> example i want search data where month 07 in my column table 01/07/2014 Looks like you need some query for the database: //MySQL syntax: SELECT * FROM table_name WHERE DATE_FORMAT(STR_TO_DATE(column_name, '%d/%m/%y'), '%m') = 'your_month_number' -- assuming that in your table 'table_name' you have a column 'column_name' -- which is …

I kinda like the idea behind the static/fixed header, but I was wondering if there's any chance to actually extend it, and add the user information to it, like this: 

Here this should fix it: for (double n = 1; n <= i; n++){ pi += pow(-1, n+1)*(4/(2*n-1)); } Pow requires double as arguments, so you'll need to make your variable from the loop a double. Another thing you could do, when you try to print real numbers, is to …

This is a simple string concatenation. In PHP, strings can be concatenated using the `.` (dot) operator (read more [here - Click Here](http://www.php.net/manual/en/language.operators.string.php) or [here](http://phphowto.blogspot.ro/2006/12/concatenate-strings.html)). In this case `$master_id` is a variable, so they used string concatenation to get its value and add it into the statement $master_id = "14"; …

You can also use the `stringstream` class - [Click Here](http://www.cplusplus.com/reference/sstream/stringstream/) Here's a small example: #include <sstream> #include <iostream> #include <string> using namespace std; int main(){ char a = 'a'; char b = 'b'; stringstream ss; ss<<a<<b; //adds both chars to the stringstream string concat = ss.str(); //you can get a …

Have a look at the `range(start, stop[, step])` function ([Click Here](http://docs.python.org/2/library/functions.html#range) ) from python. Also, you can use it to generate reverse lists: [Resource - click me](http://stackoverflow.com/a/14931024/1432385) Regarding your usage of the `map(function, iterable)` function: it applies a function to the iterable agrument, so you'll need some elements on which …

`WinMain@16` usually apears when you try to compile some files, which doesn't contain the `main()`/`WinMain()` function (starting point of the program). In your case, not including the souce file with the `main()` function in it was causing your troubles.

As of a quick search on Daniweb I got this: [Click Here](http://www.daniweb.com/software-development/cpp/threads/67312/connecting-c-to-ms-access) which contains other links to this: [Linking MS Acess to C++](http://reydacoco.blogspot.ro/2011/10/linking-to-ms-access-data-source-using.html) [Developing Access Solutions to native C/C++ from MSDN](http://msdn.microsoft.com/en-us/library/cc811599.aspx)

**NOTE:** this should be in the C++ forum thread. You need after each input operation to increase the size of the array. Your constructor definition is good, initializing the data, but you must have another function, let's call it `extendArray()` which increases your array size. For example: void extendArray(){ string …

Just logged in. This new layout... totally blew my eyes off. Will take some time to adjust, but I see you put a lot of effort in it. I hope others appreciate it. :)

Static arrays are allocated on the stack and they have fixed sized, e.g. their size cannot be changed, either shortened or expanded. Dynamic arrays are allocated on the heap. You set their size and than even change it, making them "dynamic". In order to use these kinds of arrays you'll …

I love how Dani was giggling almost all the interview. Immediately thought of this, I don't know why:

First of all, it's int main() not void main() 2nd, line 22 sum=sum+(rem*rem*rem); should be sum=sum+pow(rem, numberOfDigits); How to get that `numberOfDigits`? Easy, apply `log10` over it: #include <math.h> #include <stdio.h> int main(){ //don't forget this!!! //code goes here //get your range for int len = (int)log10(num)+1; //get the number …

What do you have so far?

1st, it's `int main()` and not `void main()` 2nd, You were actually doing a pointer aritmetic by this line: xx+= x + ", "; In your case, `", "` is a pointer to a sequence of characters. When you add an integer to that sequence, you are using pointer arithmetic. …

Still, you could've formatted the code a bit. **nullptr**'s example points out very well the use of a default constructor. For multiple elements to be initialized, you could go the plain old fashion way of: class Foo{ int a, b, c, d; float e, f, g, h; public: Foo() { …

Here's a small example. You can use the `getButton()` function from `MouseEvent`. final JLabel lblRightClickMe = new JLabel("Right click me"); //create a label lblRightClickMe.setBounds(152, 119, 94, 14); final JPopupMenu jpm = new JPopupMenu("Hello"); //create a JPopupMenu jpm.add("Right");jpm.add("Clicked");jpm.add("On"); //add some elements jpm.add("This");jpm.add("Label"); lblRightClickMe.setComponentPopupMenu(jpm); //set jpm as this label's popup menu lblRightClickMe.addMouseListener(new …

For a better understanding of this output, I suggest this code to run in the `main()` function: int main() { Base obj; cout<<" 1st - initialization.\n"; int b = obj+6; cout<<" 2nd - get the int via the int() conversion operator\n"; obj = b; cout<<" 3rd - create a new …

Your problem lies in line 17: name = ""; Your `name` attribute is initialized to a read only memory having `name` to point to that memory location, but any writing is illigal, thus your error. If you would initialize `name` as this: name = new char[200]; you would allocate memory …

What is the error that comes out of your pythonw.exe? Try runnning it in a cmd window to see if you have any errors.

As **iamthwee** pointed out, if you put in the constructor the name argument, that's ok, your object will set the name attribute to whatever you want, but, if along the run of your program, you want to make changes to your object, e.g. the course name has been changed, you …

Why would you need to `delete` p if it's not allocated by `new`? If you really want to "clear" out the `p` pointer, you could asign it to `NULL`.
