Optimization to password.c

So, after a long time, atleast one of my friends came up with a couple of optimizations and an error for me to correct. The first error is that in the code at the end of the do-while statement, the comparison of counter to a number is not at all clear, so, here is what it should look like

while(counter<500); ----> this is to limit the number of characters in the string.

One of them is rather trivial. The initialization of the variable counter is not necessary as it is a global variable and will automatically be initialized to '0' at runtime.

A couple of good optimizations suggested by Barjatiya were as follows:
1. Instead of "goto end:", he says, I could have used a break. But I insisted that I like goto, and so he left me alone.

2. The other was instead of printing all the characters using a printf, I could rather converts the character array to a string and then print the whole thing. One problem was encountered that way, which again, thanks to baddu, I was able to correct it.


Note: Because of the html tags "<" and ">" , printing the code is a headache, and hence comparisons, and #include ...... will not work, If you copy paste the code. (Still trying to figure out someway.)

Second program, will be coming very soon. Keep checking.
Adios!

So, was wondering how a password field could be written in a compact way. The following source code in C, is just one of the many ways to do it.
Read through, and suggest optimizations if you can think of any.

The code:

//START.

#include "stdio.h"

#include "ctype.h"

#include "conio.h"

int counter;

char str[500];

void removelast(int);

int main(void){

  char c;

  int i;

   do{

    c = getch();

    i = (int)c;

    if(i == 13)

      goto end;

    else if(i == 8 && counter > 0){

      removelast(counter);

      putchar(0x08);

      putchar(0x20);

      putchar(0x08);

    }

    if(isprint(c)){

      printf("*");

      str[++counter] = c;

    }

  } while(counter <>

 end:

  printf("\nThe entered string is ");

  for(i=1;i<=counter;i++)

    printf("%c",str[i]);

  return 0;

}

void removelast(int a){

  str[a] = NULL;

  counter--;

}

//END.

 The above source code is allowed to be copied, transmitted,stored, and used in any way the reader sees fit. I just want people to appreciate what and how a small and beautifully written code can do wonders.

A is A.

Well, this is officially my first post now. After seemingly long unnecessary time spent in chosing what template to use and what font and all that, here I am finally scribbling my first thoughts after creating one. Any way, just want to say to all the readers out there, that from now on, I will be posting my daily doings here, just for me to remember them, and to share them with my friends. The daily postings may include some noobish C/Java code that I so passionately write to pass my time. For the time being atleast, this is what I enjoy doing!

Ok, now... next post tomorrow. Adios!
