PART I BASIC QUESTIONS OF C

Hey friends! in this article I will discuss all the most important basic
questions of c programming language
Before further wasting anytime
let's get started.
                                     


Q1- What are the key features in C programming language?
  • Portability – Platform independent language.
  • Flexibility – The possibility to a programmer to control the language.
  • Modularity – Possibility to break down large programs into small modules.
  • Extensibility – Possibility to add new features by the programmer.
  • Speed – C comes with support for system programming and hence it is compiling and executes with high speed when comparing with other high-level languages.
Q2- What are reserved words with a programming language?

       i)Keywords are those words whose meaning is already defined by Compiler.
       ii)There are 32 Keywords in C.
       iii)Cannot be used as Variable Name.
       iv)Keywords are also called as Reserved words .

Q3-  What is the difference between ++i and i++?

  ‘++i”  is called prefixed increment and the increment will happen first on a 
   variable. ‘i++' is called postfix increment and the increment happens after 
   the value of a variable used for the operations.

Q4- Describe the difference between = and == symbols in C programming?
   
   ‘==' is the comparison operator which is use to compare the value
    or expression on the left-hand side with the value or expression 
    on the right-hand side.

     ‘=' is the assignment operator which is use to assign the value of 
     the right-hand side to the variable on the left-hand side.


Q5- Describe the header file and its usage in C programming?

   The file contains the definitions and prototypes of the functions being 
   used in the  program are called a header file. It is also known as a library file.

Q6- What is a nested loop?

  
   A loop running within another loop is referred as a nested loop
  The first loop is called Outer loop and inside the loop is called Inner loop.

Q7- What is a pointer on a pointer in C programming language?

   A pointer variable that contains the address of another pointer variable is 

   called pointer on a pointer. This concept de-refers twice to point to the data 
   held by a pointer variable.

Q8- Is it possible to use curly brackets ({}) to enclose single line code in C program?

  Yes, it is working without any error. Some programmers like to use this to 
  organize the code. But the main purpose of curly brackets is to group 
  several lines of codes.

Q9- What is the explanation for modular programming?


  The process of dividing the main program into executable subsection

  is called module programming. This concept promotes the reusability.

Q10-  Is that possible to store 32768 in an int data type variable?


 Int data type only capable of storing values between – 32768 to 32767.

 To store 32768 a modifier needs to use with int data type. Long Int can 
 use and also if there is no any negative values  unsigned int is also 
 possible to use.
