Check Armstrong Number of n digits

Check Armstrong Number of n digits

In case of an Armstrong number of 3 digits, the sum of cubes of each digits is equal to the number itself.

For example: 407 = 4*4*4 + 0*0*0 + 7*7*7  // 407 is an Armstrong number.

#include <stdio.h>
#include <math.h>

int main()
{
    int number, originalNumber, remainder, result = 0, n = 0 ;

    printf("Enter an integer: ");
    scanf("%d", &number);

     originalNumber = number;
    
    while (originalNumber != 0)
    {
        originalNumber /= 10;
        ++n;
    }

    originalNumber = number;

    while (originalNumber != 0)
    {
        remainder = originalNumber%10;
        result += pow(remainder, n);
        originalNumber /= 10;
    }

    if(result == number)
        printf("%d is an Armstrong number.", number);
    else
        printf("%d is not an Armstrong number.", number);

    return 0;
}

Implementations for Pairing Heap in C++ - "Change the Value" of the item stored in the pairing heap. Does nothing if newVal is larger than currently stored value. p points to node returned by insert. "newVal" is the new value

C++ Compute Power with pow() Function - In this 'C++' sample, you will learn to compute power to a number manually, by using 'pow()' function. Takes two numbers from the user (a base number and an "exponent") & calculates

C Language Continue Statement For Loop - The continue statement is used inside loops. When a continue statement is encountered inside a loop, control jumps to the beginning of the loop for next iteration, skipping the...

Frequency of Characters in a C-style String - In this example, 'frequency of characters' in a String object is computed. To do this, "size()" function is used to find the Length of a string object. Then, the for loop is iterated until the

C++ Find Minimum Element Linear Search - First 'Compare the Element' at the beginning with another array element sequentially. And swap values if the element at the beginning is Larger than the other element. This value will

Code to find the Frequency of Odd & Even - Program code finds frequency of odd & even numbers in the given matrix. The program first accepts the matrix. Then finds the odd and even numbers in a matrix. Then finds the
