellow.

Screen shot of one of the output of the program is

Choose a primary color by entering its number. 1 Red 2 Blue 3 Yellow You picked red.

Step 3: Manipulating the program and adding choice 3 and trailing else the new program is as follows:

***********************************************************************************************************************************

//Lab4 color.cpp
//This program lets the user select a primary color from a menu.
//put your name here
#include<iostream>
#include<string>
using namespace std;

int main()
{
   int choice; //Menu choice should be 1,2 or 3
  
   //Display the menu of choices
   cout << "Choose a primary color by entering its number.\n\n";
   cout << "1 Red\n" << "2 Blue\n" << "3 Yellow\n";
  
   //Get the user's choice
   cin >> choice;
  
   //Tell the user what he or she picked
   if(choice ==1)
   cout << "\nYou picked red.\n";
   else if(choice ==2)
   cout << "\nYou picked blue.\n";
   else if(choice == 3)
   cout << "\nYou picked yellow.\n";
   else
   cout << "You have chosen a wrong choice!!";
  
   return 0;
}

*********************************************************************************************************************

After updation of the program the output is as follows :

Run	Menu choice	Current Output	New output
1	1	You picked red.	You picked red.
2	2	You picked blue.	You picked blue.
3	3	You picked yellow.	You picked yellow.
4	0	You picked yellow.	You have chosen a wrong choice!!
5	99	You picked yellow.	You have chosen a wrong choice!!

4.5

The program of using nasted if/else is as follows:

****************************************************************************************************

//Lab 4 petTag.cpp
//This program determines the fee for a cat or dog pet tag.
//It uses nested if/else statement.
//PUT YOUR NAME HERE
#include<iostream>
#include<string>
using namespace std;
int main()
{
   string pet; //"cat" or "dog"
   char spayed; //'y' or 'n'
  
   //Get pet type and spaying information
   cout << "Enter the pet type (cat or dog): ";
   cin >> pet;
   cout << "Has the pet spayed or neutered (y/n)? ";
   cin >> spayed;
  
   //Determine the pet tag fee
   if(pet == "cat")
   {
       if(spayed == 'y')
       cout << "Fee is $4.00 \n";
       else
       cout << "Fee is $8.00 \n";
   }
   else if(pet == "dog")
   {
       if(spayed == 'y')
       cout << "Fee is $6.00 \n";
       else
       cout << "Fee is $12.00 \n";
   }
   else
       cout << "Only cats and dogs need pet tags. \n";
   return 0;
  
}

******************************************************************************************************************

The output as recorded after compilation and running of the program 7 times is as follows :

Run	Input data	Fee Information	Correct?
1	cat y	4	yes
2	cat n	8	yes
3	cat y	4	yes
4	dog y	6	yes
5	dog n	12	yes
6	dog y	6	yes
7	hamster n	error information	no

Here the error information is : "Only cats and dogs need pet tags."

You can run the program as well and record the output. The screen shot of one of the run of the program is given below

D. E:\Personal Chegg\petTag.exe Enter the pet type <cat or dog>: cat Has the pet spayed or neutered (u/n? UI Fee is $4.00 = ============ ------------ Process exited after 15.44 seconds with return value @ Press any key to continue . . .
