The body of the fact function in order to calculate the factorial of the entered number by the user can be as:

(Hint: e.g: factorial of 6 = 720)

Select one: a. if (num == 0) return 1; else return num * fact(num + 1); b. if (num == 1) return 1; else return num * fact(num - 1); c. if (num == 0) return 1; else return num * fact(num - 1); d. if (num == 0) return 1; else return num + fact(num - 1);
