# ./write_on_stdout A binary that writes on standard output the first given argument (the same behavior as `echo` but with only one argument). If no argument is given, it writes the string "write on stdout". ```c #include #include int main(int argc, char **argv) { if (argc == 2) { write(1, argv[1], strlen(argv[1])); write(1, "\n", 1); } else { write(1, "write on stdout\n", 16); } return (0); } ```
