C Language - Combination of Loop & Conditional Statements - Write a program to check a given number is Armstrong or not. A number is said to be Armstrong if sum of the cube of the individual digit is equal to the number

Write a program to check a given number is Armstrong or not. A number is said to be Armstrong if sum of the cube of the individual digit is equal to the number.

Example: - 153 = (1)3 + (5)3 + (3)3.

#include <stdio.h>
#include <conio.h>

void main()

{

            int num,num1,digit,arm=0;

            clrscr();

            printf("\nENTER A NUMBER: ");

            scanf("%d",&num);

            num1=num;

            do

            {

                        digit=num%10;

                        num=num/10;

                        arm=arm+(digit*digit*digit);

            }

            while(num!=0);

            if(arm==num1)

                        printf("\n%d IS AN AMSTORNG NUMBER",num1);

            else

                        printf("\n%d IS NOT AN AMSTRONG NUMBER",num1);

            getch();

}
