How to avoid pressing Enter with getchar() for reading a single character only?

Question

In the next code:

#include 

int main(void) {   
  int c;   
  while ((c=getchar())!= EOF)      
    putchar(c); 
  return 0;
}

Answer 1

yes you can do this on windows too, here's the code below, using the conio.h library

#include  //basic input/output
#include   //provides non standard getch() function
using namespace std;

int main()
{  
  cout << "Password: ";  
  string pass;
  while(true)
  {
             char ch = getch();    

             if(ch=='\r'){  //when a carriage return is found [enter] key
             cout << endl << "Your password is: " << pass <
