Armstrong number C program

Advertisement

Armstrong number c program: c programming code to check whether a number is armstrong or not. A number is armstrong if the sum of cubes of individual digits of a number is equal to the number itself. For example 371 is an armstrong number as 33 + 73 + 13 = 371. Some other armstrong numbers are: 0, 1, 153, 370, 407.

C programming code

#include 
 
int main()
{
int number, sum = 0, temp, remainder;
 
printf("Enter an integer\n");
scanf("%d",&number);
 
temp = number;
 
while( temp != 0 )
{
remainder = temp%10;
sum = sum + remainder*remainder*remainder;
temp = temp/10;
}
 
if ( number == sum )
printf("Entered number is an armstrong number.\n");
else
printf("Entered number is not an armstrong number.\n");
 
return 0;
}
