1) asks user to enter in 10 numbers (i can do this with array)

2) find the largest number entered and display it

3) find smallest number and display it

4) find average and display it

i am a total noob at pascal and programming. i was close to figuring out average but i couldnt manage. and i have no idea how to display the largest and smallest. could you guys help me?

Hi, this will help to solve your problem:

[code][color=Blue]

program average;

const max_number=10; {change this for array size}

var number:array[1..max_number+1] of integer; {can be byte,word,real...etc.}

i:byte;

procedure sort_numbers; {simple bubble sort algorythm}

var j:byte; {can be slow for large arrays, but easy to implement}

begin

for j:=max_number downto 2 do

for i:=1 to j do

if number[j] ',number[1]); {#13#10 moves the cursor down a line}

writeln('Maximum > ',number[max_number]);

end;

procedure calculate_average;

begin

number[max_number+1]:=0;

for i:=1 to max_number do

inc(number[max_number+1],number[i]);

writeln('Average > ',number[max_number+1]/max_number:6:4);

{ :6:4 formats the result to "xxxxxx.xxxx" instead of "x.xxxx...E+xxxx" }

end;

begin

writeln; {move cursor down 1 line}

for i:=1 to max_number do begin {enter data}

write('Enter number ',i,' : ');

readln(number[i]);

end;

sort_numbers;

write_min_max;

calculate_average;

asm xor ax,ax;int 16h;end; {waits for a keypress to exit}

end.

wow! thanks! works great! exept for the end where it says "asm xor ax,ax;int 16h;end;" it said that the compile failed so i just changed to readln no biggy. i also learnt about the 6:4 thing. that helped alot! thanks

438MemberIt can all be done in a single pass instead of the N-1 passes of a bubble sort.

[code]

Program MinMax ; [red]{ less than 30 non-comment coded lines }

{

: 1) asks user to enter in 10 numbers (i can do this with array)

: 2) find the largest number entered and display it

: 3) find smallest number and display it

: 4) find average and display it

}[/red]

CONST

N = 10 ;

Var

i : Byte ;

x : Array [1 .. N] of Real ;

Min,

Max,

Sum,

Avg : Real ;

begin

[red]{

input phase

}[/red]

for i := 1 to N do begin

Write ('Enter number ', i:0) ;

ReadLn (x[i])

end ;

[red]{

compute phase

}[/red]

Min := x[1] ;

Max := x[1] ;

[red]{

Min and Max must be initialized to something reasonable,

any value in the array will do. Note that 0.0 will not do.

}[/red]

Sum := 0.0 ;

for i := 1 to N do begin

Sum := Sum + x[i] ;

if x[i] < Min then { will not happen when i = 1. That's OK }

Min := x[i] ;

if x[i] > Max then

Max := x[i]

end ;

Avg := Sum / N ; [red]{ N should get "promoted" to a Real }

{

output phase -- output will be in scientific notation

}[/red]

WriteLn ('Largest number entered is ', Max) ;

WtiteLn ('Smallest number entered is ', Min) ;

WriteLn ('Average is ', Avg

end.
