how to make an array of structures ? and after how to modify it

[Timur]

Good day.

how to make an array of structures ? Let's say there is a food warehouse, I need to store nuts-500 (pieces), vegetable oil-20... the names of the products are unknown in advance (I can't know either the names of the products or their quantity at the compilation stage), but during the program (the program reads certain information from the file), it is necessary to store the name of the product and its quantity in the heap (analogous to the C language structures). That is, I need an array of such structures (product, quantity). It is also necessary to somehow be able to change the amount of a certain product after filling this array, let's say it suddenly became necessary to change the amount of oil, then how to do it?

include lib/ncoding.4th

( define the structure )

struct

  64 +field name

  nell +field quantity

end-struct /product

( define number of products)

500 constant #product

( define an array of structs)

#product /product * buffer: products does> swap /product * + ;

( now enter the values)

s" nuts"  0 product -> name place

500 0 product -> quantity n!

s" vegetable oil" 1 product -> name place

20 1 product -> quantity n!
