We are going to set up three threads, each of which is assigned a target function. When the target function is executed and terminated, the function name is appropriately printed out.

For this example, the output should look like this (even if the order shown cannot be the same):

function_A--> starting 
function_B--> starting 
function_C--> starting 


function_A--> exiting 
function_B--> exiting 
function_C--> exiting
