Question

***C++ Program ONLY***

Menu driven program

First load an array(lists) with the values 3, 4, 84, 5, 2, 47, and 7 in this order

Then sort the array(list)

Create a program with a menu, with choices 1 for factorial (single value, which everyone will use 20!), 2 for median value , 3 for average, 4 for maximum, 5 for minimum, and 6 to end the program.

Use a do loop (not while)

Python does not have a Do loop, so instead use

while True:

where for quit you can issue the break command

Use a switch statement inside the loop to make your choice of 1, 2, etc. for Java and C++ and an if/elif in Python

You also need to to include a screen shot of your menu on the screen in your submission.

To make for a better looking output, store the function (Factorial, Median, Maximum, etc.) in a string array(list) and your answer in a numeric array(list). (two arrays) Then in the exit module (choice 6) print out your answers. Note this involves running choices 1-6 in order.

***C++ Program ONLY***

Answer 1

Solution:

Code:

Output:

Copyable code:

/*Include necessary headers*/

#include<iostream>

#include<list>

#include<vector>

using namespace std;

/*Function definition for factorial*/

void factorial()

{

/*Declaration and initialization*/

int n,number=1;

/*Prompt and get the value*/

cout<<"Enter a value:";

cin>>n;

//Loop

for(int i=2;i<=n;i++)

{

//calculation

number*=i;

}

//Print the result

cout<<"Factorial of "<<n<<" is "<<number<<endl;

}

/*Function definition for total value of list*/

int tot(list<int> list1)

{

/*Declaration and initialization*/

int ini=0;

//Loop

for (list<int>::iterator i=list1.begin(); i!=list1.end(); i++)

ini+= *i;

return(ini) ;

}

/*Function definition for median value*/

int median(list<int> list1)

{

/*Declaration and initialization*/

int ini=0;

//Loop

for (list<int>::iterator i=list1.begin(); i!=list1.end(); i++)

{

if(ini==list1.size()/2)

return(*i);

ini++;

}

return(ini) ;

}

/*Function definition for main*/

int main()

{

/*Declaration and initialization*/

int temp=1,ch;

list<int> arraylist;

arraylist.push_back(3);

arraylist.push_back(4);

arraylist.push_back(84);

arraylist.push_back(5);

arraylist.push_back(2);

arraylist.push_back(47);

arraylist.push_back(7);

arraylist.sort();

/*do...while loop*/

do

{

/*Prompt and get the value*/

cout<<"Enter 1 for factorial"<<endl;

cout<<"Enter 2 for median"<<endl;

cout<<"Enter 3 for average"<<endl;

cout<<"Enter 4 for maximum"<<endl;

cout<<"Enter 5 for minimum"<<endl;

cout<<"Enter 6 to end program"<<endl;

cin>>ch;

//Switch case

switch(ch)

{

case 1: factorial(); break;

case 2: cout<<"Median:"<<median(arraylist)<<endl;break;

case 3:cout<<"Average:"<<tot(arraylist)/arraylist.size()<<endl;break;

case 4: cout<<"Maximum item in list:"<<arraylist.back()<<endl;break;

case 5: cout<<"Minimum item in list:"<<arraylist.front()<<endl;break;

case 6: temp=0;break;

}

}

while(temp);

}
