recursioncprogramfactorial 8th Mar 2019, 5:25 PM Manikanta KVV 1 AnswerAnswer + 1 int fac (int n) { if (n < 0) return -1; //n must be positive if (n <= 1) return 1; return n * fac (n-1); } n <= 1 will be the condition to exit our recursion. Let's say n is 3...
What's a Factorial in Mathematics? In mathematics, the factorial of apositive integer n, denoted byn!, is the product of all positive integers less than or equal to n: Note: Factorial is only defined fornon-negativenumbers. (>=0) The value of 0 factorial is 1. (0! = 1) //as we...

Write a program in C++ that evaluates the factorials of the integers from 1 to 20. Write a program that takes in an input and calculates its factorial. (For example, the factorial of 1 is 1, the factorial of 2 is 1 * 2 = 2, the factorial of 3 is 1...
When call of factorial(1) get executed then it returns value 1 so statement f=2*factorial(1) becomes f=2*1 i.e. 2. This value get return to statement f=3*facttorial(2) so it becomes f=3*2 i.e. 6 and so on. In recursive functions recursive statements are hold on stack ...
