In the code you posted, the forward declaration can not work. If it worked in your code, it may be including c.h without your knowing, maybe indirectly through another header.
If #include doesn't work, read the error message. The only reasons for #include not working that I can think of is that either the code in your c.h has a syntax error, or you forgot to add an Include guard[^], causing a duplicate definition.
GOTOs are a bit like wire coat hangers: they tend to breed in the darkness, such that where there once were few, eventually there are many, and the program's architecture collapses beneath them. (Fran Poretto)
This question is the result of too much abstraction in education of computer scientists!
A bit of learning of how a compiler works, Things like Bits and Bytes, the underlying mechanisms, and what it cannot do would help you here. This is an insolvable problem! Ultimately, a compiler lays out code, reserves blocks of memory of a certain size, etc.
The compiler needs to know how much memory is needed for each user defined type (in C(++)) that is a union, structure or a class!
When you Declare a class, you tell the compiler to take note of the name of the class! The Linker may than be able to find that class properly defined in another file, and hence in another .obj file! The compiler cannot at that stage know anything about the size of the object, so, all you can use is either a pointer of an object of that type, or, a reference to it! A Reference to an object is very similar to a pointer, it is a compiler guaranteed pointer, that cannot be null, and always points at an object of the type!
In Your code class 'c' needs to be defined in the file before class a in which it is used! Otherwise your compiler cannot calculate the size of class a!
Best of luck learning more,
There may be rules around this conundrum in synthetic languages such as C#,Java etc. I would know nothing of these! There are no such shortcuts in C or CPP!
I encourage anyone to take up C or CPP! It are the base languages on which all others are built! A knowledge of Machine Code, and how it translates in ASM, would also help you
The question was-[![Go to the link]]
for(i=0;i<r;i++) //taking the input row wise
for(i=1;i<(r-1);i++) //Taking the inner elements
if (counter ==t) //Checking whether the counter equals the inner elements
printf("No peninsular elements");
My logic is to take each inner element and then find its surrounding element. If the surrounding element is 0, then I am increasing my count by 1 otherwise I am increasing counter by 1. If my count equals 3 at the end of the loop, then I am printing that element.
I am getting a private test case failed error when I am running it on my university site. Is there any flaw in my logic that I can rectify to overcome this error.
Am trying to use the clistctrl class using c++/MFC and Microsoft Visual studio 2017. I have designed a report style control with four columns. I am unable to display columns two through four. Am using InsertColumn method to establish the columns, the insertItem method to display the first column and the SetItem method to display columns two through four. I have followed the examples from all around the internet. Only the column headers & the first column are displayed. Is there anyone out there that has gotten this to work? If so could you reference the successful code.
We do not do your homework: it is set for a reason. It is there so that you think about what you have been told, and try to understand it. It is also there so that your tutor can identify areas where you are weak, and focus more attention on remedial action.
Try it yourself, you may find it is not as difficult as you think!
If you meet a specific problem, then please ask about that and we will do our best to help. But we aren't going to do it all for you!

Hello, Maybe you did not understand what I asked, I did not ask you to do my homework, I meant I need someone to help me and give me some useful sites that can help me because I'm a beginner ok where do you see that I asked someone to do my project
I need someone to help me and give me some useful sites that can help me because I'm a beginner
So you can turn in someone else's work as your own? Erroneous assumption on my part, you say? Doubtful, but I will be glad to admit if I am wrong.
Am I correct in assuming this is not your first assignment? As such, the assignments prior to this should have prompted you to create a foundation for which to build, assuming you paid attention in class and did all of the work yourself. Short of looking up API documentation, the WWW should be the last place you should go for help. With a seemingly endless supply of data and information, it's actually making each successive generation less smart than the generation before. Once you figure out why that is, you can actually stop the trend.
There will always be coat tails to ride. Every now and again a person will get tired of that scenery and will decide to wear his/her own coat.

yes you are wrong This is my first assignment i’m a student but i wanted to learn how to create games and I was hoping that i can find someone who have experience and discuss with him how can I start and what should i learn first Because I have never created a game and I want it to be the first time but I was wrong to came here assuming that someone can lead me and give me advices but I will lead myself thank you very much for your help
But i learned that your best teacher is your last mistake
