Free Pascal Program Tutorial 12 – Menus For User Friendly Programs – Lazarus

http://www.schoolfreeware.com

Menus are extremely important for directing the user to control the program’s function and understand what the program is capable of doing.

Case statements are an excellent way of making menus. Also, it is a good idea to use input validation to check to see if the user entered correct information into the menu.

    "Else IF" is better if you're doing a nested loop (a repeat inside a repeat) or if you want multiple outcomes if the above statement is not true. Eg:

    If age=15 then (do whatever)
    Else If age=16 then (do whatever)
    Else If age>16 then
    writeln('You are too old');

    or whatever.

    Else IF can make it a cleaner program, easier to follow, and make it look more professional – since it does not need to stack up the lines and will tend to have good indentation.

    There's nothing new, you already uploaded if statements and case of videos. In spite of it, this is very useful video but i'm wondering why don't you write: begin-end; You were always writing this. I've tried this, program works but what's the difference? Should i use begin-end; or not?? (Please, answer me SchoolFreeware, i'm really wondering)…
