1. Start the flowchart with a Start symbol.

2. Input the number (7 in this case).

3. Check if the number is greater than zero using a decision diamond.

4. If yes, print "Pos" and end.

5. If no, check if the number is less than zero.

6. If yes, print "Neg" and end.

7. If no, it means the number is zero, so print "Zero" and end.

This flowchart clearly shows the logic to classify a number as positive, negative, or zero.

Variations - 2 Challenges

[beginner] Draw a flowchart to check if a number is even or odd. Use the number 12 as input.

[intermediate] Draw a flowchart to find the largest of three numbers: A=15, B=23, C=8.
