Subject: [OT]: Circuit Cellar c souce code error challenge

Circuit Cellar have a code challenge that asks contestants to determine the
error in the code below.




I get ...

Line 5. Declares a variable that is never used (not sure if that is an erro=
r
per se)
	NOPE: Not an error

Line 8. Should be i++ not ++I
	NOPE: both i++ and ++i work

Line 9. '%s' not sure what effect the single quotes have but they look wron=
g
	NOPE: single quotes inside double quotes are just ordinary
characters

Line 9. *argv[i] should be argv[i]
	YEP! *argv[i] is a char, but %s expects a null-terminated string
like argv[i]

Line 10.1. perhaps a "return" in the function main since it is declared as
int.
	NOPE: good idea, but not strictly required



1. #include <stdio.h>
2.
3. int main (int argc, char *argv[])
4. {=20
5.  char ch;=20
6.  int i;=20
7.
8.  for (i =3D 0; i < argc; ++i) {
9.    printf ("Argument #%d: '%s'\n", i, *argv[i]);
10.  }
11. }
