A stack is one form of a data structure. At any particular instance, only the top of the stack is accessible, which means that in order to retrieve data that is stored inside the stack, those on the upper part should be extracted first. When writing programs that will store and retrieve data in a file, it is possible to designate that file into different forms. A sequential access file is such that data are saved in sequential order: one data is placed into the file after another. To access a particular data within the sequential access file, data has to be read one data at a time, until the right one is reached.

SAP User Security. Polymorphism, virtual function, inheritance, Operator overloading, namespace concepts are not available in C programming language. C languages give importance to functions rather than data.

So, data and function mapping is difficult in C. C language does not support user define data types. Exception handling is not present in C programming language. C language allows data to freely flow around the functions. C language is belonging to middle level language. I am a fresher candidate. So i have no idea about that.

I am last year engineering student, But I cant decide which is best field for my future as per knowledge. When dreaming for Software companies, C is one of the necessity to have a grip on. Thus this questions if not totally but will help you know the type mostly seeked by the interviewers.

Anonymous says: Nanndhini says: Azhahesan says: Ria Roy says: Sindhu Kumari says: Narayani says: Avinash Hari Patil says: It is made up of the commands and other English-like keywords that are supposed to instruct the computer what to do.

However, computers would not be able to understand source codes. Therefore, source codes are compiled using a compiler. The resulting outputs are object codes, which are in a format that can be understood by the computer processor. In C programming, source codes are saved with the file extension. C, while object codes are saved with the file extension.

This is a common problem for beginners because quotes are normally part of a printf statement. It is referred to as a terminating null character, and is used primarily to show the end of a string value.

It is used to assign a value to a given variable. The modulus operator outputs the remainder of a division. For example: A nested loop is a loop that runs within another loop. Put it in another sense, you have an inner loop that is inside an outer loop. In this scenario, the inner loop is performed a number of times as specified by the outer loop. For each turn on the outer loop, the inner loop is first performed. Instead, the operator! Compilers and interpreters often deal with how program codes are executed.

Interpreters execute program codes one line at a time, while compilers take the program as a whole and convert it into object code, before executing it. The key difference here is that in the case of interpreters, a program may encounter syntax errors in the middle of execution, and will stop from there. On the other hand, compilers check the syntax of the entire program and will only proceed to execution when no syntax errors are found.

The char keyword can only hold 1 character value at a time. By creating an array of characters, you can store string values in it. While curly brackets are mainly used to group several lines of codes, it will still work without error if you used it for a single line.

Some programmers prefer this method as a way of organizing codes to make it look clearer, especially in conditional statements. Header files are also known as library files. They contain two essential things: Simply put, commands that you use in C programming are actually functions that are defined from within each header files. Each header file contains a set of functions. Syntax errors are associated with mistakes in the use of a programming language. It maybe a command that was misspelled or a command that must was entered in lowercase mode but was instead entered with an upper case character.

A misplaced symbol, or lack of symbol, somewhere within a line of code can also lead to syntax error. Variables and constants may at first look similar in a sense that both are identifiers made up of one character or more characters letters, numbers and a few allowable symbols. Both will also hold a particular value. Values held by a variable can be altered throughout the program, and can be used in most operations and computations. Constants are given values at one time only, placed at the beginning of a program.

This value is not altered in the program. For example, you can assigned a constant named PI and give it a value 3. You can then use it as PI in the program, instead of having to write 3.

Arrays contain a number of elements, depending on the size you gave it during variable declaration. Each element is assigned a number from 0 to number of elements To assign or retrieve the value of a particular element, refer to the element number. Since each header file contains different function definitions and prototype, you would be using only those header files that would contain the functions you will need. Declaring all header files in every program would only increase the overall file size and load of the program, and is not considered a good programming style.

When declaring functions, you will decide whether that function would be returning a value or not. Compound statements are made up of two or more program statements that are executed together. Compound statements can also be executed within a loop. Before a program can be written, an algorithm has to be created first.

An algorithm provides a step by step procedure on how a solution can be derived. It also acts as a blueprint on how a program will start and end, including what process and computations are involved. When storing multiple related data, it is a good idea to use arrays. This is because arrays are named using only 1 word followed by an element number.

With arrays, only 1 name is used, the rest are accessible through the index name grade[0], grade[1], grade[2]… grade[9].

This is a common mistake for programmers, often leading to logical errors. Random numbers are generated in C using the rand command.

The most probable reason behind this error is that the header file for that function was not indicated at the top of the program.

Header files contain the definition and prototype for functions and commands used in a C program. Comments are a great way to put some remarks or description in a program. It can serves as a reminder on what the program is all about, or a description on why a certain code or function was placed there in the first place. Comments can be a single line, or can even span several lines.

It can be placed anywhere in the program. Debugging is the process of identifying errors within a program. During program compilation, errors that are found will stop the program from executing completely.

At this state, the programmer would look into the possible portions where the error occurred. Debugging ensures the removal of errors, and plays an important role in ensuring that the expected program output is met. When using this operator, all conditions specified must be TRUE before the next action can be performed. There is no single command or function in C that can check if a number is odd or even.

However, this can be accomplished by dividing that number by 2, then checking the remainder. If the remainder is 0, then that number is even, otherwise, it is odd. You can write it in code as:.

This format is used for two things: The number before the decimal point is for the allotted space, in this case it would allot 10 spaces for the output number.

If the number of space occupied by the output number is less than 10, addition space characters will be inserted before the actual output number.

Program that contains logical errors tend to pass the compilation process, but the resulting output may not be the expected one. This happens when a wrong formula was inserted into the code, or a wrong sequence of commands was performed. Syntax errors, on the other hand, deal with incorrect commands that are misspelled or not recognized by the compiler.

There are 3 main control structures in programming: Sequence, Selection and Repetition. Sequential control follows a top to bottom flow in executing a program, such that step 1 is first perform, followed by step 2, all the way until the last step is performed.
