fct.pas

This ar the basic programs that i did in highschool. From very simple to medium programs. From array

program functie_function;
{                             2x+1, pt. x>=-1
Sa se calculeze f:R-R; f(x)=
                              3x+2, pt. x<-1

Sa sa calculeze: f(1)+f(2)+...+f(n)}
var i,n:integer;
    s:real;
    a:array[1..100] of real;
                       function fct(x:real):real;
                                 begin
                                      if x>=-1 then fct:=2*x+1
                                               else fct:=3*x+2;
                                 end;
begin
readln(n);
s:=0;
for i:=1 to n do
         begin
              write('a[',i,']= ');
              readln(a[i]);
         end;
i:=1;
repeat
        begin
        writeln(fct(a[i]):4:1);
        s:=s+fct(a[i]);
        i:=i+1;
        end;
until i=n+1;
writeln('f(1)+...f(',n,')= ',s:4:1);
end.
