Write a program to print automorphic numbers between 1 and 100?
import java.math.*; import java.util.*; class AutomorphicNumber{ static int d=10; public static void main(String args[]){ System.out.print("Enter any number :"); Scanner input=new Scanner(System.in); int n=input.nextInt(); if(d>=n){ if ((n*n) % d == n){ System.out.println("Automorphic Number"); } else{ System.out.println("Not Automorphic Number"); } } else if(d<=n){ d=d*10; if ((n*n) %d==n){ System.out.println("Automorphic Number"); } else{ System.out.println("not an automorphic number"); } } } }
Turbo c program that will determine if the input is odd or even number?
#include <stdio.h> int main() { printf("Program to find ODD or Even Number\n"); while(1) { int n = 0; printf("\nEnter a number(-1 for Exit): "); scanf("%d",&n); if( n 0) { printf("%d is a EVEN number.\n", n); } else { printf("%d is a ODD number.\n", n); } } return 0; }
What is the formula to find sum of n even numbers?
Sum = n/2[2Xa1+(n-1)d] where n is last number, a1 is the first number & d is the common difference between the numbers, here d=2 for the even /odd numbers. Sum = n/2 [2Xa1+(n-1)2]
Write a java program to check a number is Armstrong number?
import java.io.*; public class Jerry { public static void main(String as[]) throws IOException { int k=Integer.parseInt(as[0]); int n=k; int d=0,s=0; while(n>0) { d=n%10; s=s+(d*d*d); n=n/10; } if(k==s) System.out.println("Armstrong number"); else System.out.println("not Armstrong number"); } }
