Question

How do I write a program in Pascal that finds the index of the minimum number of an array(using Function) and replaces it to a number inputted from the keyboard ?(Input and output of the array is a Procedure).

Answer 1

Answer:

program arraysminfinder;

procedure minreplace();

var

no: array [1..10] of integer;  (*no is an array of integers, 10 in all *)

a: integer= 0;

i: integer= 0;

c: integer= 0;

k: integer=0;

N: integer=0;

begin

(* We need to first initialize the array no with 0 values *)

for a := 1 to 10 do

no[a]:=0;

c:=no[1];

for a := 1 to 10 do

begin

  if (no[i]<c) then

  begin

   c:=no[i];

   k:=i;

  end

  else

  begin

      i:=i+1;

  end

 end;

  writeln('Enter the new number:');

  read(N);

  no[k]:=N;

  for a := 1 to 10 do

  begin

     writeln('The array elements are:',no[a]);

   end;

end;

begin

end.

Explanation:

The program is as above.  I have used a function, a for loop, an array of integers, and the if then else ladder for getting the desired output as mentioned in the program. If in case you want procedure for input and output, create a procedure like:

procedure replacenum():integer;

Begin

 writeln("Enter the new number:" N);

    no[k]:=N;

   for a := 1 to 10 do

         writeln("The array elements are:"no[a]);

 end.

Similarly you can make a procedure for input.
