Hello

cover everything?... i don't think that book exists... just pick one you like or look on stackoverflow if you need word from others

Thank you sir

🙏🙏

Good evening .... Has anyone bjarne stroustrup's C ++ Programming book in PDF format?

Read the rules.

They have a variable equal to 5. Another variable has been declared, b. How to code so that variable b gets the value from the above variable a.

Can you help me please.

b=a

If the total price is less than $ 50, vat = 0% (0.00) If the total price ranges from $ 50 to $ 800, vat = 10% (0.10) If the total price is more than $ 800, vat = 20% (0.20)

Write the above program code and display the amount, vat and total (total = amount * (1 + vat))

Thank you rose

Given an array of length N and an integer x, you need to find all the indexes where x is present in the input array. Save all the indexes in an array (in increasing order). Do this recursively. Indexing in the array starts from 0. #include <iostream> using namespace std; int checknum(int *arr, int* output, int size, int num = 2) { static int index = 0; static int j=0; if (index >= 0) { int val = arr[index]; if (val == num) { output[j]=index; j++; } else if(index==size){ return j; } else { index++; return checknum(arr, output,size); } } return -1; } int main() { int output[50],sizeofoutput; int arr[5] = {1, 2, 2, 3, 4}; sizeofoutput=checknum(arr, output, 5); for(int i=0;i<=sizeofoutput;i++){ cout<<output[i]; } return 0; } this is my code but got runtime error

Greetings guys I am new doing software engineering and I am using code blocks software to program any recommended textbook to best learn c/c++ language ?

#include<iostream> using namespace std; void dummy(int* arr){ } int main(){ int arr[5][5]; dummy(arr); }

#include<iostream> using namespace std; void dummy(int* arr){ } int main(){ int arr[5][5]; dummy(arr); }

Giving error.

But when passing 1d array it's working

can I ask win32 GUI development related questions here?

On Windows, there is this thing called “virtual list control/view”, we create the list control with LVS_OWNERDATA, then tell how many items we want it to show by sending LVM_SETITEMCOUNT message with desired number, say 1 million, the control handle the drawing and scrolling and notify parent asking for information (text, image, etc.) needed to draw a specific item. LVN_GETDISPINFO will then needs to be handled in user code for that https://docs.microsoft.com/en-us/windows/win32/controls/lvn-getdispinfo

#include<iostream> using namespace std; void dummy(int* arr){ } int main(){ int arr[5][5]; dummy(arr); }

void dummy(int arr[][5]) { } int main() { int arr[5][5]; dummy(arr); }

So I think we can in theory simulate a tree control based on a virtual list control by using the aforementioned mechanism and custom draw +- buttons and click event. The reason for doing this is that inserting millions of tree items into a tree control is slow. Now, my questions are: 1) How should the interface looks like? 2) How to quickly find the corresponding tree node by a given row index? Must also take into account of expand/collapse states of nodes.

void dummy(int arr[][5]) { } int main() { int arr[5][5]; dummy(arr); }

Can we use variable as column size?

if pass the array variables to function , array decay conversion apply to array. So only you can send pointer. In two dimensinoal array after first coulumn you can use.because it correspond to type of pointer.

Ok, thanks

Hi anyone with language C simplified short notes,kindly share I'll appreciate.

#include<bits/stdc++.h> using namespace std; int main() { int item[10],max,min; cout<<"Enter the value of items "; for(int i=0;i<10;i++) cin>>item[i]; max=item[0]; min=item[0]; for(int i = 0;i<10;i++) { if (max<item[i]) max = item[i]; if (min>item[i]) min= item[i]; cout<<"maximum is "<<max<<" minimum is "<<min; return 0; } }

i want to print the maximum and minimum value

what's wrong in this code ?

still it's not working

still it's not working

If (condition) {task}

Yes

#include<bits/stdc++.h> using namespace std; int main() { int item[10],max,min; cout<<"Enter the value of items "; for(int i=0;i<10;i++) cin>>item[i]; max=item[0]; min=item[0]; for(int i = 0;i<10;i++) { if (max<item[i]) { max = item[i]; } if (min>item[i]) { min= item[i]; } cout<<"maximum is "<<max<<" minimum is "<<min; } }

right ?

right ?

