Check Voting Eligibility
Problem Statement
Write a program that accepts a number (age) and checks whether the person is eligible to vote. A person is eligible if their age is 18 or more.
Example
Input: 20
Process: Check if 20 ≥ 18 → Eligible
Output: You are eligible to vote.
Approach
- Take the age as input (or define it in a variable).
- Use a conditional statement to check whether the age is 18 or above.
- If yes, print "You are eligible to vote."
- Otherwise, print "You are not eligible to vote."
Visualisation
1Store the age
let age = 20;2Check the condition
age >= 18 ?3Yes → eligible
"You are eligible to vote."4No → not eligible
"You are not eligible to vote."Explanation
- Accept the age as input.
- Use
if (age >= 18)to check eligibility. - Exactly one branch runs: the
ifblock when the condition is true, theelseblock otherwise. - Show the appropriate message based on the condition - the logic is the same in every language.
