Factorial Program in C++: Factorial of n is the product of all positive descending integers. Factorial of n is denoted by n!. For example:
Here, 4! is pronounced as "4 factorial", it is also called "4 bang" or "4 shriek".
The factorial is normally used in Combinations and Permutations (mathematics).
There are many ways to write the factorial program in C++ language. Let's see the 2 ways to write the factorial program.
- Factorial Program using loop
- Factorial Program using recursion
