C Program Interview Questions And Answers:
Q. Features of C Programming Language?
Ans: Procedural Language
Fast and Efficient
Modularity
Statically Type
General Purpose Language
Rich set of built in Operators
Libraries with rich Functions
Middle Level Language
Portability
Easy to Extend
Q. What is the main difference between the Compiler and the Interpreter?
Ans: Compiler is used in C Language and it translates the complete code into the Machine Code in one shot. On the other hand, Interpreter is used in Java Programming Language and other high-end programming languages. It is designed to compile code in line by line fashion.
Q. What are different storage class specifiers in C?
Ans: auto, register, static, extern
Q. What is NULL pointer?
Ans: NULL is used to indicate that the pointer doesn’t point to a valid location.
Q. What is Dangling pointer?

Q. What is Preprocessor?
Ans: A Preprocessor Directive is considered as a built-in predefined function or macro that acts as a directive to the compiler and it gets executed before the actual C Program is executed.
Q. What is an array?
Ans: The array is a simple data structure that stores multiple elements of the same datatype.
Q. What is typecasting?
Ans: Typecasting is a process of converting one data type into another is known as typecasting.
Q. What is a nested loop?

Free and Open Source
Object-Oriented Language
GUI Programming Support
High-Level Language

Q. What are functions in Python?
Ans: A function is a block of code which is executed only when it is called. To define a Python function, the def keyword is used.
Q. In Python what is slicing?
Ans: A mechanism to select a range of items from sequence types like list, tuple, strings etc. is known as slicing.
Q. What is a string in Python?
Ans: The string can be defined as the sequence of characters represented in the quotation marks. In Python, we can use single, double, or triple quotes to define a string.
Example: str2 = 'hello world'
Q. What is a Lists in Python?
Ans: Python Lists are similar to arrays in C. However, the list can contain data of different types. The items stored in the list are separated with a comma (,) and enclosed within square brackets [].
example: mylist1 = ["apple", "banana", "cherry"]
Q. What is tuple in Python?
A tuple is a built-in data collection type. It allows us to store values in a sequence. It is immutable, so no change is reflected in the original data. It uses () brackets.
example: tup1 = ("apple", "banana", "cherry")
Q. What is a dictionary in Python?
Ans: The built-in datatypes in Python is called dictionary. It defines one-to-one relationship between keys and values. Dictionaries contain pair of keys and their corresponding values. Dictionaries are indexed by keys.
example: dict={'Country':'India', 'Game':'Cricket', 'Color':'Blue'}
Q. What is the difference between list and tuple?
