Program to Calculate the Discriminant of a Quadratic Equation

To write a program in Pascal to calculate the discriminant of a quadratic equation `ax^2 + bx + c = 0`, you can follow these steps:

1. Declare the variables `a`, `b`, and `c` to store the coefficients of the quadratic equation. 2. Read the values of `a`, `b`, and `c` from the user. 3. Calculate the discriminant `D` using the formula `D = b^2 - 4ac`. 4. Display the value of the discriminant `D`.

Here's an example of how the program could be written in Pascal:

program CalculateDiscriminant;
var
  a, b, c, D: real;
begin
  // Read the coefficients from the user
  writeln('Enter the coefficients of the quadratic equation:');
  write('a: ');
  readln(a);
  write('b: ');
  readln(b);
  write('c: ');
  readln(c);

// Calculate the discriminant
  D := b * b - 4 * a * c;

// Display the value of the discriminant
  writeln('The discriminant (D) is: ', D);

// Wait for the user to close the program
  writeln('Press Enter to exit...');
  readln;
end.

This program prompts the user to enter the coefficients `a`, `b`, and `c` of the quadratic equation and calculates the discriminant `D` using the formula `D = b^2 - 4ac`. Finally, it displays the value of the discriminant.

Please note that this is just one way to write the program in Pascal. There may be other variations or improvements depending on your specific requirements.

I hope this helps! Let me know if you have any further questions.
