Find the area of a circle using c programming -

  Find the area of a circle using c programming -

We can easily find the area of a circle in c programming using simple methods such as printf and scanf. the area of a circle is = PI* Radius* Radius.

                             

Area of circle 

CODE:-

#include<stdio.h>
int main()
{
 float r,pi=3.14,area;
 printf("Enter the value of radius :");
 scanf("%f",&r);
 area= pi*r*r;
 printf("The value of area is  %f ",area);
 return 0;
}         
                


OUTPUT:-
 
 ENTER THE VALUE OF RADIUS:
 5
 THE VALUE OF AREA IS 78.50

Program to find Smallest element in an array using C

  Program to find Smallest element in an array using C We will find the smallest or minimum element in an array using the C concept. We apply an algorithm that assumes the first element as the smallest element and then compares it with other elements if an element is smaller than it then, it becomes the new smallest element, and this process is repeated till the complete array is scanned. ALGORITHMS:-  STEP 1:-    Initialize the required variables. STEP 2:-  Take the input from the user. STEP 3:-   Assume the smallest element is present at the first position. STEP 4:-    Scan each element with the help of for a loop. STEP 5: -    Check if the element Scanned is new smaller than small. STEP 6:-    If it is smallest than small, change the value of small. STEP 7:-    Print small as it stores the smallest element of the array. CODE:- #include <stdio.h> int  main() {      int  a[ 50 ],p,...

Write a C program to find number is Abundant number or not

  Write a C program to find the number is an Abundant number or not:- In this program to find a number is an Abundant number or not. A number n is said to be an Abundant Number to follow these condition the sum of its proper di visors is greater than the number itself. And the difference between these two values is called abundance. Ex:-  Abundant number  12 having a proper divisor is 1,2,3,4,6 the sum of these factors is 16 it is greater than 12 so it is an Abundant number. Some other abundant numbers     18, 20, 24, 30, 36, 66, 70, 72, 78, 80, 84, 88, 90, 96, 100, 102, 104, 108, 112, 114, 120.. ALGORITHMS:- Step 1 - Enter the number, to find the Abundant number. Step 2 - Initialize the loop with c=1 to c<=number and follow the following calculation      (i) check if whether the number is divisible with c and c got a result zero.      (ii) now sum=sum+c, add a digit into a sum and store it in the sum. Step 3 . then the...

How to check if the given number is Even or odd-

1. How to check if the given number is Even or odd- We can determine whether a number is even or odd. This can be tested using different methods. The test can be done using simple methods such as testing the number’s divisibility by 2. If the remainder is zero, the number is even. If the remainder is not zero, then the number is odd. The following algorithm describes how a C program can test if a number is even or odd. CODE:- #include <stdio.h> int   main () { int num;//variable declaration printf("Enter any num: ");// take input from user  scanf("%d",&num);// declare input if(num%2==0) { printf("The num %d is even",num); } else { printf("The num %d is odd",num); } return 0; }     ALGORITHM:- Step 1.   Start Step 2 .   Enter a number. Step 3.   If...
