So you've posted your code and what now? What is your question?

What you mean is dynamic memory allocation, check out [URL="http://www.cplusplus.com/doc/tutorial/dynamic/"]this[/URL] first and feel free to ask questions if you don't understand something :)

Is "Press ENTER to continue" also good? [CODE] cout << "Press ENTER to continue ..." << endl; cin.get(); [/CODE]

[QUOTE=ulisse0;862149]What? I have no idea what you are talking about.[/QUOTE] He's talking about the C++ [ICODE]fstream[/ICODE] class(es) Edit:: Sorry I misunderstood the OP's post (he was actually quoting but I didn't notice that) :(

When a class has one or more pure virtual methods, the class is called an abstract class, but you cannot just create an object from it, you first have to derive a class from your abstract class and then you've to override the pure virtual methods before you can use …

->First: Please post using code tags! ->Second: You have to know how to write manipulators :)

Actually you should check the input on being a valid integer or not :) To check whether the input is an integer or not, you could do something like this (you'll have to pass the input as a string): [CODE=C++] bool checkInt(const string &s) { int len = s.length(); for(int …

Dev-C++ starts getting dated, use the newest MinGW-compiler(s) instead ... Edit:: Actually there comes a document with the distribution which describes the whole process ...

Put [CODE] cout<<endl<<"Wrong option number!!

Try again\n"; cin>>option; } while(option<1 || option>2); [/CODE]

You could change your get_char function to: [ICODE]char get_char(int n) {return n-'0';}[/ICODE] (edit:: unless your goal is to also provide conversions from other bases) In your rev-function (see line 72) a for-statement would be better to use I think, it will also compact your code a bit :) (You can …

[ICODE]while (count=0);[/ICODE] has to be [ICODE]while (count==0);[/ICODE] If you write [ICODE]while (count=0);[/ICODE] then variable count gets assigned value 0, so this means the assignment will return zero which is equal to false with the result the while loop won't run :) ...

Another remark: avoid the use of [ICODE]system("pause");[/ICODE] (See [URL="http://www.gidnetwork.com/b-61.html"]http://www.gidnetwork.com/b-61.html[/URL]) You could use [ICODE]cin.get();[/ICODE] instead of [ICODE]system("pause");[/ICODE] :)

The first question you should ask yourself is: is it worth all the work to built in all those code to create a demo version? What's your application about, what does it do? You should also think about the following problem: If the trial/demo period has ended, the user could …

To do conversions between numbers and strings, [stringstreams](http://www.java2s.com/Tutorial/Cpp/0240__File-Stream/Usestringstreamtoparseanumber.htm) are often used :) Lines 28-50 can be replaced by: `return a-'0';`

Dear rahul, your code won't compile: [ICODE]student std[x];[/ICODE] is never going to work :P (edit:: unless x is a constant expression) Thats just what the OP was asking for: Dynamic Memory allocation, your code doesn't explain dynamic memory allocation I think ...
