Answer 2

To solve this problem, you can write a program in Pascal that prompts the user to enter a number and then counts how many times that number appears in a 10x10 two-dimensional array of real numbers. Here's an example implementation:

program CountOccurrences;

const
  SIZE = 10;

type
  RealArray = array[1..SIZE, 1..SIZE] of real;

var
  arr: RealArray;
  number: real;

procedure InitializeArray(var arr: RealArray);
var
  i, j: integer;
begin
  for i := 1 to SIZE do
    for j := 1 to SIZE do
      arr[i, j] := random(100); // You can modify this to initialize the array with your own values
end;

function CountOccurrencesInArray(arr: RealArray; number: real): integer;
var
  i, j, count: integer;
begin
  count := 0;
  for i := 1 to SIZE do
    for j := 1 to SIZE do
      if arr[i, j] = number then
        count := count + 1;
  CountOccurrencesInArray := count;
end;

begin
  InitializeArray(arr);
  
  writeln('Enter a number:');
  readln(number);
  
  writeln('The number ', number:0:2, ' appears ', CountOccurrencesInArray(arr, number), ' times in the array.');
end.

In this program, the `InitializeArray` procedure is used to initialize the 10x10 array with random real numbers. You can modify this procedure to initialize the array with your own values if needed.

The `CountOccurrencesInArray` function takes the array and the number entered by the user as parameters and counts how many times the number appears in the array. It uses nested loops to iterate over each element of the array and compares it with the input number.

Finally, the program prompts the user to enter a number, calls the `CountOccurrencesInArray` function to count the occurrences of that number in the array, and displays the result.

Please note that this is just one possible implementation of the program. There are many ways to solve this problem, and you can modify the code according to your specific requirements.
