Hello Coding Students welcome to my programming shortcut
Today write a program to check a number is an Armstrong number or not in c .
What are Armstrong numbers ?
Armstrong number is a number that is equal to the sum of the cube of each digit number
Example of Armstrong number
153=
1^3=1
5^3=125
3^3=9
1+125+9=153
So 153 is an Armstrong number
#include<stdio.h>
int main(void)
{
int num,temp,cube,d,sum;
printf(“Enter a number :\n”);
scanf(“%d”%num);
temp=num;
sum=0;
while(n>0) /*inner loop to calculate sum of cube of digits*/
{
d=n%10;
n/=10;
cube=d*d*d;
sum=sum+cube;
}/*End of while loop*/
num=temp;
if(num==sum){
printf(” %d is a armstrong number”,num)
}else{
printf(“%d is not armstrong number, Please try other number”,num);
}
return 0;
}
output
1st run
Enter a number: 123
123 is not Armstrong number, Please try another number
2nd run
Enter a number: 153
153 is an Armstrong number
