saving variables in a string
#include <iostream>
#include <string>
using namespace std;
// you need to tell the compiler where the entry point is
int main()
{
string first;
string middle; // here you have your variables declared
string last;
cout<<"Enter your first name: ";
getline(cin,first); // this works and you can also get inpout like cin>>first;
cout<<"Enter your middle name: ";
getline(cin,middle);
cout<<"Enter your last name: ";
getline(cin,last);
first="Henry"; //here you have the same variable declared twice
middle="Louis"; // either get rid of all strings and make it middle = "Louis"
last="Aaron"; //or declare different variables like first1, or something else
string name;
name = first + " " + middle + " " + last;
cout << "Name is: " << name << endl;
// dont forget
return 0;
} //everything else should compile, but I'm not debugging it for you
