create an array of marks [1..5] then create a while loops to ask the user for 5 marks then displayed all stired marks.
program marks;
var
mark:array[1..5] of integer;
x:integer;
counter:integer;
Begin
counter:=1;
x:=1;
while (counter<=5) do
begin
writeln('input marks');
readln(mark[x]);
x:=x+1;
counter:=counter+1;
end;
writeln(mark[3]);
end.thankx in advanced for an help
Jump to PostNot sure why you have two integer variables x and Counter. Surely, you could work with Counter alone, couldn't you?

ok i'll work with one integer, but its became a bit complicated. you'll have to make the sum of all the values stored in the array.

program array_sum;
Uses wincrt;
var
nums:array[1..10] of integer;
index:integer;
Sum:integer;
Begin
index:=1;
writeln('Input marks');
while (index<=10) do
Begin
Readln(nums[index]);
index:=index+1;
end;
index:=1;
while (index<=10) do
Begin
sum:=(nums[index]);
index:=index+1
end;
writeln('sum',sum);
end.hope will get a quick reply
dont no what to put there
sum:=(nums[index]);program array_sum;
Uses wincrt;
var
nums:array[1..10] of integer;
index:integer;
Sum:integer;
Begin
sum:=0;//Delphi initializes local variables. Not sure if your Pascal compiler does
index:=1;
writeln('Input marks');
while (index<=10) do
Begin
Readln(nums[index]);
sum:=sum + nums[index];
//you can update sum in the input loop - no need for a separate loop
index:=index+1;
end;
writeln('sum',sum);
end.As a general observation for loops are more efficient - if you know you are working with 10 inputs. If this number is liable to be variable you might need to put in a test for an invalid input and break out of the loop prematurely. In any case, I would suggest some means of allowing for a premature break.
Better use a variable name other than Index - if it clashes with an object property that is in scope, for instance, you can end up with a hard to trace bug.
all work perfectly.
Thankx for ur help.

Yes, but I don't often find time to survey more than one forum here. Try posting to the VB.NET forum - someone is bound to help out.
