Here is the list of over top C Programming Questions and Answers. All solutions are in C language. To summarize our programming questions list does not contain only answers In addition to, it also contains all the aspect of the problem, if any programming questions have multiple solutions then we try to add all possible solution of the problem actually programming problem. We also divide all the c programming questions to multiple levels. Levels are nothing but complexity and toughness of programming questions.

C Programming Tricky Interview Questions

Dear readers, these C Programming Interview Questions have been designed specially to get you acquainted with the nature of questions you may encounter during your interview for the subject of C Programming. It de-refers twice to point to the data held by the designated pointer variable. By default every local variable of the function is automatic auto. Break can appear only with in the looping control and switch statement.

The purpose of the break is to bring the control out from the said blocks. When control reaches for expression-1 is executed first. A static local variables retains its value between the function call and the default value is 0.

The following function will print 1 2 3 if called thrice. If a variable is used most frequently then it should be declared using register storage specifier, then possibly the compiler gives CPU register for its storage to speed up the look up of the variable.

A pointer initially holding valid address, but later the held address is released or freed. Then such a pointer is called as dangling pointer. It is used to alias the existing type. Also used to simplify the complex declaration of the type. The expression appearing on right side of the assignment operator is called as rvalue.

Rvalue is assigned to lvalue, which appears on left side of the assignment operator. The lvalue should designate to a variable not a constant. The parameters sent to the function at calling end are called as actual parameters while at the receiving of the function definition called as formal parameters.

When we do not know what type of the memory address the pointer variable is going to hold, then we declare a void pointer for such. A structure containing the same structure pointer variable as its element is called as self-referential structure. No, the header file only declares function. The definition is in library which is linked by the linker. More generic functions definition gives the ability to re-use the functions, such as built-in library functions. A C program consists of various tokens and a token is either a keyword, an identifier, a constant, a string literal, or a symbol.

Preprocessor is a directive to the compiler to perform certain things before the actual compilation process begins. Yes, if it is not appearing as the last case and if we do not want the control to flow to the following case after default if any.

We can create integer structure members of differing size apart from non-standard size using bit fields. Such structure size is automatically adjusted with the multiple of integer size of the machine. The arguments which we pass to the main function while executing the program are called as command line arguments.

The parameters are always strings held in the second argument below in args of the function which is array of character pointers. First argument represents the count of arguments below in count and updated automatically by operating system.

We choose this if we do not want the actual parameters to be modified with formal parameters but just used. We choose this if we do want the actual parameters to be modified with formal parameters. Opens a file both for reading and writing. If a file is not existing it creates one, else if the file is existing it will be over written. A pointer holding the reference of the function is called pointer to a function. In general it is declared as follows.

You would make a function static if it should be called only within the same source code. Enumerations are list of integer constants with name. Enumerators are defined with the keyword enum. In first place they are non-standard keywords. Both the keywords are implementation specific and are non-standard. A value which cannot be modified is called so. Such variables are qualified with the keyword const.

Further you can go through your past assignments you have done with the subject and make sure you are able to speak confidently on them. If you are fresher then interviewer does not expect you will answer very complex questions, rather you have to make your basics concepts very strong. Second it really doesn't matter much if you could not answer few questions but it matters that whatever you answered, you must have answered with confidence.

So just feel confident during your interview. We at tutorialspoint wish you best luck to have a good interviewer and all the very best for your future endeavor. Cheers C Programming Interview Questions Advertisements. Previous Page. Next Page. Previous Page Print Page. Dashboard Logout.

What is a pointer? A pointer is a special variable, which stores the memory address. Ampersand in front of a variable gets its address and asterisk in front of a pointer gets its value. What is null pointer? Null pointer is a pointer which cannot point to anywhere in the program, but uninitialised pointer can point to anywhere in the users program. In C, if the pointer tried to access 0th location, operating system kills the running program because operating system does not allow to access 0 th value. Define function pointer?

It is referred to as a terminating null character and is used primarily to show the end of a string value. Answer: Break is used to control out of the block of code which is executing, we can use in loop statements or switch statements. Answer: The main function in c is the one which executes which you run the program but it is not the first function to be executed as there is another start function which gets executed to compile the libraries.

C is a mid-level and procedural programming language. The Procedural programming language is also known as the structured programming language is a technique in which large programs are broken down into smaller modules, and each module uses structured code. This technique minimizes error and misinterpretation.

Dear readers, these C Programming Interview Questions have been designed specially to get you acquainted with the nature of questions you may encounter during your interview for the subject of C Programming. It de-refers twice to point to the data held by the designated pointer variable. By default every local variable of the function is automatic auto.

There are actually two ways you can do this. Likewise, the statement "x --" means to decrement the value of x by 1. When using Call by Value, you are sending the value of a variable as parameter to a function, whereas Call by Reference sends the address of the variable. Also, under Call by Value, the value in the parameter is not affected by whatever operation that takes place, while in the case of Call by Reference, values can be affected by the process within the function. How does this aid in debugging? The idea is that if the code is in fact correct, you simply remove the comment symbols and continue on.

C programming language was developed at Bell Laboratories in Programming language is nothing but a language designed to communicate to machines through instructions and commands. Normally machines are computers. NET, Python etc. It is a programming techniques that assumes the disciplined use of a few coding structures and the use of top down concepts to decompose main functions into lower level components for modular programming. The main aim of this technique is to improve the programming process through better organization and with better programming notations to facilitate correct and clear description of data and control structures.

Это означает конец нашей разведки. Но мысли Сьюзан были далеко от политических последствий создания Цифровой крепости. Она пыталась осознать истинный смысл случившегося. Всю свою жизнь она посвятила взламыванию шифров, отвергая саму возможность разработки абсолютно стойкого шифра. Любой шифр можно взломать - так гласит принцип Бергофского. Она чувствовала себя атеистом, лицом к лицу столкнувшимся с Господом Богом. - Если этот шифр станет общедоступным, - прошептала она, - криптография превратится в мертвую науку.

Главный криптограф АНБ испробовала все - подмену букв, шифровальные квадраты, даже анаграммы. Она пропустила эти слова через компьютер и поставила перед ним задачу переставить буквы в новую фразу. Выходила только абракадабра. Похоже, не один Танкадо умел создавать абсолютно стойкие шифры. Ее мысли прервал шипящий звук открываемой пневматической двери. В Третий узел заглянул Стратмор.
