function overloading in C

Apologies if this is a dup but if it is, I can't find it.

In C, can you define multiple functions with the same function name, but with different parameters? I come from a C# background. In C#, the following code is completely legal.

//Our first function

int MyFunction() {     //Code here     return i; }  int MyFunction(int passAParameter) {     // Code using passAParameter     return i; } 

In my specific case, I would like to create a function that has one optional parameter (that is an int) at the end of the parameter list. Can this be done?

Answer 1

No. C does not support overloading.

Answer 2

No. In strict C, you cannot do overloading.

However, given that most C compilers also support C++, and C++ does support overloading, there's a good chance you can do overloading if you're using a mainstream C/C++ compiler.

But its not strictly standard or portable to pure-C environments.
