How To Identify Armstrong Numbers Using Turbo C Compiler

According to illuminations.nctm.org, an Armstrong number is an n-digit number that is equal to the sum of the nth powers of its digits.

To have a clearer understanding of what an Armstrong number is, I have prepared below a solution on how to determine if a number is an Armstrong or not.

#include<math.h>

#include<stdio.h>

void armstrong(void);

main()

{
clrscr();

armstrong();
getch();

}

void armstrong(void)

{

long count=0,m,n,m1,q,r,a,b,sum=0;

scanf("%ld",&n);

m=n;

m1=n;

for(;n!=0;)

{

r=n/10;

count++;

n=r;

}

for(;m!=0;)

{

a=m/10;

b=m%10;

sum=sum+ pow(b,count);

m=a;

}

if(sum==m1)

{

printf("Armstrong");

}

else

{

printf("Not");

}

}
