When can you use a pointer with a function? A pointer can be used with a function- When an address is to be passed to a function When an array elements are to be accessed through a function.

Passing base address will give access to the whole array. What is recursion in C? Advantages of using recursion: Is there any demerits of using pointer? List some basic data types in C? In Programming Languages data types are used to define a variable before its use.

Below are list of some basic data types in C language. Plays a role of generic data type. What is a void pointer? What do you understand by normalization of pointers? Explain continue keyword in C. List some applications of C programming language?

Application of C Programming Language To develop embedded software It is to create a computer application It is effective to create a compiler for various computer languages to convert them into low-level language that is the machine understandable language. No, the header file only declares function. The definition is in library which is linked by the linker. Explain modular programming. More generic functions definition gives the ability to re-use the functions, such as built-in library functions.

What is a token? A C program consists of various tokens and a token is either a keyword, an identifier, a constant, a string literal, or a symbol.

Where can I get C Programming Interview Questions and Answers with Explanation?

What is a preprocessor? Preprocessor is a directive to the compiler to perform certain things before the actual compilation process begins.

Can be used to input integer in all the supported format. Does a break is required by default case in switch statement?

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. What are bit fields? 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. What are command line arguments? 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. Which to use when? 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.

C Programming Interview Questions

What is the purpose of built-in stricmp function. It compares two strings by ignoring the case. 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.

It cannot be used on constants.

It cannot be used on variable which are declared using register storage class. Is FILE a built-in data type? No, it is a structure defined in stdio. What is reminder for 5. How many operators are there under the category of ternary operators? There is only one operator and is conditional operator? Which key word is used to perform unconditional branching?

Give the general syntax for the same. A pointer holding the reference of the function is called pointer to a function. In general it is declared as follows. Comma operator can be used to separate two or more expressions. A null statement is no executable statements such as ; semicolon. What is a static function?

You would make a function static if it should be called only within the same source code.

C programming interview questions

Which compiler switch to be used for compiling the programs using math library with gcc compiler? Ellipses … is used for the same. Which built-in library function can be used to re-size the allocated dynamic memory? Array is collection of similar data items under a common name. What are enumerations?

Enumerations are list of integer constants with name. Enumerators are defined with the keyword enum. Which built-in function can be used to move the file pointer internally? Who designed C programming language? Dennis M Ritchie. C is successor of which programming language?

American National Standards Institute. Which operator can be used to determine the size of a data type or variable? Yes, with loss of fractional part. Is a valid octal number? No, it contains invalid octal digits.

Using dynamic memory allocation, your program will access memory spaces as needed.

C Programming Interview Questions and Answers_ C in Depth PDF

This is in contrast to static data structure, wherein the programmer has to indicate a fix number of memory space to be used in the program. Explain How would you place this character as part of the output on the screen? For example, you can write printf? Storing data on the heap is slower than it would take when using the stack. Explain However, the main advantage of using the heap is its flexibility.

Slowness in the heap can be compensated if an algorithm was well designed and implemented. Preprocessor directives are placed at the beginning of every C program. This is where library files are specified, Explain Which would depend on Explain What functions are to be used in the program.

Another use of preprocessor directives is the declaration of constants. Preprocessor directives begin with the symbol. Just the same, s! Order of precedence determines Explain Which operation must first take place in an operation statement or conditional statement. On the top most level of precedence are the unary operators! Instead, use the strcpy function.

To get the length of a string value, use the function strlen. This is because C language is rich in features that make it behave like a high level language while at the same time can interact with hardware using low level methods. The use of a well structured approach to programming, coupled with English-like words used in functions, makes it act as a high level language. On the other hand, C can directly access memory structures similar to assembly language routines.

Source codes in C are saved with. C file extension. Header files or library files have the. H file extension. Every time a program source code is successfully compiled, it creates an. OBJ object file, and an executable. EXE file. Reserved words are words that are part of the standard C language library.It is used for creating software for various applications and even hardware.

What is recursion? It is used to assign a value to a given variable. The lvalue should designate to a variable not a constant. In this scenario, the inner loop is performed a number of times as specified by the outer loop.
