cplusplus: oid Convert a double* to double

jeudi 21 juillet 2016

In my code I have to use a function that accepts a double* as an argument

void function_1(int a, double* var){
  (*var) = 0.;
  for (int i=0; i<a.Size(); i++) {
    (*var)+=pow(a[i],2);
  }
  (*var) = (*var)/a.Size();
}

Then I have to use (*var) in another function that needs var as a double

double function_2(double x)

I tried to use

function_2( *(double*) var )

but without any success... Since I am new to c++ I think I am doing something fundamentally wrong. Any help on that?
