Draw out control flow graph based on the image given 

The following function in Figure 2 shows a function to calculate a factorial for any input number. int factorial (int n) { /* Calculate a factorial using loop. * A factorial of a number is the product * of the number itself times the factorial * of the number minus 1; i.e n! = nx (n-1) x ..1 int f = -1; if (n < 0) { cout << "Error, Factorial: Negative argument." << \n; } else { f = 1; for (int i=2; i<=n; i++) f = f*i; } return (f);