It runs now?

It runs now?

nope

wrong output

nope

Then I m a python programmer.. Sorry

ah it's okay 😁

#include<bits/stdc++.h> using namespace std; int main() { int item[10],max,min; cout<<"Enter the value of items "; for(int i=0;i<10;i++) cin>>item[i]; max=item[0]; min=item[0]; for(int i = 0;i<10;i++) { if (max<item[i]) { max = item[i]; } if (min>item[i]) { min= item[i]; } cout<<"maximum is "<<max<<" minimum is "<<min; } }

Write cout after for loop ends

Write cout after for loop ends

Yes

I did and it worked Thanks btw

What code should I use for moving any objects c++

Like for example if I where to move the "hello world " which code can I use

Like for example if I where to move the "hello world " which code can I use

This needs more explanation or an example, because it's really unclear what are you asking about

#include<bits/stdc++.h> using namespace std; int main () { int N,M,max=INT_MIN,index = 0; cin>>N; for(int i = 0;i<N;i++) { cin>>M; } for(int i = 0;i<N;i++) if (max<M) { index = i + 1; } cout<<index; return 0; }

What's wrong with this code ?

I'm new to programming so I'm having difficulty explaining...but what I mean is when u build and run your program without any codes put it..I'm using code blocks it displays "Hello world" so if I want to move around that hello world using the ARROW keys how can I do so

#include<bits/stdc++.h> using namespace std; int main () { int N,M,max=INT_MIN,index = 0; cin>>N; for(int i = 0;i<N;i++) { cin>>M; } for(int i = 0;i<N;i++) if (max<M) { index = i + 1; } cout<<index; return 0; }

We measured the amount of rain (in millimeters) for N days. Write a program that determines the day on which the most rain fell.

index is the day on which maximum rain fell

you should use an array to store the detections and then assign the maximum to a variable :)

pretty straightforward

#include<bits/stdc++.h> using namespace std; int main () { int N,M,max=INT_MIN,index = 0; cin>>N; for(int i = 0;i<N;i++) { cin>>M; } for(int i = 0;i<N;i++) if (max<M) { index = i + 1; } cout<<index; return 0; }

#include<bits/stdc++.h> using namespace std; int main () { int N,M,max=INT_MIN,index = 0; cin>>N; for(int i = 0;i<N;i++) { cin>>M; } for(int i = 0;i<N;i++) if (max<M) { index = i + 1; } cout<<index; return 0; }

You are overwriting M, M will have only one value i.e. final. Try using array or vector

#include<bits/stdc++.h> using namespace std; int main () { int N,M,max=INT_MIN,index = 0; cin>>N; for(int i = 0;i<N;i++) { cin>>M; } for(int i = 0;i<N;i++) if (max<M) { index = i + 1; } cout<<index; return 0; }

you should use an array

So i should use array for M ?

Don't about vectors 👀

Don't about vectors 👀

Use array then

#include<bits/stdc++.h> using namespace std; int main () { int N,M,max=INT_MIN,index = 0; cin>>N; for(int i = 0;i<N;i++) { cin>>M; } for(int i = 0;i<N;i++) if (max<M) { index = i + 1; } cout<<index; return 0; }

that's the trick, you just have to adapt it to your program int main() { int arr[4] = { 1, 2, 3, 4 }; int max = 0; for ( int i = 0; i < 4; ++i ) { if ( arr[i] > max ) { max = arr[i]; } } std::cout << max << '\n'; }

If you want to move a line of code up or down, then you need to check your IDE settings (the code editor your use) to find what is the shortcut for that. Most of the IDEs use Ctrl+Shift+Up or Ctrl+Shift+Down combinations. Or you can just cut that code line, and paste it where you need it. Anyway if I understanding this question correctly, it's not really related to C/C++

does anyone know how to simulate a concurrent customer - supplier system in c++?

I need help on an assignment

does anyone know how to simulate a concurrent customer - supplier system in c++?

What is a concurrent customer?

So like, a stdin/out kind of project?

means they are running in parallel and the program has to be thread safe, stuff like mutex, locks, queues ….

Ok, but what does it do, tho? You need to multithread something

Hello, I have homework

yes, It generates requests for the customer and also the supplier, multithreads a queue
