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:

THE VALUE OF AREA IS 78.50

HackerRank Tuples Solution in Python

HackerRank Tuples Solution in Python Task Given an integer,n, and n space-separated integers as input, create a tuple, t, of those n integers. Then compute and print the result of hash(t). Note: hash() is one of the functions in the __builtins__ module, so it need not be imported. Input Format The first line contains an integer,n, denoting the number of elements in the tuple. The second line contains n space-separated integers describing the elements in tuple t . Output Format Print the result of hash(t) . Sample Input 0 2 1 2 Sample OUTPUT- 3713081631934410656 n = int(input()) int_list = [int(i) for i in input().split()] int_tuple = tuple(int_list) print(hash(int_tuple))

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 the number is divisible by 2, it is even. Step 4 . If the number is not divisible by 2, it is odd. Step 5. Stop EXAMP

Binary to Decimal conversion program

3. Binary to Decimal conversion program using C language:- The C program converts binary number to decimal number that is equivalent. A decimal number can be attained by multiplying every digit of binary digit with a power of 2 and totaling each multiplication outcome. The power of the integer starts from 0 and counts to n-1 where n is assumed as the overall number of integers in a binary number. Ex:- ( 101100001 ) 2 =( 353 )10 ALGORITHMS:- Step 1: Start Step 3: The user is asked to enter a binary number as an input Step 4: Store the quotient and remainder of the binary number in the variable rem Step 5: Multiply every digit of the entered binary number beginning from the last with the powers of 2 correspondingly Step 6: Repeat the above steps with the quotient obtained until the quotient becomes 0 Step 7: The sum of the numbers will give the decimal number as a result, print the decimal value. Step 8: Stop. CODE:- #includ
