Undefined behavior - don't do it!
7.21.5.2 2
If stream points to an output stream or an update stream in which the most recent operation was not input [...] otherwise, the behavior is undefined.

You will need a library for this
BinaryByter
gtk should suffice
BinaryByter
Or ncurses
BinaryByter
alternatively, you will have to do some interrupt trickery
BinaryByter
good luck!

Hello Everyone
Can anyone send me the code of
Printing (1 to 20) or (1 to n) number without using any type of loop in Java ?
S.
use recursion
Ankur
No...not using recursions and ol
Dima
S.
?? You just said it couldn't use loops
S.
recursion not included
Ankur
Okay my mistake...now I request also not to use any type of recursions
Liam
Okay my mistake...now I request also not to use any type of recursions
/warn
Off topic. This is a C/C++ group.
Ankur
Okay guys
Ankur
I leave 🤘
S.
😂 You'd just ask how to print (1 to n) without using loops or recursions in C/C++
Ankur
Yaa my mistake
Ankur
I didn't took it serious
Ankur
😜😜
Liam
use template in C++.
S.
That's magic
Liam
#include <iostream>
template <size_t N>
void counting(std::ostream& os) {
counting<N - 1>(os);
os << N << std::endl;
}
template <>
void counting<1lu>(std::ostream& os) {
os << 1lu << std::endl;
}
int main() {
const size_t N = 10;
counting<N>(std::cout);
return 0;
}
Liam
done.

Hey guys I'm not an admin
Ankur
Yaa
Ankur
Okay again my mistake😊
S.
#include <iostream>
template <size_t N>
void counting(std::ostream& os) {
counting<N - 1>(os);
os << N << std::endl;
}
template <>
void counting<1lu>(std::ostream& os) {
os << 1lu << std::endl;
}
int main() {
const size_t N = 10;
counting<N>(std::cout);
return 0;
}
Doesn't the template use recursion?
Ankur
Yup but I don't want the 3rd warn
Liam
'cause they are different functions.
S.
Oh... i see
Liam
256 for clang by default and 900 for gcc by default.
S.
OK. Thx for the info
Wolf
😊 pleasure all mine
S.
Seems C doesn't have a define magic counterpart 😆
Liam
If one doesn't want to use template meta-programming here, one could utlize static class member as a counter virable, and increase it in its constructor. In this case, create an array with given length will increase the static member. If you print it out in its constructor...
Liam
Something like this:
#include <iostream>
struct Counter {
static size_t count;
Counter() {
std::cout << ++count << std::endl;
}
};
size_t Counter::count = 0;
int main() {
Counter a[10];
return 0;
}
