Yeah, it's fine, kinda complicated, but fine

Welcome, read the rules :)

U have too many rules

Can you declare any variable of size one bit in C?

Guys is there some way to make not blocking input in C++? I'll try to explain you what I will like to do: user has 5 seconds to insert an input from keyboard, if he/she insert input in time, inserted value is printed on console, if times expire than program end.

if (0) to not execute this instruction with this flag -Wextra compiler checks for unused parameter. usually in such case (void*) cp_thread is used or compiler attribute

So many mistakes and I had time 😂

#include <stdio.h> float calc(float x,float y); int main (void) { float x, y, k; printf ("Type in 1st integer : \t"); scanf ("%f", &x); printf ("Type in 2nd integer : \t"); scanf ("%f", &y); k; k=calc(x,y); printf("After the calculation the k is %.3f\n",k); } float calc(float x, float y) { float m; m=(x+y)/3; return(m); }

I am facing a time related issue in hackerearth... beside using that snippet provided by oli

This problem does not seem to be IO bound so the small snippet should not have any impact on the outcome. Your algorithm is too slow. In general, inserting an element at the front of a vector is requires O(n) time, increasing the time complexity of your algorithm to O(n^2) - which is usually not suitable for n > 1000 (at least in coding challenges)

I have to learn that time complexity stuff... But can you please give me a hint that how can I reduce time

Do you actually need to copy all the elements into another vector? Can you do it by just "reading" from the input?

The question say that I have to shift the last element to the first k times, the best I can think is through vectors

yes, but it only asks you to print it (it doesn't care about the order in the vector)

I don't know how to do that... A hint please 🥺

Given the vector, do you know which element is the first one you should print?

If the input is 1 2 3 4 5, and k=2 then I have to print 4 5 1 2 3...

yes - so you should be able to "compute" the start index. Starting from that index you can print A[(StartIndex + i) % n] to get the elements in the expected order. This does not require additional memory and runs in linear time, which is ideal for this problem.

Hey guys i want to buy a book on c++, is bjarnes good? I m at entry level, know untill pointers very good. I will begin studing someclasses as well.. Will it be any good or is too much as a book? Can you give me AN advice? I don t care about The price i just want to learn more.

int main (void) It's actually saying void main?

no, when declaring a function C does not require you to list all the parameters the function expects. One can use void to explicitly tell the function does not take any argument.

Not to take returns?

Not to take returns?

parameters are independent of return values. This only applies to C and not to C++. Let's look at this example extern void foo(); But what parameters does foo take? you call it with foo(2, 3); or foo("aa");. Using a C compiler this compiles just fine - however your program might crash at runtime. extern void foo(); int main() { foo(23, 45); foo("asdsad"); } ——————————————- If you use the explicit void extern void foo(void)` the only way to call the function is by not passing any paramters int main() { // this is fine foo(); // "too many arguments" // foo(23, 45); // "too many arguments" // foo("asdsad"); } —————————————— Hence, when writing C, you should prefer to write foo(void) when your function does not take any arguments. For C++ this is implicit.

If all my fields are private, does my code totally satisfy encapsulation OOP criteria? Are there any other requirements?

Thankssss😍
