i am trying to come up with code to make a pascal triangle using dynamic array this is what i have come up with so far. i need some explaination about some part of the code... thanks the code that i have question with is encircled with [???????], also can you tell me if my code is the right or wrong because i need it to be made with matrix(dymanic matrix) that why i declare it at a line.

thanks guys
