You're on a roll — Step 1: Analyze the flowchart. The flowchart describes a program that calculates the roots of a quadratic equation using the quadratic formula. It takes three inputs: a, b, and c. It first calculates the discriminant D = b^2 - 4ac. Then, it checks if D < 0. If D < 0, it prints "NO real solution". If D 0, it calculates two roots, X_1 and X_2, and then prints them. Step 2: Convert the flowchart to pseudocode. Each symbol in the flowchart corresponds to a specific pseudocode construct. Start and Stop correspond to Begin and End. Enter a, b, c corresponds to Input a, b, c. D = bb - 4ac corresponds to an assignment statement. The diamond shape Is D < 0 corresponds to an If-Else statement. Print "NO real solution" corresponds to a Display statement. The formulas for X_1 and X_2 correspond to assignment statements. Note that the formulas in the flowchart are written as X_1 = (-b + square root D)/2=a and X_2 = (-b - square root D)/2=a. This seems to be a slight error in the flowchart, as the denominator for the quadratic formula is 2a, not just 2=a. I will interpret it as 2 × a. Print X1, X2 corresponds to a Display statement. Step 3: Write the pseudocode. ` Begin Input a, b, c D = (b b) - (4 a * c) If D < 0 Then Display "NO real solution" Else X1 = (-b + square_root(D)) / (2 * a) X2 = (-b - square_root(D)) / (2 * a) Display X1, X2 End If End ` The pseudocode corresponding to the flow chart is: ` Begin Input a, b, c D = (b b) - (4 a * c) If D < 0 Then Display "NO real solution" Else X1 = (-b + square_root(D)) / (2 * a) X2 = (-b - square_root(D)) / (2 * a) Display X1, X2 End If End ` Got more?
