I want to create a function in C++ using cout that has the same as the println function in java. This means that the call should be something like this:
[c]int a=5
println("A string" + a);[/c]
the variable a should have any basic type. What kind of parameter should I have in this case and how would it work?

As larsmans already pointed out, java has overloads on the operator +. So you can concat strings with integer. This is also possible in C++ but not out of the box for all types.
You could use a templated functions like this.
[c]#include <iostream>
using namespace std;
template <typename T>
void printer(T t)
{
cout << t << endl;
}
template <typename T, typename …U>
void printer(T t, U …u)
{
cout << t;
printer(u…);
}
int main()
{
int a=5;
printer("A string ", a);
return 0;
}[/c]
But I would recommend to take a look at boost::format. I guess this library will do what you want.
