Question

write a short program to find the oldest person between you and one other individual. Use a flow control statement to print the outcome of the result.

Answer 1

What language do you need to use?

The simplest way to do this is with an if-else statement

if( /*<condition>*/ ) {
//print ....
} else {
//print ....
}

Answer 2

I believe that it is supposed to be switch.

Answer 3

http://en.wikipedia.org/wiki/Control_flow -- All of the general flow control statements for most programming languages.

A switch is not viable since you have two values
Age1 and Age2, there's you wouldn't be able to compare both of those inside a switch, unless your programming language lets you do an evaluation inside a switch, though I don't think it's possible.

Switches are for specific values on a single variable, let's say you expect age to be between 1-100

switch(Age1){
case 1:
case 2:
case 3: System.out.println("Toddler"); break;
case 4:
....
case 12: System.out.println("Kid"); break;
case 13:
...
case 18: System.out.println("Adolescent"); break;
...etc
}

Flow control for comparisons between two variables will usually be if-else
