abort, terminate or exit?
...and on_exit functions.
std::terminate is what is automatically called in a C++ program when there is an unhandled exception. This is essentially the C++ equivalent to abort, assuming that you are reporting all your exceptional errors by means of throwing exceptions. This calls a handler that is set ...
const char* concatenation

The C way:
char buf[100];
strcpy(buf, one);
strcat(buf, two);
The C++ way:
std::string buf(one);
buf.append(two);
The compile-time way:
#define one "hello "
#define two "world"
#define concat(first, second) first second
const char* buf = concat(one, two);

In C++, this could lead to interesting complication, but this is out of topic (no C++ tag), so I won't elaborate.
then how to declare that structure as extern in both the files. ?
I fail to see the point, perhaps, but Greg Hewgi...
When to use std::size_t?
...be able to express the maximum size of any object (including any array) in C++. By extension it is also guaranteed to be big enough for any array index so it is a natural type for a loop by index over an array.
If you are just counting up to a number then it may be more natural to use either the ty...
