Default Arguments in C

Code:

#include <stdio.h>


void func(int a, int b=2)
{
    printf("%d",a+b);
}


int main()
{
    func(1,1);
    func(1);
    return 0;
}

This code doesn't work in C. Is there a way to have variable b take a default value of 2 in C?
Thanks!

No. Default arguments and function overloading are both specific to C++. There is no equivalent in C.
