Declare the needed variables. There will be one use input) // 2. Immediately call the functions passing the number n // 3. For the Ifactorial use a loop to calculate n! // 4. For the Rfactorial you CANNOT use a loop. // The recursive behavior will handle the computation. // 5. Print both values and check they are equal. // 1/ Note: Recall: 5! = 5 * 4 * 3 * 2 1 - 120 // 0! = 1 // // *** * #include using namespace std; // Header file needed for I/O // Line used for simplicity long Ifactorial(int n); long Rfactorial(int n); // --- int main() // 1. Declare the variables needed for this program int n; long Ifact, Rract; // Because n! generates very large numbers // 2. Call both functions // Write their definitions BELOW the main program // Functions ALWAYS are written below main at this level Ifact Ifactorial(n) Rfact - Rfactorial(n); 77 Non recursive function, line 58 // Recursive function line 65 1/ 3.
