Do i hv to learn basic of c++ to learn OOP

write a program with a function integral_sinus() which calculates integral with monte carlo methd

any one can help me?

Do i hv to learn basic of c++ to learn OOP

no

no

Then what should i do

Then what should i do

learn oop

#include <iostream> auto main() -> int { long i=0; int input=-1; for(;input!=0;) { std::cin >>input; i+=input; } std::cout << i; }

Ok thank

Can you just tell why you have used ptrfiif_t? and is it a pointer or array?

ptrdiff_t and size_t are good types for use as indices and sizes respectively. no problem with your unsigned int. https://en.cppreference.com/w/c/types/ptrdiff_t https://en.cppreference.com/w/c/types/size_t

thank you

Perfectly valid code tbh

Write a program that will get all the prime numbers that were written before that number in the input. The numbers displayed must be separated by a space.

Please see this code

if (cout == K) ^^

#include <iostream> int main() { unsigned N,K; std::cin >> N>> K; int i = 1; int count = 0; while ( i <= N){ int x; std::cin >> x; if( x>=123){ count ++; } if (count == K) std::cout <<"YES"; else std::cout << "NO"; } }

if (cout == K) ^^

Can anyone help me

Ok

Somebody will respond

Write a program that will get all the prime numbers that were written before that number in the input. The numbers displayed must be separated by a space.

I think the problem is something else

include <iostream> int main() { std::cout<<"5"; }

Purposely give a wrong answer to this one

Report back

Then let's test our algorithm itself, still keeping a wrong answer

#include <iostream> int main() { unsigned N,K; std::cin >> N>> K; int i = 1; int count = 0; while ( i <= N){ int x; std::cin >> x; if( x>=123){ count ++; } if (count == K) std::cout <<"YES"; else std::cout << "NO"; } }

if (x >= 123) decrease K. no need for count.

#include <iostream> auto main() -> int { long i=0; int input=-1; for(int j=0;j<6;++j) { i+=j+1; } std::cout << i; }

This should put out 20

Now why we are giving a wrong answer Gagik

Very simple

How can you tell that the data is supplied after the program runs?

Im just learning

It can be an example of writing the arguments on the program's cmdline

We send wrong answers to test our algorithm first

Then we insert a blank cin to see if cin is the blocker

It might be that you need to parse arguments instead of user input

Ok 1 minute

I only took 5 lessons.l dont know much.and its hard for me to talk like that.

I will send the task again if ir is easy.plase write the correct code

It is required to write a program that will receive N և K non-negative integers at the input, then a sequence of N elements. The program must output "YES" as a result if the correct K of N numbers are greater than or equal to 123 և ‘NO’ otherwise. It is forbidden to use mass.

#include <iostream> int main() { unsigned N,K; std::cin >> N>> K; int i = 1; int count = 0; while ( i <= N){ int x; std::cin >> x; if( x>=123){ count ++; } if (count == K) std::cout <<"YES"; else std::cout << "NO"; } }

Write a program that gets a natural number N at the input, then a sequence of whole N elements. As a result, the program must display the difference between the largest and smallest elements of the sequence. It is forbidden to use mass.

what first

what does this symbol և mean?

max and min?

i have no clue what this means

where i wrote it

where i wrote it

ok

its and

its and

oh

What's mass?

#include <iostream> int main() { std::ios::sync_with_stdio(false); std::cin.tie(nullptr); unsigned int N, k, temp; std::cin >> N >> k; while (N-- != 0) { std::cin >> temp; if (temp >= 123) { --k; } } if (k) { std::cout << "NO\n"; } else { std::cout << "YES\n"; } }

there is no real problem with your code

idk what you can do to minimise time

you need to take input obviously

Ah @chandradeepdey now I know who G is

Ah @chandradeepdey now I know who G is

lmao

Thanks

std::ios::sync_with_stdio(false); you should write that in any C++ code where you won't use C style I/O (printf, scanf, getchar, fgets, puts, etc.) std::cin.tie(nullptr); only for competitive programming. (there are other reasons such as manually controlling when to flush output) search on google for the meaning of those two lines

do them yourself lmao. just see if they accept this one. you can add those two lines in front to reduce execution time of your other programs

/get cbook

Maximum run time exceeded

Did you add std::cout << sum; at the end or just copypasted my code?

Did you add std::cout << sum; at the end or just copypasted my code?

Looks like latter 😆

you don't read N at the beginning, you should use it instead of 10 in the loop

the same as you read x... it feels to me that you have no idea of what you're doing with this code

Just want to ask. is there any estimation for when C++ modules will be production ready?

indices can be negative though

though you are right, if the array has more than ptrdiff_t elements, this will lead to undefined behaviour

any one is free

i need help

I found some #isempty function error in cpp code pls

ye edited now

hi

I found some #isempty function error in cpp code pls

need more details

#include <iostream> int main() { unsigned int a; std::cin >> a; int b; std::cin >> b; while(a<=b){ if (a%2==1) std::cout <<a<< " "; a++; } int i = 3; bool is_prime = true; while (i <= a/2) { if (a%i == 0) { is_prime = false; break; i+=2; } int g = 2; bool is_prime = true; while (g <= a/2) { if (a%g == 0) { is_prime = false; break; g+=1; } } } }
