C programming language, the trailblazer of programming dialects, is a procedural programming language. Dennis Ritchie made it as a framework programming language for composing working frameworks. It is one of the most well known programming dialects in light of its construction, undeniable level reflection, machine-autonomous element, and so on and is an extraordinary beginning stage for anybody needing to get into coding.
C is likewise involved a ton in low-level framework programming, implanted frameworks, and equipment. It has likewise been vigorously upgraded throughout the long term and is as yet used to compose complex programming, for example, the FreeBSD working framework and the XNU bit. Low-level memory access, a little assortment of watchwords, and a spotless style are characteristics that make the C language phenomenal for framework programmings, like working framework or compiler improvement.
C is a low-level programming language that can be straightforwardly interacted with the processor. It offers insignificant deliberation and maximal control, making it an alluring choice for engineers who need to compose proficient code.
How to prepare for C language interview?
1. Why is C called a mid-level programming language?
C has attributes of both get together level for example low-level and more elevated level dialects. So subsequently, C is normally called a center level language. Utilizing C, a client can compose a working framework as well as make a menu-driven purchaser charging framework.
2. What are the features of the C language?
A few highlights of the C language are-
It is Straightforward And Effective.
C language is versatile or Machine Autonomous.
C is a mid-level Programming Language.
It is an organized Programming Language.
It has a capability rich library.
Dynamic Memory The executives.
C is really quick.
We can involve pointers in C.
It is extensible.
3. What is a token?
The singular components of a program are called Tokens. There are following 6 sorts of tokens are accessible in C:
Identifiers
Catchphrases
Constants
Administrators
Unique Characters
Strings
4. What is the use of printf() and scanf() functions? Also explain format specifiers?
printf() is utilized to print the result on the presentation.
scanf() is utilized to peruse arranged information from the console.
Some datatype design specifiers for both printing and filtering objects are as per the following:
%d: It's a datatype design specifier for printing and filtering a whole number worth.
%s: It's a datatype design specifier for printing and examining a string.
%c: It's a datatype design specifier for showing and filtering a person esteem.
%f: The datatype design specifier %f is utilized to show and output a float esteem.
5. What's the value of the expression 5["abxdef"]?
The response is 'f'.
Clarification: The string referenced "abxdef" is a cluster, and the articulation is equivalent to "abxdef"[5]. For what reason is the back to front articulation same? Since a[b] is comparable to *(a + b) which is identical to *(b + a) which is comparable to b[a].
6. What is a built-in function in C?
The most ordinarily utilized worked in capabilities in C are scanf(), printf(), strcpy, strlwr, strcmp, strlen, strcat, and some more.
Fabricated capability is otherwise called library works that are given by the framework to make the existence of a designer simple by helping them to do certain normally utilized predefined undertakings. For instance, in the event that you really want to print yield or your program into the terminal, we use printf() in C.
7. What is a Preprocessor?
A preprocessor is a product program that processes a source document prior to sending it to be incorporated. Incorporation of header records, large scale developments, restrictive assemblage, and line control are conceivable with the preprocessor.
8. In C, What is the #line used for?
In C, #line is utilized as a preprocessor to re-set the line number in the code, which takes a boundary as line number. Here is a model for something similar.
#include /*line 1*/
/*line 2*/
int main(){ /*line 3*/
/*line 4*/
printf("Hello world\n"); /*line 5*/
//print current line /*line 6*/
printf("Line: %d\n",__LINE__); /*line 7*/
//reset the line number by 36 /*line 8*/
#line 36 /*reseting*/
//print current line /*line 36*/
printf("Line: %d\n",__LINE__); /*line 37*/
printf("Bye bye!!!\n"); /*line 39*/
/*line 40*/
return 0; /*line 41*/
} /*line 42*/
