Sorry i don't know about k&r c
as i said it is the very very old & ancient version of c that is being forgotten but i think we should remember its significance

C does not require prototype of function is called. You get compilation warning

it just push the arguments to call stack and then call the function anyway

it's still the same in modern C

in fact that is why when writing function declarations that take no arguments, you should write (void) instead of ()
Anonymous
because () will let the function execute with any arguments

while (isOn == true);
{
std::cout << "1" << std::endl;
isOn = false;
for (int i=0; i<num; i++)
{
if (s[i].x==a.x && s[i].y==a.y)
{
mela();
std::cout << "2" << std::endl;
isOn = true;
}
}
}
Hi, when the program arrives at mela(), it freezes. Anyone know what the problem might be?
Samuele
void mela()
{
a.x=rand()%dim;
a.y=rand()%dim;
}
Samuele
a is a struct

Can anyone help me with this function.
int * compact (int * s1, int dim): receives an S1 vector filled with dim elements, and creates another allocated one
dynamically so that identical consecutive elements are replaced by a single occurrence. The function
it must return the pointer to a new dynamically allocated integer vector. For example, if S1 =
{1,2,2,4,4,4,5,6,7,7}, the function creates a new vector S2 = {1,2,4,5,6,7} composed of 6 elements.

are any of you guys into competitive programming?
Anunay
Organized two events in the past year
Marián
lol cool
Marián
i wanted to ask, what is any good resource to start?
Marián
i found myself being very but very bad in competitive progamming, like i can't do anything under pressure if it involves hardcore logical thinking and i want to improve it
Marián
codeforces
Anunay
i wanted to ask, what is any good resource to start?
Practice data structures and some commonly used algos
Marián
i know lot about datastructs but i am so back at algorithms, especially mathematical based
Marián
i know lot about CGI so i am into hardcore maths like calculus, linear algebra and stuff but when u ask me to do algorithm that finds some common prime factors blahl blah blah i am totally lost ngl
Anunay
Marián
is something like geeks4geeks good place?
Marián
hmmhhh okay
Anunay
will check this as well, thanks

Hi guys. Why this code doesn't work std::cout.print("hi").print(std::endl);
I am watching a playlist, that guy wrote and it works, but in my side it doesn't
☬ੴ Bassi
std::cout « "hi" « std::endl;
Marián
hmm interesting point of view
Marián
i always thought it's more about algorithms
Alion🦁
std::cout « "hi" « std::endl;
It is clear. But, why this doesn't work? where, he wrote and it was fine

Hi guys. Why this code doesn't work std::cout.print("hi").print(std::endl);
I am watching a playlist, that guy wrote and it works, but in my side it doesn't
#include <cstdio>

return 0;

yeah i just don't have time to anwer, i am in bus, will answer more in few hours, sry and thanks
Alion🦁
#include <cstdio>
int main() {
printf("hi");
return 0;
}
it is C code 🤦, I mean in c++
Alion🦁
Yeah, I was a bit surprised when I saw it too, but what can we do.
Alion🦁
#include <cstdio>
int main() {
printf("hi");
return 0;
}
btw, thanks for attention 🌹
☬ੴ Bassi
#include<iostream>
int main() {
std::cout « "hi" « std::endl;
return 0;
}
☬ੴ Bassi
maybe the guy made a print function prior
☬ੴ Bassi
thats why he is wrapping it in ()
Alion🦁
yes, from where did he "created" it IDK 😅

no you can write
std::cout.operator<<("hi").operator<<(std::endl);
Anonymous
i think he wanted to write to cout with that
☬ੴ Bassi
std::cout << print("hi") << print(std::endl);
☬ੴ Bassi
this might be possible
☬ੴ Bassi
maybe the guy is writting in another langauge like cython or something
☬ੴ Bassi
i have not seen cython code before

dude in the video he is telling you what this is doing

Even, I think, I will go and contact with him

he is explaining it assuming you have done some other language where there is no operator overloading

at 3:25 he removes the text

he is saying in other languages what we would do is this do this...
