#include<stdio.h> #include<string.h> //#define UNIT_COST 450; void main() { float unitsConsumed; char Customername[20]; int customerid; float Totalcost; printf("Enter Customer id:"); scanf_s("%d", &customerid); printf("Enter Customer Name:"); scanf_s("%s", &Customername); printf("Enter Number of units consumed"); scanf_s("%f", &unitsConsumed); Totalcost = 450 * unitsConsumed; printf("Total cost of power is %f", Totalcost); }

In this code I am trying to replace 450 in totalcost assignment with macro constant I defined above but vs code is interpreting * as pointer indirection operator in place of multiplication. How to fix the problem?

remove the semicolon in your #define — 450; * unitsConsumed is not valid

Yeah 👍 it's working

Please I need you guys help I need someone who can ask

How do a person loop in c programming

I am new here can anyone tech me c++

Hi, what is the proper way to get a signal from one thread to another that the work is finished? I spawn a task and give it to another thread and want to stop my thread until the another one is done with processing the task. I don't care about the results, I just need to pause the execution until this moment. I guess I need just an atomic_bool and loop on it in with acquire memory order? Is there a function for that like wait for atomic_flag? Or it will be more effective to use atomic_flag (together with a bool and a mutex)?

// Insertion at begning At Doubly linked list #include<stdio.h> #include<stdlib.h> // structure created struct Node { int data; struct Node * Next; struct Node * prev; }; // traversal void traversal(struct Node * head) { struct Node * ptr = head; while(head->Next!=NULL) { printf("%d ",ptr->data); ptr=ptr->Next; } } // insertion fuction struct Node * InsertionAtbeg(struct Node * head,int value) { struct Node * p = (struct Node*) malloc (sizeof(struct Node)); p->data=value; p->prev=NULL; p->Next=head; head->prev=p; head=p; return head; } int main() { // Dynamic memory allocation struct Node * head = (struct Node*) malloc (sizeof(struct Node)); struct Node * second = (struct Node*) malloc (sizeof(struct Node)); struct Node * third = (struct Node*) malloc (sizeof(struct Node)); struct Node * fourth = (struct Node*) malloc (sizeof(struct Node)); // linking Nodes head->data=32; head->Next=second; head->prev=NULL; second->data=43; second->Next=third; second->prev=head; third->data=23; third->Next=fourth; third->prev=second; fourth->data=85; fourth->Next=NULL; fourth->prev=third; printf("Before the insertion:\n"); traversal(head); printf("After the insertion:\n"); // function calling head=InsertionAtbeg(head,23); traversal(head); return 0; }

Мой выбор из редакторов пал на VS Code. Ну и гитхаб к нему добавлю. VS Code норм будет?) А то раньше пользовался VS 2019, но он очень громоздкий по объему, а функционал вроде не намного больше

Is anyone can give me gcc file ....i can't able to download ...idk why ....

Yeah it is 🤔 When u download the files u will have an ide and a exe file then u should install its ide on dev then it's ready Actually i like VS code but i really confused with installing c++ ide on it 😅 So i decided to work with dev c++ and i found it really interesting

use these. vscode isn't bad, but it is hard to integrate with industry standard tools. the CMake syntax highlighter extension was last updated 3 years ago afaik

Hello Everyone How are you doing?🙂 And why is the rules of this group is so outstanding ?

please don't use dev C++. and other people please don't give bad suggestions (specifically turbo C and dev C).

So according to u dev c++ is not good option for c++ ? Isn't it?

yes.

maybe if it supported at least CMake

yes.

So which is good platform ..for c++?

Does it require compiler ? Like gcc ?

yes. it uses msvc.

Download the "Community 2019" installer

for a basic installation i recommend that you pick the "Desktop development with C++" bundle. Now expand the components on the right hand side of that page. Pick C++ clang tools, C++ CMake tools, and C++ AddressSanitizer from the optional section.

when creating new projects, always pick CMake projects instead of Visual Studio native projects.

Okay....if i get any problem ...can i message u? If u don't have any problem ...this'll really help me

cmake supports almost everything. and whatever it doesn't support can be added to it using custom commands.

try using Visual Studio, Qt Creator, or CLion. the CMake integration they have is on a different level compared to vscode.

I didn't give him bad suggestion bro I just told him my opinion 🤷‍♂️

I'm not in any big project yet but thanks I just got an overview about how cmake, read some answers on stackoverflow 😅

question regarding makefile why when I send this make file to a peer that has the same folders hierarchy it does not work on his laptop

Does anyone live in the UAE or Qatar?

question regarding makefile why when I send this make file to a peer that has the same folders hierarchy it does not work on his laptop

What is the error?

Thank you.

But it seems like this is not my site. I just wanted a place where I can get lessons on programming

Wow

question regarding makefile why when I send this make file to a peer that has the same folders hierarchy it does not work on his laptop

Which platform? Linux? You have dependence and assume that the same environment is being used. Most common would be commands in bash will not work in csh

Also it would be helpful to get some insight I to the "it does not work" any errors/warning messages?

Hello can you help l can't find were lm making an error using namespace std; int main(); { int firstnumber,secondnumber,sumoftwonumbers; cout << "enter two integers: "; cin >> firstnumber >> + secondnumber; cout << "first number " << "+" << secondnumber << " = "<< sumoftwonumbers; return 0; }

Hello can you help l can't find were lm making an error using namespace std; int main(); { int firstnumber,secondnumber,sumoftwonumbers; cout << "enter two integers: "; cin >> firstnumber >> + secondnumber; cout << "first number " << "+" << secondnumber << " = "<< sumoftwonumbers; return 0; }

Assign sum = first + second. Remove + before second in cin.

Also clear your basics first then apply them

What is Segmentation fault?

What is Segmentation fault?

When you access data from memory location which is beyond the allocated memory for your program

Ex. If you have array of length 5 and you try to access 7th index, maybe this error can occur... I said maybe cause it depends on the memory allocated for complete program

I want to do C++ basics question anyone suggest website

Try sanfoundry

Ok
