C Programming
Questions related to the C Computer Programming Language. This ranges all the way from K&R to the most recent ANSI incarnations. C has become one of the most popular languages today, and has been used to write all sorts of things for nearly all of the modern operating systems and applications. It it a good compromise between speed, power, and complexity.

What is an aggregate constant?
An aggregate constant is a nonscalar constant which value never change or are not changed during execution of the program.
Html vs traditional programming language?
HTML is not a programming language so it is very different to programming languages. HTML is really just for formatting text and laying out pages, what we call marking up a page. So it is a Markup Language. It can't really do anything interactive with you. Web pages that can do things normally have programming code built into them, with languages like Javascript. HTML can't even do simple things like calculations. Calculations are fundamental to programming languages, as are many other things like: making decisions, repeating instructions, storing data, processing data, and many other things. HTML can't do any of those things. HTML borrows some things from programming, like the facility to use comments, encouraging people to lay out their code properly and the use of simple English-like commands.
If people have learned how to use HTML, it is still a big step up to grasp the concepts of programming. There are also very many programming languages, many of them specialising in doing certain kinds of jobs. Many are very complicated and technical and can be quite cryptic, making them hard to learn. They can also be very strict in how you have to do things, and even simple errors can stop your program working. Programming can be very frustrating because of that. You need to learn and understand a lot more things to write programs than you need for creating HTML pages. HTML is a lot less complicated. You can even make some basic mistakes and your page will still work. HTML can be learned very simply and quickly. It is very easy to show someone how to create a simple web page with HTML. So there is a very big difference between HTML and programming languages.
What are the qualifiers that an int can have at a time?
A signed int can take a value between -32768 to 32767 and an unsigned int can take a value 0 to 65535.
How do you find largest of two object using operator overloading in c?
I will not use operator overloading in C# to do anything. Operator overloading may lead to one operator has more than 1 semantic meaning. For example, we know 1 + 2 yields 3, and "1" + 2 yields "12". I do not like this overloading of the operator + being used for addition in Number hierarchy, while as the concatenation in strings. That is, one operator (+) has 2 significant semantics.
And the question "find largest of two object" is too vague - what do you mean "largest"? and object? We know apple and orange are 2 objects, but how do you compare them, and find the largest one?????? (size, price or what???)
How do I round up to the next largest whole number in C plus plus?
It's either floor(x)+1 or ceil(x) depending on what you want to get for integral x numbers:x or x+1
What is your GPA if you have all a's but 1 c plus?
That depends on how many total classes you have.
In other words, how many 'a's ?

How do you obtain a single value from array?
That depends on the language you use, but I guess you're using C. So, here goes:
int x[10] = {0}; //declare an array with ten indexes (0 thru to 9)
printf("%i\n", x[0]); //print x[0], which should be zero.
How do you get your nested loop to decrement and not increment?
Easy. Change any + to -, any += to -=, any ++ to --
How do you do serial port communication between two computers in Linux using c language?
You should use pppd to define a connection between the two computers, then normal TCP/IP networking (telnet, ftp, http, NFS, SMB etc) will work without any programming.
Why loop seal provided in cfbc boiler?

In what way can you benefit from the study of philosophy?

How do you call string function using pointers in main program?
An array name is a pointer, so using arrays as pointers in function calls is implicit. An example is...
char a[] = "This is the source";
char b[sizeof(a)];
strcpy (b, a);
This is exactly the same1 as saying...
char a[] = "This is the source";
char b[sizeof(a)];
strcpy (&b[0], &a[0]);
... or ...
char* ap = "This is the source";
char* bp = malloc(strlen (ap)+1);
if (bp == NULL) { ... handle memory exception ... }
strcpy (bp, ap);
---------------------------------------------------------------------------------------------
1However, while a and ap have the same value in these examples, they are not really the same. You can assign a new value to ap, but not to a, because a is an r-value that is not allocated a place in memory, as opposed to ap, which is a l-value. To reinforce this, both *ap and a[0] are l-values, meaning the same thing, but not quite so for ap and a. Be careful - they both have the same value, but ap is an assignable l-value, while a is a un-assignable r-value.

What is comment in c programming?
COMMENT:- comment a re not necessary in the program. however, to understand the flow of programs the programmer can include comments in the program. comment are to be inserted by the programmer. It is useful for documentation.
Comment are nothing but some kind of statements which are placed between the delimiters /* & */. The compiler does not execute comments. Thus, we can say that comments are not the part of executable program.
The user can frequently use any number of comments that can be placed any where in the program. Please note that the comments and statements can be nested. The user should select the OPTION MENU of the editor and select the COMPILER - SOURCE -NESTED COMMENTS ON/OFF). The Comments can be inserted with a single statement or in nested statement.
Types of comment in c/c++. is following bellow
1. // this is a single line comment
2. /* */ this sing is multi line OR nested line comments
eg. /* int i=90;
char ch=65; */ close multi line comments
