Question

***C++ 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.

Answer 1

C++ code:

#include<iostream>
#include<list>
#include<vector>
using namespace std;
void fact()
{
   int n,val=1;
   cout<<"Enter a number:";
   cin>>n;
   for(int i=2;i<=n;i++)
   {
       val*=i;
   }
  
   cout<<"Factorial of "<<n<<" is "<<val<<endl;
}

int sum(list<int> list1)
{
   int s=0;
for (list<int>::iterator i=list1.begin(); i!=list1.end(); i++)
s+= *i;
return(s) ;

}

int med(list<int> list1)
{
   int s=0;
for (list<int>::iterator i=list1.begin(); i!=list1.end(); i++)
{
    if(s==list1.size()/2)
        return(*i);
    s++;
   }
return(s) ;

}

int main()
{
   int flag=1,option;
list<int> list1;
list1.push_back(3);
list1.push_back(4);
list1.push_back(84);
list1.push_back(5);
list1.push_back(2);
list1.push_back(47);
list1.push_back(7);
list1.sort();

do
{
    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>>option;
    switch(option)
    {
        case 1:   fact(); break;
       
        case 2:   cout<<"Median:"<<med(list1)<<endl;break;
       
        case 3:cout<<"Average:"<<sum(list1)/list1.size()<<endl;break;
       
        case 4:   cout<<"Maximum item in list:"<<list1.back()<<endl;break;
       
        case 5:   cout<<"Minimum item in list:"<<list1.front()<<endl;break;
       
        case 6:   flag=0;break;
         
   }
}while(flag);
  
}

Output:
