Strong number:-

The sum of the factorials of digits of a number is equal to the original number.

Ex: n=145=> 1! + 4! + 5! = 1 + 24 + 120 = 145

so it is strong number.

Armstrong number:-

The sum of the cubes of digits of a number is equal to the original number.

Ex: n=153 => 13 + 53 +33 = 1+125+27= 153

so 153 is arm strong number.

C program for strong numbers



void main()


int sof=0,n,dn,ctr,prod,rem;

printf("Enter the number\n");

















printf("The number entered is strong number");




printf("The number entered is not a strong number");



C program for amstrong numbers



void main()


int dn,rem,sum,n;

printf("Enter the number:");




printf("Amstrong number");


printf("Not a amstrong number");
