C or C++

Hi guys does default value for function prototypes are available in C.
int func(int i=5);

always give me a error saying there must be ';' ',' or ')' before '='

 

I don't believe C has that feature. You could probably use a struct as a hack but you'd still need to pass one in as an argument.

Code:

typedef struct
{
    int def_val;
} foo;

void bar(foo *t)
{
    // do something with t->def_val
}

int main(void)
{
    foo test = { 5 };
    bar(&test);
    ...
}

There's some complicated stuff over at stackoverflow if you're interested in giving that a try.
