C program to check number is Krishnamurti number or not

Write a program to print all the Krishnamurti number from 1 to n. Here, n is user dependent. A Krishnamurti number is a number whose sum of factorial of individual digits equals the number.

For example, 145 = 1! + 4! + 5! = 1 + 24+ 120 = 145.

#include<stdio.h>
int factorial(int);
int main()
{
	int num,digit,sum=0,temp;
	printf("Enter any Number : ");
	scanf("%d",&num);
	temp=num;
	while(num>0)
	{
		digit=num%10;
		sum=sum+factorial(digit);
		num=num/10;
	}
	if(sum==temp)
	{
		printf("Number is a Krishnamurti Number");
	}
	else
	{
		printf("Number is Not a Krishnamurti Number");
	}
	return 0;
}
int factorial(int num)
{
	int fact=1;
	while(num>=1)
	{
		fact=fact*num;
		num--;
	}
	return (fact);
}

Enter any Number : 145

Number is a Krishnamurti Number
