C Programming Interview Questions (Part-1) | Read Now

C Programming computer language was innovated in the year 1970 but was authorized and permitted to utilize by ANSI in the year 1988. It was centrally invented to code for the OS of UNIX. Currently, C is the prominent computer language utilized by the individuals.

In this post, C Programming Interview Questions, the prominent questionnaire asked in the interviews for cracking and landing a job or internship smoothly are listed out.

1] Emphasize the foundational data-types employed in C computer language.

  1. Basic: The arithmetic sorts of info are contained
  2. Void: Zero or no info is contained
  3. Enumerated: Arrays sort, pointers, functionality type, etc. are contained
  4. Derived: The arithmetic sorts of info but only to declare numerous variables are contained

2] Why is the C computer language termed as “Mother” computer language?

  • Since most interpreters and JVMs are developed in C computer language, it is characterized as a mother computer language.
  • Most technologies born after C have extensively drawn from it, such as C++, Rust, Python, JavaScript, and so on.
  • It brings new underlying principles employed in multiple computer languages, including array, procedures, and document management.

3] What the terminology of “Dangling-pointers” in C computer language mean?

  • In C computer language, the pointers are employed to navigate to an underlying variable’s program memory.
  • When that variable is destroyed but the Pointer continuously refers to same memory area, that variable is termed to as a Dangling-Pointer.

4] Explain the central purpose of C computer language be characterized as “Mid-stage” computer language.

  • C computer language is regarded to as a mid-level computer language since it facilitates communication between low-stage and high-stage programming.
  • We can employ the C computer language for both process standardization and application program interfaces to create a productive systems.

5] Brief on the terminology of “Initializing some Variable” with its significance precisely in C computer language.

  • This is the methodology of allocating a preliminary variable value before it is employed in a code.
  • If the initialization of variable is not accomplished, it will have an unknown or strange value, which might cause in unexpected consequences when employed in simulations and other activities.

6] Elaborate on the terminology “Sequential/Linear accessible files” in C computer language.

  • It is feasible to partition a file into several versions while constructing scripts that will recover data in it.
  • Information is held in chronological order in a sequential/linear accessible file: one information is uploaded to the record after another.
  • And get to a detailed data in that linear accessible file, data must be interpret for a while until the appropriate one is noticed.

7] Instead of eliminating script, certain scripting writers employ commenting symbols to troubleshoot their scripts. What does that mean in the sense of troubleshooting?

  • Positioning commenting signs /* */ together around content, often termed as “posting comments off,” is a manner of distinguishing certain script that you suspect is producing system difficulties without eliminating it.
  • The premise is that if the program is right, you can just erase the remark symbols and continue pushing.
  • Also it spares you time and energy by not needing to rewrite the scripts if you unintentionally destroyed them.

8] Elaborate the utilization of variables namely “Static” in C computer language.

  • A variable namely “Static” is a variable which has been designated as static.
  • The state of the static-variable is persisted across successive callbacks of a functionality.
  • The static var is assumed to be zero by defaults. When we modify the parameter, the new quantity or number is allocated to it.
  • The static var is employed as an unique quantity that all operations share.
  • To save storage, the static var is only created once during the storage heap.

9] What the terminology of loop namely “Nested” termed as in C computer language?

  • The term “nested or recursive looping” pertains to a looping that repeats inside the other looping.
  • In other regards, you have an internal looping that is contained within an external looping.
  • In this circumstance, the internal looping is performed as many instances as the external looping specifies.
  • Each turn on the external looping is accompanied by a turn on the internal looping.

10] Point-out the vital characteristics of C computer language.

  1. Simpler: It is simpler to code the scripts in C computer language
  2. Quick processing: The speed or pace of C computer language is instant
  3. Portability: C computer language can be coded and implemented at any system
  4. Adaptable: C computer language is friendly to adapt and operate on the modifications
  5. Structure: C computer language is the structured one as scripts are partitioned into tiny pieces to operate them quicker
  6. Productive management of storage: The procedure of C computer language to save its system space or storage is appreciable
