Having trouble with a template

[Whovian]

Gosh, I'm about to sound like a total idiot.

Why isn't this code working?

#include <iostream>
using namespace std;

template <typename T>
void swap(T& a,T& b)
{
    T temp = a;
    a = b;
    b = temp;
}

int main()
{
    string a = "World!";
    string b = "Hello, ";
    swap<string> (a,b);
    cout << a << b << endl;
}

My IDE says "call to swap is ambiguous."

Correct me if I'm wrong, but shouldn't it be 'World!' and 'Hello, '? I think you need to use 's, not "s.

Take out the using namespace std

Oh! Name conflict! Thanks!

Did your compiler not tell you something like this (i.e where it found conflicting
function names)??

Ahaanomegas, I'm correcting you because you're wrong. "s are used for strings, 's are used only for a single char.

string myName = "PaulthePenguin";
char firstInitial = 'p';
