- C++ For the following code: int fact(int n) { if (n == 0) return 1; else return n * fact(n - 1); } Which of the following are true? A. Group of answer choices B. This function is not recursive. C. This function is recursive. D. The base case is when n!=0 E. The base case is when n ==0Which of the following statements are correct? (Select all that applies.) Group of answer choices a) Recursion is a technique by which a function makes one or more calls to itself during execution. b) Tail recursion occurs when a function in which the recursive call is the last thing that the function does. c) Our Python interpreter throws an exception when there is no base condition defined.- c program only Hi! Could you help me? I think something is wrong with my code but I couldn't figure out what. Also, please help me fix the `factorial` function, for it should apply recursion. Thanks! #include<stdio.h> int factorial(int n); int main(void) { int n; printf("Enter n: "); scanf("%d", &n); printf("Factorial of %d is %d", n, factorial(n)); return 0;} int factorial(int n) { if(n <= 1) { return 0; }else{ return factorial(n-1)*n; }} You can see below the attached pic of how the output should be
- Convert the following function to one that uses recursion. void sign(int n) { while (n > 0) {cout << "No Parking\n"; n--;} }Demonstrate the function with a driver program.Write a recursive function diff which takes two positive integer arguments (x and y) and returns |x – y|. You may not perform an x - y calculation anywhere in the function! Example calls: diff(3, 7) returns 4; diff(7,3) returns 4 In JAVAConsider the following recursive function: void exercise(int x) { if (x > 0 && x < 10) { cout << x << " "; exercise(x + 1); } } What is the output of the following statements? a. exercise(0); b. exercise(5); c. exercise(10); d. exercise(-5);
