Your testing against God without quotes, and without quotes the compiler thinks its another variable.

use "God" on line 14

I did that, then i get this: ISO C++ forbids comparison between pointer and integer

correct because you declared name as an int, it should be either a string or array of chars.

#include <iostream>
#include <string>
using namespace std;

int main()
{
	string name;
	cout << "Type your name here: ";
	cin >> name;

	if (name == "God")
		cout << "Hey God" << endl;
	else
		cout << "You're lying" << endl;

	return 0;

How would it be done with an array of chars?

#include <iostream>
using namespace std;

int main()
{
	char name[50];
	cout << "Type your name here: ";
	cin >> name;

	if (strcmp(name,"God")==0)
		cout << "Hey God" << endl;
	else
		cout << "You're lying" << endl;

	return 0;
}

So this might be the dumbest question you've ever heard. Im very new to C++ and i was wondering; is C++ programs only executed in cmd? If not, how can you change it?
Codermik (835)

No not dumb at all.

There is no limit to what you can do with C++. For example, the Windows operating system is written in it, most Windows applications are written in it, and most commercial games are written in it.

The cmd (or console I presume you mean) is ideal for learning the C/C++ language and once you are comfortable with C++ you then move on to learning Windows programming (assuming your on Windows) using the various API/Frameworks around.

If you are a beginner then I wouldn't suggest trying Windows programming just yet.

God should be a string which is have to be inside of double quote
