int and float in function overloading

Question

I have two overloaded function like below:

void print(int i) { ... }
void print(float f) { ... }

Its giving me this error for print(1.2);:

error: call of overloaded 'print(double)' is ambiguous 

Can anyone explain me why?

Answer 1

1.2 is a double literal not a float.

So the compiler requires an explicit disambiguation.

1.2f would work as that is a float literal.
