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

if(argc < 2) { printf("Need File\n"); return -1; }

char * filename = argv[1];

return print_file(filename); }

int print_file(char * filename) { FILE *f; f = fopen(filename, "r");

if(f == NULL) return -1;

const int BUFFER_SIZE = 100; char buffer[BUFFER_SIZE];

while(fgets(buffer, BUFFER_SIZE,f) != 0 ) { printf("%s", buffer); }

fclose(f); return 0 ; }
