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 find out the roots of a Quadratic Equation and also test for Real and Complex roots

 C Program to find out the roots of a Quadratic Equation  and also test for Real and Complex roots.       In this example, we will calculate the roots of the quadratic equation by testing for real and complex roots. We can test real and complex roots by checking these conditions : If b 2  −4 ac  < 0, then there are no real roots. If b 2  −4 ac  = 0, then both the roots are equal. If b 2  −4 ac  > 0, then roots are real and distinct.   PROGRAM TO FIND OUT THE ROOTS OF A QUADRATIC EQUATION. #include <stdio.h> #include <conio.h> #include <math.h> int   main () {      int   a , b , c , d ;      float   x , y ;      printf ( "Enter coefficient of x^2,x and constant : " );      scanf ( " %d   %d   %d " ,& a ,& b ,& c );      d = b * b ...

C Program to Multiply two Matrices

 C Program to Multiply two Matrices.     In this example, we will calculate the product of the two matrices allowing the user to enter their required number of rows and columns. In matrix multiplication the number of columns, in the first matrix must be equal to the number of  rows in the second matrix, otherwise multiplication is not possible. The product will have the number of rows of the first matrix and the number of columns of the second matrix.     Here in the output we have taken two matrices of order 2x3 and 3x2. The resulting matrix after calculating the product will be of the order 2x2. PROGRAM #include <stdio.h> #include <conio.h> void   main () {      int   row1 , row2 , column1 , column2 , i , j , k ;      int   a [ 10 ][ 10 ], b [ 10 ][ 10 ], mul [ 10 ][ 10 ];      printf ( "Enter the row size of the 1st Matrix :...

C Program to Check whether a given number is Perfect or Not

 C Program to Check whether a given number is Perfect or Not. In this exmaple we will learn to check a given number is a Perfect Number or not.  LOGIC OF PERFECT SQUARE NUMBER: At first we have declared variables i , num , sum=0 (value is initialized to zero).  Then we have inputted the number from the user and stored in num. After that we have to to add a loop i=1 till num/2 and to increment the iteration by 1. You all must be thinking why we have to run the loop till n um/2 because a number does not have any positive integer greater than the half of the number that is num/2 . Then we have to check whether the remainder of num%i is equal to zero or not. If it is equal then the value of i is a proper divisor of the number entered by the user and it is added to sum. Now we have to check if the sum of the proper divisors of the number equal to the original number. If it is equal then the number entered by the user is a perfect number otherwise it is not a perfect num...

C Program to Add Two Matrices Using Multi-dimensional Array.

C Program to Add Two Matrices Using Multi-dimensional Array.       In this example, we will add two matrices using multi-dimensional array. Two matrices can be added if they are equal means their order/dimensions must be same. Addition of matrices is performed by adding the corresponding elements of the two matrices.     Here in the Output we have  allowed the user to enter the row and column size of their matrices according to their requirements but they can enter the value of row size and column size less than 100. PROGRAM #include <stdio.h> #include <conio.h> int   main () {      int   row , column , i , j , a [ 100 ][ 100 ], b [ 100 ][ 100 ], c [ 100 ][ 100 ];      printf ( "Enter the row size of the matrices(max. value 100) : " );      scanf ( " %d " ,& row );      printf ( "Enter the co...

C program to read m x n matrix and calculate the Row sum and Column sum of the matrix.

 C program to read m x n matrix and calculate the Row sum and Column sum of the matrix.     In this example, we read a m x n matrix whose value would be entered by the user then the sum of row and column is calculated. Here in the example we have taken a matrix of order 3 x 2 whose row sum and column sum is displayed in the output screen. PROGRAM TO READ m x n MATRIX AND CALCULATE THE ROW SUM AND COLUMN SUM OF THE MATRIX: #include <stdio.h> #include <conio.h> void  main() {      int  i,j,m[100][100],row,column,rsum,csum=0;     printf( "Enter the row size of the matrix :" );     scanf( "%d" ,&row);     printf( "Enter the column size of the matrix :" );     scanf( "%d" ,&column);     printf( "Enter the Matrix : " );    ...
