Hi guys what does this mean: 1<<14
You shift 1 by 14 to the left. The binary representation looks like
0000 0000 0000 0001 for now. For each left shift you move 1 a position to the left so in the end you have
0100 0000 0000 0000.
Each left shift doubles the value.

Hi guys what does this mean: 1<<14
it shifts the number "1" by so and so many positions in the bit representation

Thank you guys very much that makes sense

How to count length of word without string
Count code points (not chars) until you find a character that matches isspace

To separate and modularize code. You can have classes with the same name in different namespaces.

Where do we need to use Union, apart from memory saving apply?[real time application]
To reuse memory for different purposes (saving memory).
Some might answer to "map different data types", however this it neither defined by C nor by C++. I would advise against it.

But to answer that, Ajax is asynchronous network requests, usually used by webpages to get more data from a server

I am supposed to take about 6 to 10 students and introduce them to the core c++ and a guide frame work.. I have started with them.. but I'm wondering about the guide framework.. a simple and easy to pick

Otumian
Maxi, have you tried gtk

Because out of bounds memory access
Bingo, that's why u need multiple compilers and do some runtime analysis to prevent subtle bugs. Clang Segfaults, GCC doesn't prolly stop where dest ends OR just time bomb
C++17 to the rescue:
template <class T, class T2, int32_t N1, int32_t N2>
inline void copy_array(T(&src)[N1], T2(&dest)[N2])
{
if constexpr (N1 < N2) /// rhs > lhs
std::copy(std::begin(src), std::end(src), std::begin(dest));
else
std::copy(std::begin(src), std::begin(src) + N2, std::begin(dest));
}

std::min is constexpr since c++14

well , c++ isn't the best option for ( something simple )
why you would bother with cpp at all , pick js or python if you want something simple
and in general , afaik there are nothing like " simple framwork "
but what you can do is
you can simplify the concepts of a framwork you know

May I suggest that you pick a non graphical framework like PoCo ?
Ludovic 'Archivist'
I generally present that one since it allows to do web development and is /fairly/ simple to learn for beginners

does std::min have compile-time guarantees in C++14 ?

You're probably against the Qt moc? Anyway I find Qt to be the best choice in native GUI toolkits

C++ can generate some pretty amazing types with templates

yes, constexpr has been added in c++14
if constexpr is more clearer ofr my use case, and most use cases 'cos I need the value of std::min to assigned in @ least two different places... Seems like a work for if constexpr

so this might be really subjective.. I like the single line better, imo it's easier and faster to read, faster to write and code duplication is minimized
Depending on coding guidelines (e.g. not to omit optional {}) the if - else construct can become quite clumsy
