simple program pascal.

In the learning college state university smester 1 in Manado (UNIMA) I got the job of lecturer in programming concepts to create a simple program, there are many permasalahn ayng in convey to our faculty to finish using the program, and finally by learning to my friends I could create a simple program that is the
program calculates the triangle area, masi many programs can I make using the Paskal but at the moment we first learned about making the program calculates the area. presumably a simple program that I made this can be useful to friends who are currently difficult to create a task or learn to program using PASCAL, if there are questions about the program please make a comment on comments index below.


program_calculates_the_area_of_triangle;
uses crt;
var A,T,luas : real;


begin
clrscr;
write('input pad value :'); read (A);
write('input of high value :'); read (T);
writeln;

luas :=1/2*A*T;

writeln('jumlah nilainya adalah ', luas:9:2);

readkey;
