In this tutorial we are writing a Shell Program to Check Eligibility for voting.
To check that a person is eligible for voting or not, we need to check whether person’s age is greater than or equal to 18. For this we are reading age in a variable a and checking the condition a>=18, if the condition is true, “person will be eligible for voting” else not.
