C Program to Check a given Number is Armstrong or Not

 C Program to Check a given Number is Armstrong or Not.

    In this example, we will check a number entered by the user whether it is an Armstrong number or not. To solve this program we should have a proper concept on Armstrong number, while loop and if-else statement.


What is an Armstrong Numer?

        An Armstrong number is a positive number that is equal to the sum of the power of the digits.

For Example: Let's take 153: 13 + 53 + 33 

                                                    = 1 + 125+ 27 

                                                    = 153

    which means 153 is an Armstrong number.


PROGRAM

#include<stdio.h>
#include<conio.h>
int main()
{
    int num,a,r,sum=0;
    printf("\n Enter the Number : ");
    scanf("%d",&num);
    a=num;
    while(a>0)
    {
        r=a%10;
        sum=sum+r*r*r;
        a=a/10;
    }
    if(num==sum)
    {
        printf("\n%d is an Armstrong Number.",num);
    }
    else
    {
        printf("\n%d is Not an Armstrong Number.",num);
    }
    return 0;
}


OUTPUT

C Program to Check a given Number is Armstrong or Not

C program to convert a decimal number into binary number using function.

 C program to convert a decimal number into binary number using function.     In this example, we  convert the decimal number entered by the user into binary form. Here, in the out put we have taken a decimal number 20 whose binary  is printed as 10100. You can take other numbers such as 15, 13 78, etc... PROGRAM TO CONVERT A DECIMAL NUMBER INTO BINARY NUMBER USING FUNCTION. #include   <stdio.h> #include <conio.h> int  binary( int   b ); void  main() {      int  b;     printf( "\nEnter the Number You want to convert : " );     scanf( "%d" , &b);     binary(b);     getch(); } int  binary( int   b ) {      int  a[10], i, j;      for  (i = 0;  b  > 0; i++)     ...

C Program to Generate Multiplication Table according to User Choice.

 C Program to Generate Multiplication Table according to User Choice.     In this program, we will learn how to print a multiplication table according to any positive number entered by the user. This program uses for loop to solve this problem.  C PROGRAM TO GENERATE MULTIPLICATION TABLE: # include < stdio.h > # include < conio.h > int   main () {      int   i , num , res = 0 ;      printf ( "\n Enter the multplication table you want :  " );      scanf ( " %d " ,& num );      printf ( "\n\n\n\t MULTIPLICATION TABLE OF  %d \t" , num );      printf ( "\n -------------------------------------------------- \n" );      for ( i = 1 ; i <= 10 ; i ++)      {          res = num * i ;       ...

C Program to Check a Whether a Number is Divisible by 5 or Not

 C Program to Check a Whether a Number is Divisible by 5 or Not            In this program we will check a number entered by the user will be divisible by 5 or Not. We have solved this problem using if-else statement. Program: #include <stdio.h> #include <conio.h> int  main() {      int  x;     printf( "Enter a number" );     scanf( "%d" ,&x);      if (x% 5 == 0 )         printf( "The number %d is divisible by 5" ,x);      else         printf( "The number %d is not divisible by 5" ,x);      return   0 ; } Output: NOTE:   You Can Comment Your Code if you have solved differently and we will pin it in the comment section.  Let's Learn toget...

C Program to input Values in a 2x2 square matrix and display the value

 C Program to input Values in a 2x2 square matrix and display the value     In this example, we will accept values from the user in a 2x2 square and matrix and then it is displayed. To solve this problem we must know what is matrices and arrays. What are Arrays?      An array is a data structure for storing more than one data member of similar data type.          Array can be of following types: One-dimensional Array Two-dimensional Array Multi-dimensional Array             In Array we must always initialize values. PROGRAM #include <stdio.h> #include <conio.h> int   main () {      int   a [ 2 ][ 2 ], i , j ;      printf ( "Enter the values of the matrix:" );      for ( i = 0 ; i < 2 ; i ++)     {          for ( j = 0 ; j < 2 ...

C Program to Check Even or Odd Without Modulous and Bitwise Operator

  C Program to Check Even or Odd Without Modulous and Bitwise Operator                   In this example we will check even or odd without Modulous Operator. To do this program we should know what is even and odd number.                   Even Number: Even numbers are those numbers which are divisible by 2. That means if we divide a number by 2 and if its remainder appears 0 then it is an even number.                                 For Example: 2,4,6,8,10,12,.... are all even numbers.                              ...
