A quick problem reguarding strings

[thebawt]

Hi there, I am very new to C++ and I am encountering a problem in my work. I have a program that Adds, Removes, Sorts, Finds, and Displays character inputs, such as names. The program takes first and last names successfully. Where my issue comes in though is I am trying to add in the functionality of having it format the inputted names as per this example when displayed:

Input: FirstName LastName
Output: LastName, FirstName


Here is my code, any help would be appreciated!

Thanks,
thebawt

#include<iostream>
#include<sstream>
#include<string>
using namespace std;
const int SIZE=10;
void getNames(string names[], int& n)
{
     n=0;
     do
     {
         cout<<"Enter a name, quit to stop: ";
         getline(cin, names[n]);
         if(names[n]=="quit") 
         break;
             }
             while(++n<SIZE);
             
     }

 void display(string a[], int s)
{
      for(int i=0; i<s; i++)
      {
              cout<<a[i]<<endl;
      }
}


 void sort(string a[], int s)
{
      for(int i=1; i<s; i++)
      for(int j=0; j<s-i; j++)
      {
              if(a[j]>a[j+1])
              swap(a[j], a[j+1]);
      }
}


int find(string a[], int s)
{
    string name;
    cout<<"Enter the name to find: ";
    cin>>name;
    for(int i=0; i<s; i++)
    {
            if(a[i]==name)
            return i;
    }
            return s;
}


void remove(string a[], int& s)
{
     int i;
     i=find(a, s);
     if (i==s)
     cout<<"There is no such name!";
     else
     {
         for(int j=i; j<s; j++)
         {
                 a[j]=a[j+1];
         }
         s--;
     }
}
char getRes()
{
     char res;
     cout<<endl;
     cout<<" (A)dd // (S)ort // (F)ind // (R)emove // (D)isplay // (Q)uit"<<endl
     <<"Choice: ";
     cin>>res;
     return res;
}


main()
{
      string a[SIZE];
      int n;
      char res;
      do
      {
          res=getRes();
          if(res=='Q')
            break;
          switch(res)
          {
              case 'A': getNames(a, n); break;
              case 'D': display(a, n); break;
              case 'S': sort(a, n); break;
              case 'F': cout<<find(a, n); break;
              case 'R': remove(a, n); break;            
          }
      }while(true);
      system("pause");
}

Do you understand what you are writing? For example what does mean line

str.substr(0, 0)

in function getNames?

Ahh, oops, that was me toying around and I forgot to remove it, ill edit the post.

These are the two lines (17 and 18) I accidentally left in.

str.find(' ', 0)
str.substr(0, 0)

Edit:
I mostly understand what I have wrote so far, however, as part of my current assignment, I am having trouble understanding how to format the names, or where to even put the conversion in my program.

[vlad from moscow]

The function has no the closing brace.

[thebawt]

I'm sorry, I don't understand what you mean by that.

[vlad from moscow]

What I wrote is what I mean. You formated the code badly.
EDIT: As for your problem then you are entering a string of two words but in all other functions you are entering only one word and trying to compare it with a string of two words.
That is using getline you entered two words. But using operator >> you entered only one word. It is obvious that two words can not be equal to one word.

Perhaps an example? Keep in mind I am very new. I started a class less than a month ago.
