C plus plus program of periodic table?

The Periodic Table Of Elements has a well defined order. The layout can be emulated easily since the arrangement is quite logical.The first step would be to define a struct containing the following members as a minimum:- atomic number (int - number of protons in its nucleus)- symbol (char* - short form of the element name)- name (char* - long form of the element name)i.e.:struct elementinfo {int atomicnumber;char *symbol, *name;};Other members can be added as your program develops.The next step is to arrange the table itself. If you're using Win32 or another graphical system, it's a matter of drawing a box (Win32 would require a MoveToEx() call and four LineTo() calls) and TextOut() (or a related function) for the atomic number and element symbol (centered horizontally and aligned top and bottom respectively).Including conio.h or curses.h would give you the ability to position the cursor and even change the text color, allowing for an alternate "graphical" method.To keep things simple, storing the elements in an array would require something akin to the following:struct elementinfo elementlist[]={{1, "H", "Helium"}, {0, NULL, NULL}, {0, NULL, NULL},{0, NULL, NULL}, {0, NULL, NULL}, {0, NULL, NULL},{0, NULL, NULL}, {0, NULL, NULL}, {0, NULL, NULL},{0, NULL, NULL}, {0, NULL, NULL}, {0, NULL, NULL},{0, NULL, NULL}, {0, NULL, NULL}, {0, NULL, NULL},{0, NULL, NULL}, {0, NULL, NULL}, {2, "He", "Helium"},{-1, NULL, NULL},{3, "Li", "Lithium"}, {4, "Be", "Beryllium"}, {0, NULL, NULL},{0, NULL, NULL}, {0, NULL, NULL}, {0, NULL, NULL},{0, NULL, NULL}, {0, NULL, NULL}, {0, NULL, NULL},{0, NULL, NULL}, {0, NULL, NULL}, {0, NULL, NULL},{5, "B", "Boron"}, {6, "C", "Carbon"}, {7, "N", "Nitrogen"},{8, "O", "Oxygen"}, {9, "F", "Fluorine"}, {10, "Ne", "Neon"},{-1, NULL, NULL},...{-2, NULL, NULL}};In the above array, {0, NULL, NULL} represents a blank displayed for that particular cell, and {-1, NULL, NULL} represents a newline. The {-2, NULL, NULL} signifies the end of the table. The following for() loop would wrap around your display code like so:for (count=0; elementlist[count].atomicnumber!=-2; count++) {if elementlist[count].atomicnumber==-1) {// jump to next line of elements}else {// display current element}}Drawing this graphically, you'd have to keep track of the current cursor (X, Y) position.If you are sending this to stdout or another text stream (i.e. text file), you could draw each line, referencing the array of elements as you go. The list of elements would have to be stored in a nested array: the outermost array contains each line of elements in an array. This would do away with the {-1, NULL, NULL} terminating each line of elements.Extending this code to use classes would be relatively simple, but might only make sense if you were drawing this graphically storing each element as an object.The Lanthanides and Actinides, since they're displayed separately from the main table, would probably have to be stored separately for sake of convenience.Also, as laboratories continue to synthesize (or, on the rare chance, discover) new elements, the layout of the table may change (even drastically) to suit. Thus, the code would have to be altered accordingly.See the related links below for more ideas on how to design a program that displays the Periodic Table of Elements.(Note: Code originally posted was copyrighted.

Would I accept or reject the null hypothesis if the probability of the obtained statistic is 0.001 and alpha is 0.05?

You should reject the null hypothesis.

If null is compared with null what is the result-true or false or null or unknown?

You mean SQL? NULL = anything IS NULL NULL <> anything IS NULL ... NULL IS NULL = TRUE NULL IS NOT NULL = FALSE

How would you determine the expected frequencies for a chi-square goodness of fit test?

You first decide on a null hypothesis. Expected frequencies are calculated on the basis of the null hypothesis, that is, assuming that the null hypothesis is true.

How do you do a null?

You can't, there would be just too many results

Length of a null string is supposed to be 1?

A null has no length... I dont know java or c but in sql and vb there are functions to convert nulls isnull(some_field,' ') would return either the field, or a space if its null

Is null node equal to leaf node?

No. A leaf node is a node that has no child nodes. A null node is a node pointer that points to the null address (address zero). Since a leaf node has no children, its child nodes are null nodes.

How do you get to the null in supersecret?

There is no null, it is just what it says when you log out. There is a null.

A contract is null and void in the case where one part is in error as to the contract itself?

no, only that part is bad. if that were the case, the constitution would be null and void.

How much is new zealand's departure tax?

It depends on which airport you are leaving from. It can be null, as it is included in ticket price. or you can pay $NZ25/

How do you do a null search?

You can't, there would be just too many results

How do you pronounce NULL?

"NULL" is usually pronounced as "null" (rhymes with "mull").
