Here is my source code about converting the inputted password into asterisk * in C and C++

#include "iostream.h"
#include "conio.h"
#include "cstring.h"        // for strcmp

using namespace std;
int main(void)
{
  int c;
  int i;
  char pw[80];
  start:

 printf("\n1Enter Password:");

  for ( i = 0; i < 79 && (c = getch()) != '\r'; ++i ) {
    pw[i] = c;
    putch('*');
  }

  pw[i] = '\0';


  if ( strcmp(pw, "CORRECT") == 0 ) {
    printf("\nPASSWORD CORRECT");
  } else {
    goto start;
  }
  getch();

  return 0;
}
