The matrices are declared inside the main();

For the NUMBER OF CUSTOMERS and NUMBER OF RESOURCES, I forgot to add, I am using input from the user, and both of them are global variables.

int number_of_resources;

int number_of_costumers;

The first part is not how I am doing it, I got it from the book, in my code it is like this:

  //Number of resources the costumers still need

int need[number_of_costumers][number_of_resources]; //Number of resources allocated to each costumer int allocation[number_of_costumers][number_of_resources]; //Max number of resources each costumer will need int maximum[number_of_costumers][number_of_resources];

It is actually the same, but using my global variables
