A factorial program is a program that calculates the factorial of a given number.

• Factorial of a number is the product of all positive integers up to that number.

• For example, the factorial of 5 (5!) is 5 x 4 x 3 x 2 x 1 = 120.

• Factorial program can be implemented using loops or recursion in programming languages like C, Java, Python, etc.

A prime number is a number greater than 1 that has no positive divisors other than 1 and itself.

• Check if the number is greater than 1.

• Loop through numbers from 2 to the square root of the number and check if any of them divides the number evenly.

• If no divisor is found, the number is prime.

To check if a number is even, divide it by 2 and see if there is a remainder.

• Divide the number by 2

• If there is no remainder, the number is even

• Example: 6 divided by 2 equals 3 with no remainder, so 6 is even
