I need a C++ code for this assignment, please read the question then answer.

7 Homework: Binomia l model 7.1 Function signature Let us write asunple (but working) C++ function to implement the binomial model. The input arguments are 1. The stock price S 2. The strike price K 3. The risk-free interest rate r. (We shal use decima, not percent.) 4. The continuous dividend yield q. (We shall use decimal, not percent.) 5. The stock volatility . (We shall use decimal, not percent.) 6. The expiration time T. (Measured in years.) 7. The current time to. (Measured in years.) 8. boolean "call" (true for a call, false for a put) 9. boolean "American true for an American option, false for European) 10, int n, the number of timesteps (n >= 1) 11. reference to double, output the option fair value V e The function signature is int binomial simple(double S, double K, double r, double q double sigma, double T double to, bool call, bool American int n, double & V)
