Circumference of Circle in C programming language

     Circumference of Circle 



 



#include<stdio.h>

int main()

{ 

int radius;

float cir;

printf("Enter Radius of the Circle: ");

scanf("%d",&radius);

cir=2*3.14*radius;

printf("Circumference of the Circle: %.2f",cir);

 return 0; 

}


/* OUTPUT:

Enter Radius of the Circle : 5 Circumference of the Circle: 31.40 */

  Introduction of Computer   In this chapter you will learn about: • Computer • Data processing • Characteristic features of computers • Computers' evolution to their present form Computer • The word computer comes from the word "compute", which means, "to calculate" • Thereby, a computer is an electronic device that can perform arithmetic operations at high speed • A computer is also called a data processor because it can store, process, and retrieve data whenever desired Data Processing The activity of processing data using a computer is called data processing  Data is raw material used as input to data processing and information is processed data obtained as output  Computer Fundamentals: Pradeep K. Sinha & Priti Sinha Characteristics of Computers 1. Automatic : it carries out a job normally without any human intervention.  2. Speed : it can perform several billion (10 ^9) simple arithmetic operations per second . 3. Accuracy : it performs every cal...
