Strong number in C

PROBLEM STATEMENT:

A number can be said as a strong number when the sum of the factorial of the individual digits is equal to the number.

For example, 145 is a strong number.

PROGRAM:

#include<stdio.h>

int main() 

{

    int i,a,n,c,fact,sum=0;

    scanf("%d",&n);

    int t=n;

    while(n>0)

    {

        a=n%10;

        fact=1;

        for(i=1;i<=a;i++)

        {

            fact=fact*i;

        }

        sum=sum+fact;

        n=n/10;

    }

    if(t==sum)

        printf("Strong number");

    else

        printf("Not a strong number");

        

    return 0;

}

       

OUTPUT:

145
