What is a prime number?

The prime numbers are those numbers that are only divisible by themselves. These numbers can’t be complete, divide by the 2 & 3.

What is an Armstrong number?

Armstrong number is a number that is equal to the sum of cubes of its digits.

For example 
0, 1, 153, 370, 371 and 407 are the Armstrong numbers.

1 2	For example 0, 1, 153, 370, 371 and 407 are the Armstrong numbers.

What is a Perfect number?

A perfect number is a positive integer that is equal to the sum of its positive divisors, excluding the number itself.

For Example:-

6 has divisors 1, 2 and 3 (excluding itself).

And 1 + 2 + 3 = 6. 

So 6 is a perfect number.

For Example:-

6 has divisors 1, 2 and 3 (excluding itself).

What is a Strong number?

A strong number is a number whose sum of all digits’ “S” factorial is equal to the number “N”. Let S be the sum of FACTORIAL of all the digits in a number is equal to its original number.

<strong>For Example: 

145 is a strong number. 

Since, 1! + 4! + 5! = 145. </strong>

For Example:

145 is a strong number.

Since, 1! + 4! + 5! = 145.

Algorithm:-

1. Declare the variables for the program. 

2. Taking the input number from the user to check. 

3. Checking if the number is the <strong>strong Number or Not</strong>.  

4. Print the Result. 

5. End the program.

    scanf("%d", &no);

    /* Copy the value of no to a temporary variable */
    orgno = no;

    sum = 0;

    /* Find sum of factorial of the digits */
    while(no > 0)
    {

        /* Get last digit of no */
        lastDigit = no % 10;
        /* Finding the factorial of last digit */
        fact = 1;
        for(i=1; i<=lastDigit; i++)
        {

        }
        /* Add factorial to sum */
        sum = sum + fact;
        no = no / 10;
    }
    /* Check Strong number condition */
    if(sum == orgno)
    {
        //Printing the output after checking the number
        printf("%d is STRONG NUMBER", orgno);
