Logic To Determine Youngest of Three

In this C program we ask the user to enter age for 3 people – Ram, Shyam and Ajay. We store it inside the address of variables ram, shyam and ajay.

We check if Ram’s age is less than or equal to Shyam and Ajay’s age. If true Ram is the youngest person.

We check if Shyam’s age is less than or equal to Ram and Ajay’s age. If true Shyam is the youngest person.

We check if Ajay’s age is less than or equal to Ram and Shyam’s age. If true Ajay is the youngest person.

We write separate if condition for each person. If we take else if clause it gives wrong result when 2 or more people have same age.
