Why does character input display a complete string if a string is entered?

[sindhu05]

Here's a simple code

 #include <iostream>
using namespace std;

int main()
{
	char c; 
	cin >> c;
	cout << c; 
	
	return 0;
}

If I enter, "HHH" in this.. It will display "HHH" as well. Why?
Shouldn't a character be reading a single character at a time?

Also, how do I check if the user has entered a single character or more than one character in a character variable (without using string variable)

You have a funny compiler!

It output just
H
for me.

I am using Visual Studio 2019.

Like I said. You have a funny compiler.

I used VS 2019 and I get only one character for the output from your source code. Same as lastchance.

Your copy of VS 2019 might be buggy, in need of repair.

If you enter HHH it will display

HHH
H

as expected. The first HHH line is what is echoed when input. The H line is what is displayed by the cout.
