Assigning a name to ecah componnet of 3D array

[learner999]

Hello everyone,
I have a 3D array which I want to give name. I do, but it gives me an error about BestX (says that it must be a class ,what is wrong here? Can you tell me please ? Thank you so much

  	char varName[1000];
	vector<vector<vector<double>>> BestX(nbP, vector<vector<double>>(nbM, vector<double>(nbPe)));
	for (IloInt i = 0; i < nbP; i++) {
		for (IloInt j = 0; j < nbM; j++) {
			for (IloInt k = 0; k < nbPe; k++) {
				printf(varName, "BestX_%d_%d_%d", (int)i, (int)j, (int)k);
				BestX[i][j][k].setName(varName);
			}
		}
	}

BestX[i][j][k] is double (which certainly has no member function setName(...)).

What do you expect that has a member function setName(...)?

Also, line 6 should be sprintf(), not printf()

Why do you want to assign names to each item in the array? What would you do with these names?
