In that case the result case is showing null

#ot well, that's another issue, it's not C++ question, let's go to OT chat

Ok But I m doing it in c++ crud operation

The invite link shows expired

Any other link for ot

talk to my boy Klimi

you are talking here... why have you pmed me that you cannot talk?

photos are not allowed in this group

bruhhhh

but you can ask your doubts here

anyone help?

anyone help?

looks like you got some C++ source code. that will be $10

anyone help?

with?

?

$10?

You need to copy the array

you will need to make a full copy of the data structure

Since arrays just are pointers

how to link the L11 and L2?

Space complexity?

L1 TO L2

indeed, you cannot store more information without increasing the space complexity

oh, I see. You could use a data structure that only stores mutations to the array

I forgot what those are called though

the question is L1, L2, L1, L2, L1 ,L2

But they're popular in functional programming

something like that

why I cant send the picture?

Pictures are scary

i worder, do you have the latest telegram?

i cant send picture on this group

your reply are more scary

that's correct

Hello guys

Hello guys

what do you need dear Yazan

I have physics exam

Is anyone interested in helping me please

I have physics exam

But you choose to write C++ instead? Very relatable

Is anyone interested in helping me please

That would be cheating wouldn't it?

That would be cheating wouldn't it?

No it's helping

No it's helping

bro

No it's helping

so its not an exam/homework/assigment/task that you are graded / is required by your institution?

It is exam

But I will need help in it

It is exam

why don't you ask you professor for help?

i am sure he will help you out

Is anyone interested in helping me please

Cheater, shame.

they are 13631 members here, seem like nobody here

It looks normal to me.

Hi I'm full stack developer junior student. I'm working on project where I do vary controlls on C. If there is someone can tell me how to control the input of string from the user ,the string must only contains big or small letter. Better if we use procedures or functions. Thanks in advance

do you want someone to do your homework for you?

Just a general topic can we get raw data from a graph plotted on a website which is interactive type If possible can some one guide me plzz

#include <stdio.h> #include <stdlib.h> int main() { int i=2,d=2; while(d<100) { if(i<=d) { if(d%i==0&&i==d) { printf("%d",d); i=2; d++; continue; } if(d%i!=0) { i++; continue;} else break; } } } Is above code correct for printing prime nos under 100

do you want someone to do your homework for you?

Actually no I have done a good part and I'm blocked somewhere.

What I'm working on it is a big project. Let I explain the problems I get. I have an structure Typedef struct { Char name [DIM+1]; // dim is a macro }Example; Typedef struct { Example *example Int nElements }DynamicArray; You ask the user to enter his name, he\she can only input letters if the user puts show warning message and make to enter his\her name . Use Functions or procedures.

I have used strcmp In for loop inside for loop I used if statement. And isn't working.

it's hard to tell what's wrong without seeing the code. After you read the string you can go over it and make sure every character is a letter. I don't think strcmp can really help you here.

#include <stdio.h> int main() { int inputValue = -1; if (!((inputValue == 0) || (inputValue == 1))) { printf("Error "); } return 0; } How to #optimize this code ? 😢

hellooo everyone, ı use uart interrupt, I get data of 7 bytes every 200ms. I want to assign this data to the array. but it doesn't work good.

#ot

if (uart1_receive_flag) { uart_gelen[array]=uart1_receive_data; array++; uart1_receive_flag = 0; if(uart_gelen[2]==0x83){ P04=~P04; } if (sira>=8){ sira=0; }} }}

is there any problem at here

This can be simplified (not actually optimized, since the compiler will still optimize this for you). There's Boolean algebra that you probably learned or will learn in university that can help to understand how to simplify such expressions. Here's a cheat sheet: http://sandbox.mc.edu/~bennet/cs110/boolalg/rules.html Your expression in this math form is !(A + B) which by DeMorgan's law converts to !A * !B so the expression becomes if (inputValue != 0 && inputValue != 1)

I haven't checked it, so I can be not right, you can check it easily by building a truth table https://en.m.wikipedia.org/wiki/Truth_table

Basically there are 4 possible variants (3 actually), for each of them for the original and simplified code the results should be the same

Can someone tell me how to take inputs in a string and then extract integers from that string in c++ please guide me For example : I want the user to imter values as -> 1,2,3,4,5 and then extract 1 2 3 4 and 5 from it

try using split function

It would be better if you post your problem in a clearer wave

Einstein for example I want to take the input of Matrix elements from user but not one by one.... I want the user to enter the elements separated by a comma(,) Instead of entering like 1 2 3 4 5 6 I want him to enter 1,2,3,4,5,6 And then place those values in the matrix as 1 2 3 4 5 6

instead of commas let the user enter with spaces

Thanks Alot😊

Anyone can give a c program to add two numbers without arguments and return types

#include<stdio.h> #include<math.h> int main() { float a,b,c,root1,root2,rootpart,denominator; printf("enter the value of a,b,c\n"); scanf("%f,%f,%f",&a,&b,&c); rootpart=sqrt(b*b -4*a*c); denominator=2*a; root1=(-b + rootpart)/denominator; root1=(-b - rootpart)/denominator; printf("ROOT1=%f ROOT2=%f",&root1,root2); } output is wrong for root of no.
