Password Validation Using C: getch()

[Basavaraj]

#include<stdio.h>
void main()
{
  char pwd[20]="Oracle";  // your password.
  char ent_pwd[20];  // The typed password will be stored in this array.
  char ch; 
  int i=0;  // used refer array index. 
  printf("Enter the password : ");

 while( (ch=getch()) !='\r' )  // getch() is used to read the char soon after pressing the key.
 {
    ent_pwd[i++]=ch;
    printf("*");  // '*' is echoed for each keypress
 }
 ent_pwd[i]='\0';  // assign null char to string( user entered password ).

 if( strcmp(pwd,ent_pwd)==0 ) // if password matched
 printf("\nLogin success full");
 else
 printf("\nLogin failed");

 getch();  // here getch() is used to go to user screen.( general use of getch() )

}

Note : getch() is unformatted unbuffered character input function,unbuffered means the char typed will read readily without waiting for enter key to be pressed.
