Need to get last 2 characters from string
I need to get the last 2 characters from the last name which is input from the keyboard. I am trying to use "thestring.copy(str, x, n). I do not know the length of the name being input. my attempt at the function is
I am using strlen - 2 to find the end of the string and copy from the last 2 characters. I do not know if I am on the right path and also I am getting an error
Here is the code
#include <iostream>
#include <fstream>
#include <cstring>
#include <string>
#include <iostream>
using namespace std;
last.copy(str, strlen -2, 2) |

if (first.length() < 3)
{
cout << "First name must be at least three letters" << endl;
}
else
{
cout << "Enter last name" << endl;
cin >> str;
lastlen = strlen (last);
//cin.getline (last, 20);
//getline (cin, last);

if (last.length() < 2)
{
cout << "Last name must be at least two letters" << endl;
}
else
{
first.resize (3);
last.copy(str, strlen -2, 2)
//last.resize (2);
}
}
cout << first << " " << last << str << endl; //used to check array variables. not part of code
cout << "Your Star Wars name is: " << first << "-" << last << endl;

I figured out how to get the last 2 characters but now need to capitalize just the first letter of the 2. Thanks
