CONCATENATE

38) C PROGRAM TO CONCATENATE OF TWO STRING

 LOGIC:- Take any two strings,either directly or by user.Now for concatenate there are many ways which is shown in example.

EXAMPLE 1 :- BY USING STRCAT() BUILT-IN FUNCTION


EXAMPLE 2 :- WITHOUT USING BUILT-IN FUNCTION


 EXPLANATION:- This program also created by using a function in which we apply the same logic.Here We use a for loop it can be done by using while loop also.In first for loop all character of string is assign in new string s3.So similarly we can assign the all characters of string s2 in string s3,But here is a problem if we try similar way then only string s2 is present in string s3 so to solve this problem the for loop is start with the size of s1 and run it atleast the size of s2 is not come.

EXAMPLE 3 :- BY USING POINTER 

 New Things:- this time we can take the string from user

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.

UNION

Definition:-                 Union is similar to structure, except it allows you to define the variable that share storage spaces.Defining a means creating a new data types. How use union:-                       when we create a structure by using struct keyword, now making a union we just replace the keyword struct with the keyword union , other syntax will be same. Difference  between Structure  and Union:- the only difference between them is in memory. NOTE:-  union is used for low level programming but structure mostly used for high level programming. Program to access union:- """SHARE IT WITH YOUR FRIENDS IF HE DID NOT KNOW""""

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...
