C program to create login id & pwd and authenticate it.

/* This program is to illustrate how user authentication is made before allowing the user to access the secured resources. It asks for the user name and then the password. The password that you enter will not be displayed, instead that character is replaced by '*'         */

#include <stdio.h>
#include <conio.h>

void main()
{
char pasword[10],usrname[10], ch;
int i;

clrscr();

printf("Enter User name: ");
gets(usrname);
printf("Enter the password <any 8 characters>: ");

for(i=0;i<8;i++)
{
ch = getch();
pasword[i] = ch;
ch = '*' ;
printf("%c",ch);
}

pasword[i] = '\0';

/*If you want to know what you have entered as password, you can print it*/
printf("\nYour password is :");

for(i=0;i<8;i++)
{
          printf("%c",pasword[i]);
}
}

/*-----------------------------------------------
Output
Enter User name: Latha
Enter the password <any 8 characters>: ********
Your password is :Wipro123
