Yes,
the purpose of captcha is to differentiate between Human traffic and bots.
One will require no time to code a bot which can read text captcha.
on the other side it will require too much image processing, computing and a smart algorithm to decode the text in image.
so it is difficult to crack.

is it easier to get hacked when you generate your own captcha code than when you use image captcha?
and how can I add alphabet to this code. this is the captcha that is created on your own.
<script type="text/javascript">
//Generates the captcha function
var a = Math.ceil(Math.random() * 99)+ '';
var b = Math.ceil(Math.random() * 99)+ '';
var c = Math.ceil(Math.random() * 99)+ '';
var d = Math.ceil(Math.random() * 99)+ '';
var e = Math.ceil(Math.random() * 99)+ '';
var code = a + b + c + d + e;
document.getElementById("txtCaptcha").value = code;
document.getElementById("txtCaptchaDiv").innerHTML = code;
</script>
