Can we sort using a single loop?

where 'x' is the integer array name, 'n' is the number of elements in 'x'.
This for loop sorts the elements of the array in ascending order. To sort in descending order, change "if ( x[ i ] < x[ i + 1 ] )" to "if ( x[ i ] > x[ i + 1 ] )"

I have no way of testing all of these, but I'm pretty sure they'll work.

Problem reading a file

Hey Dom,

Your code works fine for me..
i get the output as that of the file.
your output is obtained only when there is a space in the file. You could check comparing the output with space.

Please try out with some other files to read...... and i feel its the error is with the file you read.

Benefits of Increment Operator

Agree.

Further (Adding to the explanation which i came across in my early days when i was learnin C++)

if we observe

i=i+1;--> 2 operations i.e, mathematical addition operation and then assignment operation.

i++ or ++i ----> only one operation i.e, increment

I guess these operators existed in C and C++ because some microprocessors have instructions for exactly these operations. A compiler has an easy job when it finds one of these operators in your source code, because it can then just convert the code to those machine language instructions directly. I think any modern C or C++ compiler nowadays would be smart enough to also optimize a statement like i = i + 1 to an efficient, single machine language instruction, but really old C compilers of the 1970's might not have such optimizations built-in.

This number of operations also effect the processing time, processing efficiency and also the complexity,
We would be more clear if we think the same in view of cpu processing.

This is also one of the reason but is not the only reason.. as there may be many other factors effecting the processing capabilities....

problems validation.xml in struts 2

Hey Manish,

After observing your files closely i found a mistake.....
Mostly that might cause the error

First remove all the error tags { sorry for that}
then check yout EmployeeLogin.jsp withe the validation.xml file

EmployeeLogin.jsp

</head> <body> <div id="global"> <h3 align="center">Employee Login</h3> <s:form action="Login" validate="true"> <table align="center"> <tr> <td><s:textfield name="userName" label="User Name" </td> </tr> <tr><td><s:password name="password" label="Password" /></td></tr> <tr><td><s:submit/></td> </tr> </table> </s:form> </div> </body> </html>

login-validation.xml

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE validators PUBLIC 'PUBLIC:-//OpenSymphony Group//XWork Validator 1.0.2//EN' "http://www.opensymphony.com/xwork/xwork-validator-1.0.2.dtd"> <validators> <field name="userNAME"> <field-validator type="required"> <message>User Name is required </message> </field-validator> </field> <field name="password"> <field-validator type="required"> <message>Password is required </message> </field-validator> </field> </validators>

The name in the login.jsp and the validator.xl must be the same ,,, here you user "userName" in login.jsp and "userNAME" in validator.xml they are different.........

Hope this helps

problems validation.xml in struts 2

Welcome to Ranch..

Please use code tags to post any kind of code

Now, about your question did you try to refer and use the error tags
<html:errors/>

in your case try to insert the tag <s:errors/> ---------- this tag is used to display all the error messages
if you need to display the error message for each and every property at different positions <s:errors property="propertyname"/>

Hope it helps
