Thread: *sigh* Using Namespace Std; Woes

As suggested by Cat...

I'm working on a simple XOR program (with some file i/o). It uses some include files. Here they are:

Code:

#include <cstdlib>
#include <fstream>
#include <cstring>

using namespace std;

Now this does not compile. It throws errors at me, the same way as if I did not include <fstream> at all.

I am pretty sure that it is not my programs logic because when I used ".h" it worked perfectly. *sigh*, why must I trouble myself so much just to use "ANSI" standard. It works don't it?

I'll post some of the errors in a minute, Windows is freaking out on me. (As usual, Linux rules hehe)

Some of the error messages:

--'cout' : undeclared identifier
--'<<' : illegal, right operand has type 'char [51]'

Code:

while(1)
	  {
		  cout << "Are you sure you want to encrypt this file (y/n)? ";

--'nocreate' : is not a member of 'basic_ios<char,struct std::char_traits<char> >'
--'nocreate' : undeclared identifier

Code:

if(!(strcmp(argv[i],"--decrypt")))
		{
			fstream FileD(argv[1], ios::in | ios::out | ios::nocreate);

It was so much easier using the .h extensions.

first of all #include <iostream> that should fix your cout problem...according to my book ios::nocreate is not standard, but ios::in will not create and ios::in|ios:ut will not create anyway, so just remove ios::nocreate

But fstream has cout/cin. Your right, iostream did work. But...nevermind, it works right?

fstream only has ofstream and ifstream; iostream has cin/cout.
