macOS Pointer and Cin Problem

[bobber205]

Below is what I use in Visual studio. Using getline I can have names entered that have spaces etc. If there is a space and I use cin, I get an infinite loop. (other code doesn't matter, it's just a function call.

All variables have been declared ok. What do I use insteasd of clear buffer etc on OS X?

void GetString(char* str) {

    cout << "Please Enter a String: " << endl;
    cin >> str;
   // cin.ignore(cin.rdbuf()->in_avail());
    //cin.getline(str, 100);
   // cin.clear();
    //cin.ignore(cin.rdbuf ()->in_avail());

    cout << endl;

}

Not sure I understand exactly, but getline works fine for reading spaces:

void GetString(char* str)
{
	cout << "Please Enter a String: " << endl;
	cin.getline(str, 100);
	cout << endl;
}

But when I try to run that function, it skips completely over my whole function call. The line "Enter your string" is printed, but I am never prompted to enter anything. It skips right along to printing the menu again.

Try clearing the input buffer before you "cout".

Hmmm... If I remember correctly the input needs to be put to a variable.

Just using cin or it's subfunctions doesn't do anything because it has nowhere to put it. Or at least that's what I'm getting from the code.

Try:

std::cin.ignore(std::numeric_limits<std::streamsize>::max(), '\n');
