Hello, everyone,

I am using CPLEX to solve an optimization problem.  In the program, I have to creat a three-dimensional array in C/C++, but I  don't know how to do this.

Can anyone help me this? 

Thank you in advance.

Please search this Forum for an answer. This question has been asked and answered multiple times before.

Building three-dimensional arrays for plain data types should be straightforward in C++.

For building three-dimensional arrays of Ilo objects you could make use of the IloArray<> template:

typedef IloArray<IloArray<IloArray<IloNumVar> > > IloNumVar3D;

There are more sophisticated ways to do that, you will find them if you search this Forum.
