One way is to read up about "Default Arguments in C++ Functions",
but that might not solve all your problems.

i dont know any special ways in C++, but varargs are one way to do (in
C) and i believe its portable too

 

[Son of Sam]

do u mean this:

int main(int argc, _TCHAR* argv[])
{
.....

or do u want to call a function like this:

int bum(int x, char g, string pop)
{
....
bumb(0, "", "only here")
or woot?

Don't, find a better way! This hangover from C looses all of the type
safety provided by C++

If the arguments have the same type, you could pass the arguments in
a vector or list or something of that sort. Otherwise, stick to Ian's
advice.

An another solution is a string. write all parameters to a string,
like "x=10,name=ashu,y=20.05" and parse this string inside the
function.

Surely a map of strings with your favourite key type would be more flexible, easier, faster, than that?
