How do I print a file name? I have the filename coming from the ls | ./sourcefile. Here is the code I have so far.

#include

#define OFFSET 16

int main (int argc, char const *argv[])

{

char buff[OFFSET] = "";

int read, address = 0, i;

FILE *fp = argc > 1 ?

fopen (argv[1], "r"): stdin;

if (!fp) {

//print file name

return 0;

}
