An array containing natural elements is given. Count the number of two-digit elements in the array.

program zz1;
const n = 15; // set the number of elements in the array
var i, k: integer; // set variables of integer type
m, v: array [1..n] of integer;
begin
for i: = 1 to n do // get n random numbers and write them into an array
m [i]: = random (21);
for i: = 1 to n do // display the array on the screen
write (m [i], ”);
writeln; // go to a new line to display the response
for i: = 1 to n do
if (m [i]> 9) and (m [i] <100) then k: = k + 1;
writeln (‘number of two-digit elements =’, k); // display the answer
end.
