Check The Given Number Is An Armstrong Number Or Not
Source code :-
#include<stdio.h>
#include<math.h>
int main()
{
int n,z,r,s,i;
printf("Enter the number: ");
scanf("%d",&n);
z=n;
i=0;
while(z!=0)
{
i++;
z=z/10;
}
z=n;
s=0;
while(z!=0)
{
r=z%10;
s=s+pow(r,i);
z=z/10;
}
if(s==n)
printf("\nThe enter number %d is an armstrong number.\n",n);
else
printf("\nThe enter number %d is not an armstrong number.\n",n);
return 1;
}
Input-Output :-
abhi@hp-15q-laptop:~$ gcc armstrong.c -lm
abhi@hp-15q-laptop:~$ ./a.out
Enter the number: 145
The enter number 145 is not an armstrong number.
abhi@hp-15q-laptop:~$ gcc armstrong.c -lm
abhi@hp-15q-laptop:~$ ./a.out
Enter the number: 153
The enter number 153 is an armstrong number.
Print All The Armstrong Number Of The Given Range
Source code :
#include<stdio.h>
#include<math.h>
int main()
{
int n,z,r,s,i,a,b;
printf("Enter the lower limit of the range: ");
scanf("%d",&a);
printf("\nEnter the upper limit of the range: ");
scanf("%d",&b);
printf("\nArmstrong numbers are: \n\n");
for(n=a;n<=b;n++)
{
z=n;
i=0;
while(z!=0)
{
i++;
z=z/10;
}
z=n;
s=0;
while(z!=0)
{
r=z%10;
s=s+pow(r,i);
z=z/10;
}
if(s==n)
printf("%d ",n);
}
return 1;
}
Input-Output :
abhi@hp-15q-laptop:~$ gcc armstrong.c -lm
abhi@hp-15q-laptop:~$ ./a.out
Enter the upper limit of the range : 1
Enter the lower limit of the range : 200
Armstrong numbers are : 1 2 3 4 5 6 7 8 9 153
