#define usage in C/C++

Question

I need to write such a define in C/C++

#define scanf( fscanf(inf,

in order to replace each scanf( with fscanf(inf, literary

But I do not know how...

Thanks

You want to use a Variadic macro.

In your case, I believe you want:

#define scanf(...) fscanf(inf,__VA_ARGS__)
