Try Changing your taglibs:

<%@ taglib prefix="c" uri="htttp://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="fmt" uri="htttp://java.sun.com/jsp/jstl/fmt" %>

to

<%@ taglib prefix="c" uri="htttp://java.sun.com/jstl/core" %>
<%@ taglib prefix="fmt" uri="htttp://java.sun.com/jstl/fmt" %>

Yes, JSTL's out tag will transform certain characters to their XML escape sequences as stated in the documentation:

Attribute escapeXml: Determines whether characters <,>,&,'," in the resulting string should be converted to their corresponding character entity codes. Default value is true.

Note that if the goal is to produce cleaner markup then look at the escapeXml function in the http://java.sun.com/jsp/jstl/functions namespace as an alternative.

For just printing the out put both or same. But when we don't have value for variable 'a' then it will print 'NULL'.
To overcome this we can use default in c:out tag.

Ex:<c: out value='${a}' default='guest' />
