Armstrong Number In C Programming Language

Armstrong Number In C is the number that is equal to the sum of all digits to the power of the total number of digits in that number. To understand better check this example given below:

Eg:- The Number 153 which is an Armstrong number

Let’s Prove that this number is Armstrong number:

Total digits in number = 3

1^3 = 1*1*1 = 1

5^3 = 5*5*5 = 125

3^3 = 3*3*3 = 9

S0, 153 = (1*1*1)+(5*5*5)+(3*3*3)

153= 1+125+27 , Hence Proved

Armstrong Number In C Program Code:

#include<stdio.h>  
 int main()    
{    
int num,r,sum=0,temp;    
printf("enter the number=");    
scanf("%d",&num);    
temp=num;    
while(num>0)    
{    
r=num%10;    
sum=sum+(r*r*r);    
num=num/10;    
}    
if(temp==sum)    
printf("armstrong  number ");    
else    
printf("not armstrong number");    
return 0;  
}
