Step Form Algorithm:

  • Start.
  • Declare the required variables.
  • Indicate the user to enter the coefficients of the quadratic equation by displaying suitable sentences using printf() function.
  • Wait using the scanf() function for the user to enter the input.
  • Calculate the roots of quadratic equation using the proper formulae.
  • Display the result.
  • Wait for user to press a key using getch() function.
  • Stop.

Pseudo Code Algorithm:

  • Start.

  • Input a, b, c.

  • D ← sqrt (b × b – 4 × a × c).

  • X1 ← (-b + d) / (2 × a).

  • X2 ← (-b - d) / (2 × a).

  • Print x1, x2.

  • Stop.

Flowchart:

Flowchart to calculate the roots of quadratic equation is shown below in figure 3.
