5.12 Factorial of an inputted integer Write a recursive function called factorial) to return the factorial of an integer that was inputted from keyboard The printing of output will be done in the main function The factorial of nis n' which is given by n(n-1)(n-2) 21 Hence the factorial of 5 is 5X4X3X2X1 = 120. Similarly, the factorial of 4 is 4X3X2X1 = 24 Ex. If the inputs 5 the output is The factorial of 5 120 main.cpp Loa 1 #include 2 using namespace std; 3 4 int factorial(int value) 5 6 if (value > 0) 7 return value"factorial(value-1); B return 1: int num; 10 11 int main() 12 cout > num; 15 10 cout
