Factorials) The factorial function is used frequently in probability problems. The factorial of a positive integer n (written n! and pronounced "n factorial") is equal to the product of the positive integers from 1 to n. Write a pseudocode and C++ program that evaluates the factorials of the integers from 1 to 20. Print the results in a tabular format. Here is a sample run for 1 to 5: Factorial of X 1 1 2 4 5 6 24 120
