I've never had any weird problems getting my submitted code to be compiled, but all the sudden I can't figure out what's going on.

My C++ program begins:

1 #include <iterator>
2 #include <ctype.h>
3 #include <iostream>
4 #include <vector>
5 #include <algorithm>
6
7 using namespace std;
8
9 string to_caps(const string s) {
10 string out;
11 for (int i = 0; i < s.size(); ++i) {
12 out += toupper(s);
13 }
14 return out;
15 }

and so on. (I didn't include line numbers in my submitted code; they're added here for your convenience.) I'm then told my code won't compile, and returned the following error messages:

Here are the compiler error messages:

04576192_24.c:9: syntax error before `('
04576192_24.c:11: `s' was not declared in this scope
04576192_24.c:11: parse error before `;'
04576192_24.c:20: parse error before `{'
04576192_24.c:24: syntax error before `='
04576192_24.c:26: `s1' was not declared in this scope
04576192_24.c:26: `s1' was not declared in this scope

and so on. This compiles just fine on my computer here, using "powerpc-apple-darwin8-g++-4.0.0 (GCC) 4.0.0 20041026 (Apple Computer, Inc. build 4061)". I've tried submitting both by uploading the file on the submit-o-matic and also by cutting and pasting the code there -- it doesn't make any difference. Can anybody figure this one out?

Try to add '#include <string>' to your program.

Yeah, that fixed it! (Feeling pretty dumb, though!) Any idea why it would still compile on my machine though?

maybe your compiler added string header file automatically...or it was included by another header file.
