ok, I am wrong. I thought strtok does not modifiy string. you can`t put strtok before if because it can return NULL pointer

Is msvc actually up to date there?
There is a newer version that was released on November 10 with Visual Studio 2019 16.8 ( like 2 days ago) that it isn't there. But compiler that was released with 16.7 is.

How to print every word of a string individually
like the first word when we want
similarly the second word when we want
Google "How to print every word of a string individually in + (language)" I'm pretty sure there's atleast a website which has the code and explains how it's done.

Hello, can anyone tell me why this loop does not terminate no matter what I enter?

#include <iostream>
using namespace std;
int main()
{
char ch;
while (cin)
{
cin >> ch;
}
return 0;
}

#include <iostream>
using namespace std;
int main()
{
char ch;
while (cin)
{
cin >> ch;
}
return 0;
}
The while condition should become false for the code to end , ...

Ok thank

Putting a not operator before the cin causes the program to terminate without input. Please why?

Figured what is needed. Got to use a nested selection loop to decide when the program should terminate in the case where the expression for the while statement is just cin.

#include <iostream>
using namespace std;
int main()
{
char ch;
while (cin)
{
cin >> ch;
if (ch == '.')
return 0;
}
return 0;

Just realized that break statement would be most appropriate for the if selection as the return forces the program to terminate within the while loop hence external statements ignored.

Did you get why this happened?

Well, probably because the evaluation of !cin is false as the condition suggests that the action statements not being of the input stream variable cin. If I use cout as the while statement, everything works just fine.

You are given an array A, consisting of n positive integers a1,a2,…,an, and an array B, consisting of m positive integers b1,b2,…,bm
.
Choose some element a
of A and some element b of B such that a+b doesn't belong to A and doesn't belong to B
.
For example, if A=[2,1,7]
and B=[1,3,4], we can choose 1 from A and 4 from B, as number 5=1+4 doesn't belong to A and doesn't belong to B. However, we can't choose 2 from A and 1 from B, as 3=2+1 belongs to B
.
It can be shown that such a pair exists. If there are multiple answers, print any.
Choose and print any such two numbers.
Input
The first line contains one integer n
(1≤n≤100) — the number of elements of A
.
The second line contains n
integers a1,a2,…,an (1≤ai≤200) — the elements of A
.
The third line contains one integer m
(1≤m≤100) — the number of elements of B
.
The fourth line contains m
different integers b1,b2,…,bm (1≤bi≤200) — the elements of B
.
It can be shown that the answer always exists.
Output
Output two numbers a
and b such that a belongs to A, b belongs to B, but a+b doesn't belong to nor A neither B
.
If there are multiple answers, print any.

You should Use pastebin or alternatives to post the code.

Instead of posting full code here, you should paste it to pastebin / privatebin and share the link here.
Google pastebin, if you still don't understand

Hello guys, just a question about advanced programming.
I would like to create a class made up by a vector of threads, this class has to be a method that allow me to launch a new thread by specifing a function to e executed like argumeent
Luca
so how to pass a function like parameter to another function?
Fox
Use pastebin for your code, then share the link

The easiest and the most generic way IMHO is using std::function https://en.cppreference.com/w/cpp/utility/functional/function

Overloaded method is the same as creating any other method.

Is there a way to get sane warnings and errors in c++?
Talula
Not 184 lines of std templates and only show where the actual error is
I know it's confusing for many people that C doesn't show where the error actually is, shows something else but it's due to how original C was designed, it wasn't designed with \n in mind it was designed with ; to terminate the line.
Talula

So based on the old compiler ideas the C that is what all the compilers are following, C++ Builder has a better at displaying errors but it sucks in library, it's not free and it doesn't support half the things in life...

Errors are much better now with modern compilers, type traits and newly added concepts.
