Explanation:

You can use conditional expressions (such as if-else or a ternary operator) in a simple way to determine which of three values is the largest.

Logic to Find the Largest of Three Numbers

  1. Input three numbers: a, b, and c.
  2. Compare the numbers:
    • First, check if a is greater than or equal to both b and c.
    • If not, check if b is greater than or equal to both a and c.
    • Otherwise, c will be the largest number.
  3. Output the largest number.
