Dynamic 2D array in typedef

Question

How do I get this to work? I am not sure how many invoices a customer will be assigned to and want to leave it dynamic. Please help.

#include 
#in         


        

Answer 1

You can change invoices to int** invoices and then allocate dynamically using malloc(). You can allocate a 2D array like this:

int** theArray;
theArray = (int**) malloc(arraySizeX*sizeof(int*));
for (int i = 0; i < arraySizeX; i++)
   theArray[i] = (int*) malloc(arraySizeY*sizeof(int));
