Is it possible on Windows without using WinAPI?
You may not remove last character.
But you can get the similar effect by overwriting the last character. For that, you need to move the console cursor backwards by outputting a '\b' (backspace) character like shown below.
#include<iostream>
using namespace std;
int main()
{
cout<<"Hi";
cout<<'\b'; //Cursor moves 1 position backwards
cout<<" "; //Overwrites letter 'i' with space
}
So the output would be
H
