What is the purpose of modularity in visual basic?

Answer 1

Just like when you are reading either a book/or, a newspaper. You will notice, whenever you think about it, that the text is not shown just all bunched up together into a tight space; but, instead, is very carefully arranged into such parts as: Headlines/Sub-headers/Indented paragraphs/Quotes/Photos/White space/Margins/seperate Pages/-etc.

In the same way, rather than have everything being most confusingly joined together; programmers like to break up their code into being much smaller parts; which are easier to write/read/understand/debug; and, these seperate blocks of code are what's called: sub-routines/functions/data/-etc.; which are stored inside of seperate code modules.

When the program is run/executed; then, all of these modules load; and, become automatically joined together; with everything working as being just 'one' single program.
