I have created an array of doubles using the following code: double *points = new double[(ii+1)*(jj+1)*(kk+1)*3];
If I have 3 pointers to double : rdf1 = new double [n]; rdf2 = new double [n]; rdf3 = new double [n]; I want to delete them with a single delete statement. something like :
Note that the question has been changed and no longer matches the answers I\'m trying to create memory to hold a buffer of floats (here, 4 floats).
Brief Description In a previous post I asked around about a problem with dangling pointers. I understood that I\'m advised to use Boost and I will rewrite my program as soon I fully got the basics ab
