A novice programmer should in no way try to change the language that one is programming in. It will cause confusion and unjust practices.

I agree you should get used to using the code and not rely on the compiler. Some compilers require you to use more code for example in some programs that you write in Dev-C++ in some programs you need to include things like cin.get() and system ("PAUSE") they might be needed for some programs to work... They are just a few problems that I have come accrost (I dont know if I spelled that right lol) in my programming with Dev-C++

As a matter of fact, both the 1999 C standard and the C++ standard specify that falling off the end of main() [i.e. reaching the curly brace] is the same as returning zero. The ARM specified the same thing, so all C++ compilers (whether they predate the ISO C++ standard or not) should handle falling off the end of main() correctly. I'm not sure offhand, but suspect the 1989 C standard specifies the same thing.

There was definitely an issue with pre-standard C compilers: the behaviour on falling of the end of main() was unpredictable. So, if you have a C compiler that predates the 1989 C standard .....

Coming back to the original problem, proudnerd, linker errors usually mean that you haven't specified enough libraries on the command line. Or it might mean that some environment variables (which specify what directories the linker should look in for library files) ar not set correctly.

I'm sorry to bother you with my newbie-ness, but here's another code problem for you guys to help me with (and this time I'll include the errors

).

(Toggle Plain Text)

#include <iostream>
using namespace std;
int main()
{
	int favNumber;
	cout << "What's your favorite number? ";
	cin >> favNumber;
	if (favNumber == 13);
	{
		cout << "Hey, that's my favorite number, too!\n";
	}
	else;
	{
		cout << "That's not my favorite number, but oh well.\n";
	}
	return 0;
}

I get these two errors:

error: expected primary-expression before "else"
error: expected `;' before "else"

Try removing the ; after else.

also the one after if(favNumber == 13)

Thank you so much. It works perfectly now!
