Hello guys, how are you? I have a quick question, are we allowed to share job opportunities here?

## Rules #pinned * You are not entitled to an answer, getting angry about not answered questions will get you warned. * Not checking your problem in google (or any other search engine) first will get you a warn. * Asking to solve an assignment/test/whatever without trying it first yourself will get you a warn or will get you BANNED. We won’t write a code for you, but we can push you forward and suggest something. * Before posting a long code snippet think twice and read the Resources section below. * No “best book” or “best youtube channel” requests, use /get cbook and /get cppbookguide chat commands. * No “best ide” requests, use /get ide chat command to see the suggestions. * Asking for something that is in the pinned message right after joining WILL GET YOU BANNED. * C/C++ discussion preffered (assembly also allowed), asking about other languages (or groups for other languages) right after joining will get you BANNED. * Reverse enginnering, hacking and related topics are allowed, but asking to hack facebook, instagram, etc. is NOT allowed. Also if you ask "how to become a hacker" and obviously have zero knowledge on anything related to that you may get warned or banned. * Legitimate requests for help on code and programming questions are welcome. A request is considered legitimate if it describes your problem, what you've done so far and what went wrong. Requests such as "write my program" or "do my homework" are never considered legitimate. Asking not legitimate questions will result in a warn or ban. See https://stackoverflow.com/help/mcve on how to write good questions. * Asking for book recommendations is ok, but "pls give pdf book" is not allowed, find books by yourself. Posting illegally copied books (or links to those books) is also not allowed and will get you BANNED. * Only English language is allowed, if you speak shitty English or don't understand anything in English YOU WILL BE BANNED. * A little bit of programming related memes, jokes, shitposting are allowed. * NSFW content (porn, nudity, etc.) is not allowed. * Spamming/advertising (job posts are also ads, so ask an admin before posting) will grant you a warning or an immediate ban if you do it right after joining. * Religion, politics and ideological topics are forbidden. * Long code snippets must be posted via a snippet website(links below), posting pictures of code and posting long snippets in the group is not allowed. * If you encounter a problem, while using dev C++ or turbo C/C++, you will not be helped, use another more modern IDE. * Don't post compiled executables, that is obviously a security risk. * Personal messages without asking beforehand are not allowed. * If you want to post a link or some article in this chat you will need an admin approval first ## Resources C/C++ group India: http://t.me/c_cpp_india About asking good questions: * [English](http://www.catb.org/esr/faqs/smart-questions.html) * [Translations](http://www.catb.org/esr/faqs/smart-questions.html#translations) For posting long code snippets: * [GitHub Gist](https://gist.github.com) * [Ubuntu Paste](https://paste.ubuntu.com/) * [Pastebin](https://pastebin.com) ## Reports If you notice any forbidden content, please use the /report command while responding to the offending post to report it to the admins.

Usually that leads to a instaban :P

Also you might want to read the rules which have a SPECIFIC section about it.

I want to make a project for college But I don't know what to make

I want to make a project for college But I don't know what to make

and Learning GUI in C would polish my skills in C

What should I do?

No No I am supposed to use entirely C

I am thinking maybe a game or sth

I wanted to add GUI to make it appealing

I have made Tic-tac-toe console based

@VoidStar0x0 You're a C programmer?

What is meant by hidden test case?

But after that I submit my code that displays as hidden test case!

No No I am supposed to use entirely C

#include<iostream> using namespace std; class student{ int scores[5]; public: void input(int, int, int, int, int); int calculateTotalScore(); }; void student::input(int a , int b, int c, int d , int e){ scores[0]=a; scores[1]=b; scores[2]=c; scores[3]=d; scores[4]=e; } int student::calculateTotalScore(){ int sum; sum=(scores[0]+scores[1]+scores[2]+scores[3]+scores[4]); return sum ; } int main(){ int n,a,b,c,d,e; cout<<"total students"<<endl; cin>>n; class student obj[n]; for (int i = 1; i <= n; i++) { cout<<"enter the marks of "<<endl; cin>>a>>b>>c>>d>>e; obj[i].input(a,b,c,d,e); obj[i].calculateTotalScore(); } return 0; }

What is meant by hidden test case?

