CONVERSION

30) C PROGRAM CONVERT DECIMAL NUMBER INTO BINARY NUMBER

LOGIC:- First take any number which is in decimal form, now store the number in variable (n).we know binary no. is in 0 and 1 form only which is produced when number divide by 2 and remainder is in only form of 0 and 1.Store every remainder in an array.Then print the array in reverse order,which is the binary form of the decimal number.

EXAMPLE:-

NOW CONVERT BINARY INTO DECIMAL NUMBER

LOGIC:- For this program we find the decimal number(10 power),so multiply the binary digits from 2 and increase the power of 2 therefore pow function is used which is present in math.h header file.

EXAMPLE:-

TASK """SIMILARLY CONVERT OTHER NUMBERS"""

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...
