[avr-gcc-list] Cpp Question

[Matjaž Janežič]

Hi!

I was recently more involved in Pascal, now I'm in C :)

I'm trying to program a function which returns values as parameters:

void foo(int a, int b, float c)
{
b++;
c=sqrt(a+b)
}

but it does't work
In Pascal it could be done if it is written as

procedure foo(var a,b:integer;var c:real)
begin
b=b+1;
c=sqrt(a+b);
end;

and voila, you get after foo(a,b,c), b incremented and 
c as stated :)
but it won't work if the procedure is as that:

procedure foo(a,b:integer; c:real)
begin
b=b+1;
c=sqrt(a+b);
end;

soo after call to that with foo(a,b,c), original a b & c
won't change. how to do this in c?

Regard!
