Factorial Correct

# Our Objective

To implement a program that finds the factorial of a given number.

# The Theory

In Mathematics, factorial is an important function, which is used to find in how many different ways things can be arranged or ordered from a set of numbers. The well known interpolating function of the factorial function was discovered by Daniel Bernoulli. The factorial concept is used in many mathematical concepts such as probability, permutations and combinations, sequences and series, etc. In short, a factorial is a function that multiplies a number by every number below it until the number 1. For example, the factorial of 3 represents the multiplication of numbers 3, 2, 1, i.e. 3! = 3 × 2 × 1 and is equal to 6.

# Learning Outcomes

• Understanding the concept of the factorial function: Implementing a factorial program helps learners understand the mathematical concept of the factorial function and how it works.
• Practice with loops and recursion: A factorial program is often implemented using loops or recursion, which provides learners with practice in these programming techniques.
• Problem-solving skills: Implementing a factorial program requires learners to break down a problem into smaller steps and develop a plan to solve it. This helps learners develop their problem-solving skills.
• Debugging skills: Implementing a factorial program often involves debugging errors that arise during implementation, which helps learners develop their debugging skills.
• Algorithmic thinking: A factorial program involves developing an algorithm to solve a problem, which helps learners develop their algorithmic thinking skills.
• Understanding of data types: Implementing a factorial program requires knowledge of integer data types and their limitations, helping learners understand the importance of data types in programming.
• Practice with basic syntax: Implementing a factorial program involves using basic programming syntax such as variables, functions, and operators, helping learners practice and solidify their understanding of these concepts.
