Chapter 7, Problem 8E

Program Plan Intro

Program Plan:

• Include required header files
• Give the function prototype
• Define the main function
  • Declare the variables “a”, “b”, “c”.
  • Get three numbers from the user.
  • Calculate the value of “res”.
  • Check whether the value of “res” less than “0”.
    • Print the statement.
  • Otherwise, it enters into the else case if the condition fails.
    • Declare the variables “x1” and “x2”.
    • Call the function “squareRoot()” for “x1”.
    • Call the function “squareRoot()” for “x2”.
    • Print the square roots value
    • Return the value “0”.
• Definition for the function “absoluteValue(float x)”
  • Check “x” is less than “0”.
  • Assign “-x” to x“.
  • Return the value of “x”.
• Definition for the function “squareRoot(float x)”
  • Declare the “epsilon” as “float”.
    • Declare the variable “guess” as “float”.
      • Call the function “absoluteValue()”.
        • Compute the value of guess.
      • Return the value of guess.
