Algorithm to find sum of given data values until a negative value is entered:

Here are the solutions to your assignments: 1. Algorithm to find sum of given data values until a negative value is entered: ` Algorithm: SumUntilNegative 1. Initialize SUM = 0 2. Start Loop: 3. Read NUMBER 4. If NUMBER < 0 Then 5. Exit Loop 6. Else 7. SUM = SUM + NUMBER 8. End If 9. End Loop 10. Print SUM 11. End ` 2. Algorithm and Flowchart to compute the volume of a sphere: Algorithm: ` Algorithm: CalculateSphereVolume 1. Start 2. Define PI = 3.1416 3. Read RADIUS (r) 4. Calculate VOLUME (V) = (4/3) PI r^3 5. Display VOLUME (V) 6. End ` Flowchart (text description): Start (Terminal shape) Set PI = 3.1416 (Process shape) Input RADIUS (r) (Input/Output shape) Calculate VOLUME = (4/3) PI * r^3 (Process shape) Output VOLUME (Input/Output shape) End (Terminal shape) 3. Pseudocode for how to polish your shoes: ` Pseudocode: PolishShoes 1. Start 2. Gather materials: shoes, shoe polish, brush, soft cloth. 3. Clean shoes: Use the soft cloth to wipe off any dirt or dust from the shoes. 4. Apply polish: Take a small amount of shoe polish with the brush and apply it evenly over the entire surface of the shoes. 5. Let dry: Allow the polish to dry for a few minutes. 6. Buff: Using a clean section of the soft cloth, rub the shoes vigorously until they achieve a desired shine. 7. End ` 4. Algorithm to input three sides of a triangle and print if it is scalene, isosceles or equilateral: ` Algorithm: ClassifyTriangle 1. Start 2. Read side A, side B, side C 3. If (A + B > C) AND (A + C > B) AND (B + C > A) Then 4. If (A = B) AND (B = C) Then 5. Print "Equilateral Triangle" 6. Else If (A = B) OR (B = C) OR (A = C) Then 7. Print "Isosceles Triangle" 8. Else 9. Print "Scalene Triangle" 10. End If 11. Else 12. Print "Invalid Triangle (sides cannot form a triangle)" 13. End If 14. End ` 5. Flowchart for buying stationery from the market (text description): Start (Terminal shape) Make a list of needed stationery items (Process shape) Decision: Do I have enough money? (Diamond shape) If No: → Go to ATM / Borrow money (Process shape) → Connects back to "Decision: Do I have enough money?" If Yes: Go to the stationery shop (Process shape) Find the required items (Process shape) Decision: Are all items available? (Diamond shape) If No: → Go to another shop / Buy alternatives (Process shape) → Connects back to "Find the required items" If Yes: Go to the billing counter (Process shape) Pay for the items (Process shape) Collect the items and receipt (Process shape) Return home (Process shape) End (Terminal shape) 6. Flowchart for the steps required to play music stored in a CD (text description): Start (Terminal shape) Get a music CD (Process shape) Get a CD player (Process shape) Decision: Is the CD player plugged in and powered on? (Diamond shape) If No: → Plug in CD player and turn on power (Process shape) → Connects back to "Decision: Is the CD player plugged in and powered on?" If Yes: Open the CD tray (Process shape) Place the CD into the tray (label side up) (Process shape) Close the CD tray (Process shape) Decision: Are speakers/headphones connected and turned on? (Diamond shape) If No: → Connect speakers/headphones and turn on (Process shape) → Connects back to "Decision: Are speakers/headphones connected and turned on?" If Yes: Press the 'Play' button on the CD player (Process shape) Adjust volume (Process shape) End (Terminal shape) 7. Flowchart to accept two numbers, if the first number is greater than the second number, print their sum, otherwise print their product (text description): Start (Terminal shape) Input Num1 (Input/Output shape) Input Num2 (Input/Output shape) Decision: Is Num1 > Num2? (Diamond shape) If Yes: → Calculate SUM = Num1 + Num2 (Process shape) → If No: → Calculate PRODUCT = Num1 Num2 (Process shape) → Output Result (SUM or PRODUCT) (Input/Output shape - where the two paths merge) End (Terminal shape)
