Re: Why do we get ambiguity errors in c++?

Hi,

There's a conversion of the data-types so, the compiler gets
confused because, you can pass an int to a function that takes a float.
Conversions performed behind the scenes makes=A0 this possible, but as we
see in the sum(...) functions this can also cause ambiguity when
overloading functions. Conversions between arrays and pointers can
cause the same type of problems.=20

The function call can be made using : sum(9,(float)9.0);

I hope this was helpful.

Thanks,
Jim Smith

=20=20=20=20
            Hi everyone can anyone tell me

if i give=20

int sum(int,int) ;

int sum(float,int) ;

int sum(float,float) ;

int sum(int,float) ;

prototypes in a pgm and give a call to sum(2,3.4);

Then an ambiguity error comes between sum(int,int) and sum(int,float) ;

WHY???
