Extremely simple program not compiling

[immortal192]

I get compiler errors about ambiguous overload for the following code and I'm not sure why.

#include <iostream>
using namespace std;

int main(){

	string input = "";

	do {
		cout << "Want to continue? y/n" << endl;
		cin >> input;
	} 
	while (input =! "n");
		
	return 0;
}

It's a simple program to continually ask user something until he enters "n", which will then terminate the program.

Much appreciated.
