Hi. I'm not good with C++. But I have to code this in little function is C++. I'm trying to print out all the values of BSM_European_call from sigma 0.1 to 1.0 using given values of S,K, r, q, sigma, T, t0. It's not printing the correct values. I think I need to use pointers or pass by reference but I'm really not sure how to do it in C++. Please help.
