ARMSTRONG NUMBER
Aim:
To write a C program for finding whether a given number is Armstrong number or not using loop control statements.
Algorithm:
1. Start the program.
2. Take number input from user store it in ‘number’.
3. Store that number into ‘temp’ temp:=number;
4. while temp!=0 do,
remainder:=temp%10;
sum:=sum+remainder*remainder*remainder;
temp:=temp/10;
End while
5. if number==sum then, print number is armstrong else print number is not armstrong
6. Stop the program
Program:
/*Armstrong Number*/
#include int main()
{
int n, n1, rem, num=0;
printf(“Enter a positive integer: “);
scanf(“%d”, &n); n1=n; while(n1!=0)
{
rem=n1%10; num+=rem*rem*rem; n1/=10;
}
if(num==n)
printf(“%d is an Armstrong number.”,n);
else printf(“%d is not an Armstrong number.”,n);
}
Output:
Enter a positive integer: 371 371 is an Armstrong number.
