Should the program prevent input like: [ICODE]A3--5,9-01[/ICODE] ?? Is it allowed that the problemset's name contains more than 1 character ? What to do with things like: [ICODE]A35,9-01,A-Z-9[/ICODE] ??[B] >And then convert it back to char with itoa()[/B] itoa() is non-standard.

[B]>Any clue to the solution???[/B] Yes, start with the structure.

[U][B]Struct(ure):[/B][/U] In C++ you could say that a [B]struct[/B] is also a sort of class, but when someone uses the struct keyword, he's often just referring to a structure as ([B]POD[/B] = Plain Old Datatype), POD means that it's used as they did before in C: a structure is used …

That's because for each integer printed, all operations will be executed. For example, with me this would give the following output: [ICODE]4 5 4 5 4 5[/ICODE] The first integer printed, is the result of all the following operations, executed directly after each other: [B]i,i--,--i,i++,--i,i++[/B] Let's step through this: At …

[B]>"->" is used to access data members on the heap[/B] The arrow operator [B]->[/B] is used to access data members (of a class) via a pointer, these data members do not necessarily have to be on the heap, consider the following example: [CODE=cplusplus] // declaration of the 'counter' structure: struct …

[B]>Do you think this would cause memory problem?[/B] Well, that actually depends on how much RAM there's inside your computer, whether you're planning to create arrays of structures, etc. ... You can quickly check how much bytes a structure occupies in your computer's memory by using the [B]sizeof[/B] operator. You …

[B]>First make sure in your code every time you open a file you close it.[/B] Any [B]fstream[/B] (and thus also [B]ifstream[/B] / [B]ofstream[/B]) object has what's called a [B]destructor[/B], this destructor will close the file automatically when the file-object goes out-of-scope. So actually there's no need to explicitly close a …

And a little addition to niek_e 's post: To get the amount of bytes a[B] float[/B] and a [B]double[/B] occupy in memory (on your implementation), you can use the [B]sizeof[/B] operator: [CODE=cplusplus] cout << "Float: " << sizeof(float) << endl; cout << "Double: " << sizeof(double) << endl; [/CODE]
