Same function different parameter var types

Hello Cprogramming,

I've got some code which I want to run for floats and doubles. Now I can make two functions like this:

Code:

---

void some_func_f(float f) { /* code */ }
void some_func_d(double d) { /* same code */ }

---

but then I got duplication of code. Is there any nice way to get this done in C without duplication of code?

Floats will get automatically promoted to doubles, assuming you mean what you say about "same code", so just do the second one.

Nope, I want the function to use 'real' floats. :(

C does not permit function overloading... you need C++ for that.

However in this case, with it returning void, you can use the second one for both because a double can hold a float value easily enough. Although, if you were returning a double, you might have a problem assigning it to floats.

for that you need templates..which means C++

Not templates, overloading. But yes, C++, for now. If only you had a C1X compiler with Generic_ support...

why not templates? :O
templates is like a super function overloading..and as you can he even has different function types..
and that looks like templates to the rescue to me
anyways...welcome back CTater :D

Actually templates use overloading... but function overloading is a native part of C++ that can be used at any level of the language.