The test cases which are kept secret. It is just to ensure that you can't cheat by looking at the test cases and write exclusive conditions for those!

I am beginner I don't know how to do that

#include<iostream> using namespace std; class student{ int scores[5]; public: void input(int, int, int, int, int); int calculateTotalScore(); }; void student::input(int a , int b, int c, int d , int e){ scores[0]=a; scores[1]=b; scores[2]=c; scores[3]=d; scores[4]=e; } int student::calculateTotalScore(){ int sum; sum=(scores[0]+scores[1]+scores[2]+scores[3]+scores[4]); return sum ; } int main(){ int n,a,b,c,d,e; cout<<"total students"<<endl; cin>>n; class student obj[n]; for (int i = 1; i <= n; i++) { cout<<"enter the marks of "<<endl; cin>>a>>b>>c>>d>>e; obj[i].input(a,b,c,d,e); obj[i].calculateTotalScore(); } return 0; }

when you call cin>>n; you are implicitly converting the character the user presses to a number. the character the user inputs is an ascii character, so if for example the user inputs '4', the value of n it will not be 4, instead it will be 52. I cannot attach images, but you can search in google "ascii table" and search for converting strings to integers

#include<stdio.h> #include<conio.h> void main() { int h=0,m=0,s=0; printf("enter a time formate in HH:MM:SS"); scanf("%d%d%d",&h,&m,&s); start: for(h;h<24;h++) { for(m;m<60;m++) { for(s;s<60;s++) { printf("%d:%d:%d",h,m,s); if(h<12) { printf("AM"); } else { printf("PM"); } for(double i=0;i<3619999;i++) i++; i--; } s=0; } m=0; } h=0; goto start; return 0; }

Show error please help

#include<stdio.h> #include<conio.h> void main() { int h=0,m=0,s=0; printf("enter a time formate in HH:MM:SS"); scanf("%d%d%d",&h,&m,&s); start: for(h;h<24;h++) { for(m;m<60;m++) { for(s;s<60;s++) { printf("%d:%d:%d",h,m,s); if(h<12) { printf("AM"); } else { printf("PM"); } for(double i=0;i<3619999;i++) i++; i--; } s=0; } m=0; } h=0; goto start; return 0; }

There are so many mistakes...

Please solve it

#include<stdio.h> #include<conio.h> void main() { int h=0,m=0,s=0; printf("enter a time formate in HH:MM:SS"); scanf("%d%d%d",&h,&m,&s); start: for(h;h<24;h++) { for(m;m<60;m++) { for(s;s<60;s++) { printf("%d:%d:%d",h,m,s); if(h<12) { printf("AM"); } else { printf("PM"); } for(double i=0;i<3619999;i++) i++; i--; } s=0; } m=0; } h=0; goto start; return 0; }

You are already declaring h, m and s variables, so no need to write h m s inside the loop parenthesis.

Int *idx=upper_bound(Y,Y+n,X); Here Y is an array... Int ans=(Y+n)-idx; Idx is an adress then for ans to be number of elements in between we need to divide it by size of int no?? Why is it still giving the correct ans

When you subtract two pointers within the same array (or one past the array) the resultant type is ptrdiff_t which indicates the number of elements of the type that the pointer points to in the range. You dont have to divide it by sizeof(<element type>).

When do I have to divide by type then

When you deal with bytes. For ex sizeof returns the number of bytes used for object representation in memory.

His is it possible to run two loops simulateously? It's for a race simulation.

Is there a data structure that holds N element and pushes older ones back when a new one is added, but never grows and just drop the oldest element when it gets full?

you mean queue?

that sounds right
