Input by user

2) C Program to take input from user :

   Logic:- for taking input scanf() is used, which required header file , stdio.h
  How to use:- suppose user enter 10 it is store in int type variable x , so in scanf we provide where 10 is store in memory, such as in program, &x (means in the address of x, where x is a int type variable)
Example:-

Functions:---

Definition:- it is basically a piece of code it has name for identification a function can be called multiple times to maintain the reusability and modularity. by writing function we can avoid same writing/piece of code Function aspects:-  3 aspects of function are 1.function declaration:- a function must be declared globally in c , to tell the compiler about function name, function return type, function parameter.           Syntax:-   return_type function_name(arguments or data_types parameter);              example:-   void sum(int a,int b); 2.function call:-  a function can be called anywhere from the program, pass the same no. of parameter as we write in function declaration.         Syntax:-   function_name(argument_list)             example:-   sum(a,b) 3.function definition:-  it contains the actual statements whi...

Introduction to C

About C:- C is a high-level language . It was initially first developed by D ennis Ritchie in 1972. It was developed to overcome the limitation of previous language such as B,BCPL etc. It was developed for Unix operating System It inherits many features of previous language Features/Advantage:- Simple :- because it provide data types, library function etc. Machine Independent or Portable:- because it can be executed on different machine Procedural language:- Instruction in c program are executed step by step Structured programming language:- break the problem into parts It provide dynamic memory allocation , pointers etc. Speed:-It is faster than another programming language like java, python etc. Disadvantage of C:- It does not support oops concept in which inheritance, polymorphism, encapsulation etc. come. It does not support namespace concept It does not support constructor and destructor There is lack of excepti...

Type casting

type casting or type conversion  allows us to convert one data types into another.for type casting cast operator is required. Syntax:--      (type)expression or value; Example:       int f =9/4; //without type casting       o/p=2       float f=(float)9/4;  //with type casting       o/p=2.3 Type conversion are of two types: 1)Implicit Type Conversion:-  it is also known as automatic type conversion.When the type conversion is performed automatically by the compiler,such type of conversion is known as implicit type conversion. 2)Explicit Type Conversion:-  the type conversion performed by the programmer is known as explicit type conversion.which is done by cast operator as above mentioned.
