#include<stdio.h> #include<conio.h>   int main() {    char password[128], c;    int index = 0;        printf("Enter Password : ");    /* 13 is ASCII value of Enter key */    while((c = getch()) != 13){        if(index < 0)            index = 0;        /* 8 is ASCII value of BACKSPACE character */        if(c == 8){            putch('\b');            putch(NULL);            putch('\b');            index--;        continue;        }        password[index++] = c;        putch('*');    }    password[index] = '\0';       printf("\nMy Password is = %s", password);        return 0; }
