Question

Design a program that allows the user to enter 20 names into a String array. Sort the array in ascending (alphabetical) order and display its contents. Can I get this in C++ Language Flowchart please

Answer 1

In the following C++ program we ask the user to enter 20 names that we store in an array of strings, name[ ].

Then we call the function, sortname() that takes in the array, name[] as the parameter.

In the function we use simple bubble sort to sort the names in the array.

At last we print the names in the sorted order.

FLOWCHART:

CODE:

#include<iostream>
using namespace std;

void sortnames(string name[])
{
   int i,j;
   string temp;
   for(i=0; i<20; i++)
   {
       for(j=0; j<20-i-1; j++)
       {
           if(name[j] > name[j+1])   //if current name is greater than next
           {   //then swap the names
               temp = name[j];
               name[j] = name[j+1];
               name[j+1] = temp;
           }
       }
   }
}
int main()
{
   string name[20];
   cout<<"Enter the 20 names: \n";
   for(int i=0; i<20; i++)
       cin>>name[i];   //input names
   sortnames(name);   //calling the function
   cout<<"\nNames after sorting are:\n";
   for(int i=0; i<20; i++)
       cout<<name[i]<<endl;   //printing the names
  
   return 0;
}

OUTPUT:

Answer 2

I've used a sorting technique known as bubble sorting , you can use any sorting technique to implement sorting .

In bubble sorting in every iteration a position from last gets it's proper value, and if do not perform any swap during a whole iteration then array is sorted so at that time we stop sorting.

I've attached both flowchart and the program for the above question

here is the flowchart:

here is the program code:

#include<iostream>
using namespace std;
int main()
{
string arr[20];
cout<<"enter 20 strings in new lines";
for(int i=0;i<20;i++) // take input of 20 strings
{
cin>>arr[i];
}
// bubble sorting technique is used
for(int i=0;i<20;i++)
{
bool swapbool = false; // this will check if we do not make any swap in an iteration then array is sorted
for(int j=0;j<20-i-1;j++)
{
if(arr[j].compare(arr[j+1])>0)
{
swapbool=true;
swap(arr[j],arr[j+1]);
}
}
if(swapbool==false) // as no change is swapbool so array is sorted
{
break;
}
}
for(int i=0;i<20;i++)
{
cout<<"\n"<<arr[i];
}
}

thanks. I hope it'll help you so please give positive ratings.
