overloaded function question

[manju23reddy]

consider overloaded functions
//function 1
void hi(int a)
{
}

//function 2
void hi(int a, int b = 20)
{
}

int main()
{
hi(10);
}

which function will it be invoked and y.

Please give your topics proper titles; 'hi' is not a proper subject title.
I have changed your other topic titles (all were named 'hi'). Don't do that anymore.

Well I would suggest you try compiling your example and see what it does. Just add some cout statements to you functions so you can see which one is called.

If you manage to get you code to compile without error then you can run it and find out which one is called then you can begin to attempt an explanation of why.

Correct :-) and that is your answer, the question which one will be called is pointless because the compiler will not compile it so neither will be called.

You have to make the function call unambiguous in this case either by removing the default parameter on the second overload or examining why there are 2 overloads and removing one of them.

i cant imagin why you would ever need to do something like this.
but you have your answer.
