ok,

ifndef MY_HEADER_FILE
#define MY_HEADER_FILE

// ... Here goes the implementations

#endif // MY_HEADER_FILE

Well, I haven't seen the files but here is my guess. The most common reason while compilation of this error is that, you include a file in one file and include the same file in some file (there is no...

The two different implementations can acheive the same results, but they belong to two different familes. One is strucutural and you'll find the C implementations like that (although it does work in...

Take a look at http://cse.yeditepe.edu.tr/~osertel/courses/CSE211/materials/lect6.pdf,
You'll find the explaniations in it.

What compiler are you using? I had this problem way back, when I was in learning phase and used Turbo C++, and I had to stop it manually, in MS Visual C++ console applications, it is handled...

Yes, you can write all the 3 class definations in one header file and implementation in one source file (in fact, you can write everything in one file as well).


// Class delarations
class A
{...

One solution can be, before inserting the new no. in the array, scan the array (iterate through it), to see whether the no. is already in the array or not, if not, insert it and yes, loop again.

try this,

struct SData
{
char name[128];
int Values[3];
};

SData myData[3];

Take a look at this (http://www.codeguru.com/Cpp/data/data-misc/xml/article.php/c8287/)

Try this


int i, total[3];
int myValue[3][3];

myValue[0][0] = 53000;
myValue[0][1] = 5;
myValue[0][2] = 1;
