First one passes by reference, which will affect the original object, second one passes by value which will make a copy of the object and only act on that.

For instance:

void func1(int a)
{
    a++;
}

void func2(int& a)
{
    a++;
}

int main()
{
    int a = 0;
    int b = 0;

    func1(a);
    func2(b);

    cout << a << endl; // outputs 0 as the original value is not affected when passed by reference, just a copy which is destroyed after the function exits.
    cout << b << endl; // outputs 1 as func2 passes by reference, changing the original

    return 0;
}
